Copper C Clamps by Rayphen have a wide range of applications. They are used for transmission and distribution lines, high-speed rail, grounding electrode systems, photovoltaic, wind energy, as well as for 600V applications.

Q3. How do you use a Copper C Clamp?

  • Crimping type:

The pressure clamp equipped with a suitable crimping mold is used to put the wire into the groove of the corresponding ruler of the selected Copper C clamp.  An external force is applied to the pressure clamp to shrink the Copper C clamp and wrap it around the wire.

For crimping, high-quality hydraulic clamps are used. The hydraulic clamp has the ability to automatically release the pressure rapidly so that constant and uniform pressure can be applied during installation. Moreover, uneven construction, uneven physical strength, and quality of construction recruits can cause hidden damage. This damage is avoided by using hydraulic clamps.

  • Wedge articulated:

The hinge structure and the fixing element of the wedge clamp compress the wire between the clamp housing and the wedge. The fixing element overcomes the shortcomings of

multiple corrections are required by the nut sliding to the left and right sides when the screw is tightened. It also reduces the influence of human factors during installation.

The wire is not damaged during installation and disassembly; it can be reused many times.

Likewise, the clamp has a long life span, can reduce labor intensity, and improve work efficiency. It is an environmentally friendly and energy-saving tool.
