Multiple Cable Gland – The Complete FAQ Guide

Have you ever owned a cable that had more than one inner cable? If so, it must have been hard for you to terminate your cable’s ends properly.

It’s true that:

There are situations where you’ll have to terminate the ends of several cables all at once, in the same passage. This means that you’ll have to use special cable glands called multiple cable glands.

This guide focuses primarily on multiple cable glands. You are going to learn:

• What multiple glands, their types, and how they work
• The components of a multiple cable gland and how to install them
• Where you can acquire high-quality multiple cable glands

Keep reading this guide to find out more.

Q1. What Is A Multiple Cable Gland?

A multiple cable gland works just the same as a typical cable gland. The primary difference is that the multiple cable glands can terminate the ends of several mini-cables.

                                                           Figure 1: Multiple Cable Gland

A multiple cable gland can terminate several cables at once. It can have a minimum of two cables to terminate their ends.

There are different types of multiple cable glands, as well as the materials used to make them. You’ll learn about all this as you continue reading this guide.

Q2. What Is Material Used To Make Multiple Cable Glands?

Top manufacturing companies make multiple cable glands using the following materials:

• Brass
• Stainless Steel
• Nylon

All of the above materials have their benefits in general. However, they each have their specific benefits, depending on the material used to make them. The best material to use for your cable gland depends on the tasks, environment, and cable configuration of your cable.

Cable configuration simply means the dimensions and structure of your cable. Today, there are different types of cables in the market. There are armored and unarmored cables.

Here’s the deal:

Multiple cable glands are highly beneficial, regardless of the material used to make them. Different materials work better than others depending on the environmental condition from where they will work.

Q3. What Are The Components Of Multiple Cable Glands?

A multiple cable gland has five components that enable it to perform as it should.

Check them out:

The internal components of a multiple cable gland include a lock nut, an O-Ring, the cable glands body, seal, and the sealing nut.

Locknuts are essential devices that are used for securing your cable into position. The O-Ring is then used on the connection thread of your cable gland. It prevents the entry of contaminants like dust, water, oil, moisture from getting into the cable’s connection.

The seal is a key component of the multiple main glands as it determines the number of cables you can gland simultaneously.

                                                   Figure 2: Multiple Cable Glands Internal Components

Q4. How Many Cables Can A Multiple Cable Gland Hold?

A multiple cable gland can hold a minimum of two cables. The maximum number of cables a multiple cable gland can hold depends on your needs. You can have custom multiple cable glands to meet your requirements.

The more holes your multiple cable gland seal has, the lesser the diameter of the holes through which your cable should pass.

Remember:

The key determinant in how many cables your multiple cable gland can hold is the seal. The seal has different cable holes with different dimensions. The dimensions are dependent on what you need.

You may also have differently-sized cables that need glanding through one cable gland. You can have custom-made cable glands to meet your needs. Contact a reputable cable gland manufacturing company today to help you out with what you require.

Q5. What Are Different Types Of Multiple Cable Glands?

There are two types of multiple cable glands basing them on compression:

• Single compression multiple cable glands
• Double compression multiple cable glands

Check this out:

Now, single compression multiple cable glands are suitable for lightly armored cables. Single compression multiple cable glands are made up of a flat washer, lock nut, washer and a multihole seal.

                                                     Figure 3: Single Compression Multiple Cable Gland

The double compression multiple cable gland, on the other hand, is ideal for heavily armored cables. They are made up of a compression seal fitting, an armor clamping cone and ring, and a sealing washer.

Figure 4: Double Compression Multiple Cable Gland

The compression seal fitting closes the wire. The armor clamping cone and ring are used for tightening the cable’s metal so as to establish a robust metal-to-metal contact. Finally, the sealing washer is important as it determines the number of entry holes for your cable.

It also determines the ingress protection (IP) rating of your cable gland. It is the primary part of your multiple cable gland.

You’ll also find out that multiple cable glands come in different sizes. The reason why they are made in different sizes is primarily to handle the differences in size for your cables.

The material used to make these multiple cable glands are also different. You’ll find that there are brass, stainless steel, and nylon multiple cable glands in the market today.

You can also consider the type of thread used to make these multiple cable glands. You can find either Metric, NPT, or PG threads.

Q6. How Should I Connect My Multiple Cable Glands On Cables?

