A compression cable gland could simply be described as “a mechanical access device”. Putting the simple definition aside, the compression cable gland could be given the general description as a device that is used to form an attachment to the terminal of an electric cable to secure its connection to the targeted equipment.
In essence, compression cable glands are also referred to as compression cable connectors, compression strain fittings, compression cord grips, or compression cable fittings. They are majorly used in cables with diameters ranging between 1milimeter and 75 millimeters. Similarly, compression cable glands have the ability to:
- Initiate electrical connectivity to the braid and aluminum sheath of a cable
- Avail strain relief in electric cable connections
- Provide strain relief in cable-device connections
Q2. How Does A Compression Cable Gland Work?
Figure 2: The Working mechanism of a compression cable gland
It is easy to know how a compression cable gland works by understanding its structural mechanisms first. In essence, a compression cable gland is made by initiating a structural combination of a central body/enclosure that will allow the passage of the necessary cabling with a range of attachments.
A typical compression cable gland will come as a typical lock nut with washers, an attachment cone (or claw), and an outer compression (or sealing) nut. In other cases, some manufacturers will present models that come with two-part enclosures, insulation, and a tag for electrical earthing.
Looking at the parts outlined, compression cable glands may work in diverse applications for operations like:
- Electrical earthing- Your compression cable glands could be highly effective in withstanding any form of peak sort and circuit fault currents.
- Strain relief- The compression cable gland works to ensure that only the recommended level of strain is allowed.
- Additional sealing- your compression cable glands will offer an additional layer of sealing in electrical connections that need optimal ingress protections.
- Electrical grounding
- Electricity insulation
- Electricity bonding
Similarly, compression cable glands have the structural ability to repel and cushion your cables from external contaminants like electrical sparks, flames, fluids, clouds of dust, and other forms of dirt at the junction connecting the cable to the targeted electrical device.
Here’s the summary of the principal functions of compression cable glands:
- Compression cable glands may come in handy when there’s a need to fix cables in place and offer protection against mechanical twisting effects and accidental pullouts from the targeted electrical devices.
- Fortification of cables against mechanical strains
- Provision of airtight seals that will help keep out external agents like dust, moisture, water, and dust particles.
- Offering the vulnerable ends of the connected cable from damages
- In other instances, compression cable glands could be useful in operations that require earthing electrical cables and help in cutting the risks of electrocutions and electric shocks.
Ultimately, the major role of compression cable glands is to stop your cables from the pulling and twisting interferences that are manifested when individuals interact with electric devices. This is essential because of their ability to avail of a safe and stable connection between the electric device and the cable.
Q3. What Are the Different Elements of a Compression Cable Gland?

You may use your compression cable glands in an array of settings (earthing, train relief, grounding, bonding, and insulation). In particular, your compression cable glands are essentially meant for use in cable management practices. They are designed to secure and attach an electric cable with an electric device. You may also use compression cable glands to offer sealing for cables that penetrate through the bulkheads of the associated gland plates.
In some cases, compression cable glands will be used in hazardous and harsh environments to offer protection against electric sparks and repulsion of outside contaminants. In addition, these glands are very effective in offering continual performances in electric cables.
Q 9. Why Is Compression Cable Gland Earthing Required?
Have you ever suffered the effects of an electric shock when touching a connected electric device? Well, this could have been caused by a faulty electrical installation procedure that led to the exposure of a live metallic part. As such, the electric current took advantage of your body to form a path from the live area of the connection to the earthing location.
Earthing in compression cable glands offers protection against any forms of electric shocks that may result from exposures to cables. Your compression cable gland will initiate such protections by availing a path that will allow for the effective passage of fault current to earth. It may also cause the circuit breaker of the targeted electric device to switch off any electric current that is at fault.
Q10. Are Compression Cable Glands Waterproof?
Figure 9: Waterproof compression cable glands
Yes, some compression cable glands are custom-made to offer their waterproofing attributes among the targeted consumer segments. In particular, waterproof compression cable glands are meant to be used in connecting wires inside electronic enclosures that require effective maintenance of watertight seals in areas where the cable enters an insertion.
In most cases, waterproof compression cable glands will comprise a nut, a body, a cable seal, and a separate gasket. All these components are meant to be integrated into the compression cable gland’s body. In essence, a waterproof compression cable gland is assembled inside a circular cutout of the enclosure to capture the enclosure’s wall between the nut and the body. This creates a watertight sealing.
Q11. How Do I Fit A Compression Cable Gland?
You needn’t find a lot of problems the next time you want you’re sent of compression cable glands installed. The installation process is very easy and straight forward unlike other types of electric assemblies. Here’s the ten-step process that will come in handy the next time you want to install your set of compression cable glands:
Step 1: Decide on the type of steel used in the cable you want to fit.
- How many cores does the cable have?
- Have a clear determination of the exact size of the cable
Step 2: Review the gland pack
It is highly significant to check the compression cable gland packing before you start the installation process. This gives you the confidence that whatever you have is the gland that befits the cable of choice. Just ensure that the gland matches the actual cable you have adopted. Your gland pack will usually comprise of a pair of:
- Earthing rings
- Locking nuts
- Gland bodies
- Gland nuts
Step 3: Get the required length of cable
Measuring the length of the cable needed for the installation process should come first before initiating the termination exercise. You’ll only need to use tape to mark the point where the cable should be cut.
Step 4: Fit the veil
This is where the real fitting process starts. It is at this point that you insert the shroud and insert it inside the end of the cable. Be keen to ensure that it is nice and firmly pulled.
Go forth and cut around the top while ensuring that the shroud maintains a proper fit with the SWA cable. Slide the gland down to the cable after initiating the cut.
Step 5: Trim the cable
A junior hacksaw could be the best tool to use when cutting the cable at the region around the top of the tape you had used earlier. Just ensure that you follow the tape line the best you can when cutting. Do this with a lot of keenness not to damage the inside of the conductor.
Step 6: Eradicate the PVC
Use a knife to wind off the outer PVC covering by holding the cable firmly and running the knife along its length then remove it all.
Step 7: Take time to unwind all the wires outside the cable.
You may achieve this by giving the wire a gentle back and forth rock after the cord is unwound.
Step 8: Fix the gland nut
Here, you need to ensure that the threads of the gland are pointing outwards and analyze the length of the PVC that must be removed to ensure that the SWA is exposed. Be keen to ensure that only enough of the PVC is extracted and not more. Cutting about 10 centimeters below the tapped region could help.
Step 9: Insert the compression cable gland in the cable while ensuring that the serrated edge is down
You need to ensure that the thimble section of the compression cable gland drops inside the cable without moving beyond the thread then wind the body of the gland with open gland nuts. This is the time to drop the gland below the SWA. However, you need to ensure that the attachment presents a firm rotation.
Step 10: Tightening
The gland will work effectively when it is tightly fitted into the cable. You’ll only need two spanners to tighten the compression cable gland as required. The first spanner will be used on the actual nut and the other on the gland’s body. You will get the best results by trying to back it up and twisting the gland’s nut as a way of tightening it inside the body. Though you may use adjustable grips in this exercise, they may not avail the required results as they will shave off the parts of the body made of brass in the future.
Step 11: Remove the outer PVC on the cable and add an earthing ring to the resulting enclosure. However, you need to be keen to ensure that none of the steel wires in the cable have crossed over or missed underneath.
The compression cable gland is now set, tight, and ready to use.
Q13. What Are the Different Types of Cables and Compression Cable Glands to Be Used?
Multiple types of cables may be applied in compression cable glands. However, the classification of these cables greatly depends on the following characteristics:
