Copper-bonded wire (D8 and D10 mm)

Product item: GL-11149 / GL-11150

Copper-bonded wire is made of rolled steel with electrolytic copper plating with a purity of 99.9% and not less than 0.070 mm thick, that forms molecular and indissoluble connection with the steel.

T​​​​​he wire with the diameter of 8 mm (cross-sectional area of 50 mm²) is used as shunts or mesh lightning rods.

The wire with the diameter of 10 mm (cross-sectional area of 80 mm²) is used as horizontal grounding electrode / grounding conductor.

For interconnecting and for connection to grounding electrodes, stainless steel clamps are usually used

(e.g. GL-10332N or GL-11551A).

Copper-bonded wire (D8 and D10 mm)

Why is the thickness of the copper coating of a ground pin is 250 microns, while the thickness of the coating of a ground conductor is only 70 microns?

The minimum thickness of the copper coating of ground pins of 250 microns is related to the installation method of these pins. In the process of burying the protective coating is subject to high mechanical stresses when contacting the surrounding soil (e.g., small stones). These stresses lead to the partial loss of the coating up to 150 mm thick (in particular, rare cases).

In such extreme conditions - after burial of pins, the corrosion-resistant copper coating will be not less than 100 mm, which is sufficient for a very long service life of the ground electrode.

For copper-bonded conductors, the copper coating of 70 microns is effective and technically justified because the conductor fits into preformed trenches and therefore is almost not subjected to mechanical stress. Thus, such coating thickness (70 microns) is sufficient to maintain its anti-corrosion properties for a long period of time, comparable to the service life of copper-bonded ground pins.