Connecting your multiple cable gland is not a difficult process. It is pretty straightforward. You’ll only need to know where you want your cables to pass through. For example, if you want your cables to go into an electric box, you can start by drilling a hole that shares the same diameter as the cable gland.

Check out this short video to see how you can install a multiple cable gland. It’ll show you the different parts of a multiple entry cable gland.

Q7. What Are The Benefits Of Using Multiple Cable Glands?

It’s true that:

Multiple cable glands have a ton of benefits. You can distinguish their benefits based on three criteria:

• General benefits for all multiple cable glands
• Benefits based on specific materials used to make these multiple cable glands
• Type of thread used by each multiple cable gland

●    General Benefits

The first general benefit of using any multiple cable gland is protection from environmental contaminants. These contaminants include water, dust, moisture, dirt (sand), etc.

Cable glands, in general, prevent these contaminants from reaching your cable’s connection points.

The second benefit is that multiple cable glands provide multi-entry cables capability. They have more than one entry hole in their seals. There can be at least two entry holes for multiple cable glands.

You can also have differently-sized holes custom-made to meet your unique requirements.

The third benefit is that multiple cable glands provide your cable with strain relief. Strain relief means that your cables will not face exorbitant amounts of stress, especially if there are parts of it (the cable) that bend.

The fourth advantage is that some multiple cable glands provide vibration protection for their cables.

●    Specific Benefits

○     Brass Multiple Cable Gland

Brass multiple cable glands have high anti-corrosive properties, which enable them to function exceptionally well. They are also hardy.

In other words:

Brass multiple cable glands can serve you longer under extremely difficult conditions. They have a longer lifespan compared to nylon multiple cable glands.

The second benefit of using a brass multiple cable gland is that they are explosion-proof. Unlike other kinds of multiple cable glands, brass multiple cable glands can withstand high temperatures.

Brass multiple cable glands have a working temperature of -40°C to temperatures slightly above 100°C. This feature makes them suitable for use in electric, signaling, and probing cables.

○     Stainless Steel Multiple Cable Gland

The first reason is that stainless steel is hardy. It can survive the harshest environmental hardships, meaning that it can be used anywhere. It is highly stable and durable because of its anti-corrosive surface.

The second benefit is that they provide excellent performance. They can work in temperatures as low as -40°C to temperatures slightly above 100°C.

The third benefit of using stainless steel multiple cable glands is that they offer your cables strain relief. Strain relief is particularly important when your cables bend or when they are tightly held.

It’ll also help you when your cables keep on frequently moving, e.g., on a vibratory surface.

The fourth benefit of this cable gland is that it is cost-efficient compared to brass multiple cable glands. They are cheaper.

○     Nylon Multiple Cable Gland

The first benefit is that nylon multiple cable glands are cheaper. They are cheaper than both stainless steel and brass multiple cable glands. These nylon multiple cable glands are also reliable.

Nylon multiple cable glands also have a working temperature from as low as -40°C to temperatures slightly above 100°C.

Bottom line:

Multiple cable glands are highly beneficial in terminating the ends of your cables.

Q8. How Can I Select The Best Multiple Cable Gland For My Cable?

You need to select the ideal multiple cable gland for your cables. There are some questions that you’ll need to ask yourself so that you can acquire the best multiple cable gland for your cables.

Check them out:

The first criteria that you’ll need to rely primarily on the environment. Will you use the cable glands indoors or outdoors? What is the expected environment? (Safe, hazardous, explosive, etc.)

What does the surrounding area look like? Is it dusty or moist?

The above questions will help you decide the ideal material to use for your multiple cable gland for your cable. It’ll also help you know the IP rating that you’ll require.

Then, the second primary criterion that you’ll have to consider yet again is the structure of your cable. You can ask yourself the following question:

Is my cable armored or unarmored? Here’s how you can know whether your cable is armored or unarmored:

An armored cable has an extra layer of protection, mostly made from steel. These types of cables are highly used in areas where they are exposed to mechanical damages.

You can also know if your cable is unarmored by looking at its structure. It has a rather basic structure compared to the armored cable.

In other words:

An unarmored cable does not have an extra layer of protection. They are mostly used in areas with minimal mechanical damage.

You’ll then need to consider the third primary criteria – the sizes of your cables. Your cable size determines the diameter of the entry holes for the multiple cable gland you’ll order.

