1.zinc clad steel grounding in special steel for the steel core, with the strength of steel and thermal stability, ensure the grounding of the discharge function.

2. zinc as a coating metal, its conductivity is 2.5 times that of steel, it greatly increased electrical conductivity. Zinc as the metal coating has strong corrosion resistance and service life greatly extended.

3.due to a certain thickness of the layer of zinc as sacrificial anode, so the device can protect the earth, underground metal and related equipment, iron and steel without any corrosion.

4.the use of special manufacturing process to form a double metal composite material, so has good plasticity, to ensure coverage during the construction and application of zinc coating will not fall off.