You’ll also need to consider other factors such as extra protection features, for example, vibration protection, fire protection, etc. You’ll also need to consider the type of thread to use on your cable. You can opt to use either metric, Panzer Gewinde (PG), or NPT threads.

Metric threads are usually straight. NPT threads seal your cable ends with substantial pressure and rigidity. The PG thread is a bit different –  it has smaller threads compared to both the NPT and Metric threads but has a wider pitch because of its large flank angle.

Q9. Which Multiple Cable Gland Should I Use For My Armored Cables?

Armored cables are ideally made up of thick steel wires meshed underneath the outer PVC layer. These cables are designed to work in the most stressful and harsh environments. Some manufacturers opt to use aluminum meshing as opposed to using steel meshing.

                                                                   Figure 5: Armored Cable

Check this out:

You can choose to use brass multiple cable glands for your armored cable. Brass multiple cable glands are ideal for glanding armored cables. Its features are what make it a suitable candidate for the termination of armored cables.

Brass cable glands with multiple entry holes are easy to install. They are also hardy, meaning that they can withstand harsh environments. They further prevent the entry of contaminants into your armored cable connection. They also do not corrode quickly.

You may also opt to use nickel-plated brass multiple cable glands.

You can also use stainless steel multiple entry cable glands to terminate the ends of your armored cable. Stainless steel is also hardy, and its surface is designed to prevent rapid corrosion.

Q10. Which Multiple Cable Gland Should I Use For My Unarmored Cables?

When glanding your unarmored cables, you can use three types of multiple entry cable glands.

Figure 6: Unarmored Cable

You can use either the nylon, brass, or stainless steel multiple cable glands for your cables. Unarmored cables do not have an extra layer of protection against mechanical damages. This, therefore, means that you can use any type of multiple cable gland for your cables.

You’ll need to know which multiple cable glands to use depending on the environment in which your cable will pass through.

Q11. How Can I Calculate The Size Of My Multiple Cable Gland?

Now, it is true that:

The calculation of your multiple cable glands size can be intimidating. Why?

Different people have different cable glands requirements. For example, you may want to gland cables that are not equal in size (diameter) using a single multiple entry cable gland. This difference means that some entry holes will be bigger than others.

Here’s the deal:

Multiple entry cable glands are extremely dynamic. You’ll need to contact a reputable multiple cable gland manufacturer to get your multi-entry cable glands specifications.

Q12. What Is The Ideal Working Temperature Of A Multiple Cable Gland?

Typical multiple cable glands have a working temperature of -40°C to temperatures slightly above 100°C. This temperature range is applicable for nylon, brass, and stainless steel multiple cable glands.

Now, there are times you may have unique requirements – you’ll definitely need multiple cable glands that can withstand extremely low temperatures. On the contrary, you may also need multiple cable glands that can withstand exorbitant amounts of heat.

You can have special multiple entry cable glands that can withstand temperatures lower than -40°C and can also withstand temperatures higher than 100°C.

You’ll need to put into consideration the estimated amount of temperature your cable gland will be subjected to as it works.

Q13. What Type Of Threads Do Multiple Cables Use?

Multiple entry cable glands use three different types of threads:

• Metric Thread
• NPT Thread
• Panzer Gewinde (PG) Thread

Here’s how the three threads differ from each other:

Metric threads are usually straight. You’ll find cable glands using the metric thread inscribed, e.g. M12 x 1.5. The M stands for Metric (the thread type) while the 12 stands for diameter in mm and the 1.5 stands for pitch in mm.

NPT threads seal the ends of your cable with a lot of rigidity and pressure. This type of thread is suitable for the prevention of entry of contaminants that can damage the ends of your cable.

The final thread type is the Panzer Gewinde. It originated from Germany. It has smaller threads compared to both the NPT and Metric threads but has a wider pitch because of its large flank angle.

Apart from thread type, consider also the thread length. The length of your thread matters a lot, especially if your cables are to pass through an object (like a thick wall).

Q14. Do Multiple Cable Glands Offer Vibration Protection?

Yes.

Multiple cable glands can have the special feature that offers you vibration protection. You’ll find this feature most useful when it comes to fixing your cable on a vibratory surface.

Q15. Do Multiple Cable Glands Protect Your Cables From Fire?

Yes.

There are multiple cable glands that are fireproof. You can order this special depending on your requirements.

Check this out:

When a multiple cable gland is fireproof, it offers other services that are generally considered fire performance cable glands.

Fire performance includes fire survival, flame redundancy, smoke emissions, and fire resistance.

Bottom line:

You can order multiple cable glands today that will help you prevent fires. You’ll only need to specify that when ordering them from your manufacturer.

Q16. How Well Do Multiple Cable Glands Protect My Cable From Water And Moisture?

All cable glands, in general, protect your cables’ ends from water and moisture. However, all of them do not have the same contaminant entry protection rating.

Check this out:

All cable glands, including multiple cable glands, have an IP rating which protects your cables’ ends from contaminants such as water, moisture, dust, dirt, etc. IP rating (Ingress Protection) is the level or degree of sealing cable glands provided to the cable ends they terminate.

Here is how IP ratings work:

Suppose you have a multiple cable gland with an IP68 rating. The 6 in 68 means the level of intrusion protection. It is the level of protection the cable gland offers you against the entry of weak water jets. However, it does have a specified level of protection against solid particles.

On the other hand, the second value in IP68, that is, 8, shows the level of partial protection against dust. It, however, does not specify the level of protection against moisture.

Rayphen’s multiple cable glands have a standard rating of IP68. This means that they have a significant amount of protection from fluids, dust and dirt (e.g. sand particles).

Protecting your cables’ ends from the entry of contaminants increases its service life. It’s therefore imperative for you to carefully understand the environment from which your cable will stay. Once you understand its environment, you can then make an informed decision on which multiple cable gland IP rating you’ll require.

Q17. Which Type Of Seals Do Multiple Cable Glands Use?

Multiple cable glands seals are one of the most vital elements. The multiple gland seal contains multiple holes – which enable you to insert several cables simultaneously through a single cable gland.

Now, your multiple cable gland seals are made from synthetic polymers. These seals prevent the intrusion of contaminants and enhance the performance of the multiple cable gland. The seal is temperature resistant and has excellent compression properties.

Q18. Where Are Multiple Cable Glands Used?

Multiple cable glands have lots of uses – you should not underestimate their importance. They are used in different professional fields.

Multiple cable glands are mainly used in electrical power control, telecommunications and data control, as well as instrumentation.

Q19. Can Multiple Cable Glands Be Repaired?

It’s not advisable to repair your multiple cable glands. Once they get damaged, they’ll require urgent replacement.

You can attempt to repair them, but their performance will not be as effective and efficient as it was when the multiple cable gland was new. They may tend to leak contaminants into your cables’ connections.

Bottom line:

Repairing spoilt parts of your multiple cable glands does not permanently solve the problem. You’ll eventually need to replace the spoilt ones with the new ones.

Q20. What Are The Benefits Of Using Brass Multiple Cable Glands?

Brass multiple cable glands have high anti-corrosive surfaces.

                                                       Figure 6: Brass Multiple Cable Gland

This means that:

Brass multiple cable glands can serve you longer under extremely difficult conditions.

Brass multiple cable glands are also hardy, meaning that they have a longer lifespan compared to nylon multiple cable glands. You’ll find the most useful in areas with high risks of mechanical damage.

The second benefit of using a brass multiple cable gland is that they are explosion-proof. They can contain cable explosions, even when they are under high temperature.

The third benefit of using brass multiple cable glands is that it has a wide usage. You can easily find them and replace them.

It also shares its benefits with other multiple cable glands, which include:

• Protection from environmental contaminants, which include water, dust, moisture, dirt (sand), etc.
• Multiple cable glands provide your cable with strain relief.

Q21. What Are The Benefits Of Using Nylon Multiple Cable Glands?

Nylon cable glands are highly beneficial. They help you terminate the ends of your cables well.

Figure 8: Nylon Multiple Cable Gland

Check out their benefits:

The first benefit nylon multiple cable glands have is that they protect your cable from the entry of contaminants. They’ll ensure that your cables last longer.

The second benefit is that they have an operating temperature of -40°C to temperatures slightly above 100°C. This means that they can work in almost any environment without failing.

The third benefit is that they can be used in control cabinets, machines, etc., where they’ll be exposed to harsh working conditions. In other words, they are hardy.

They are also cost-effective – they are not expensive compared to stainless steel and brass multiple cable glands.
