19 Strands 9AWG Hard-drawn Copper Clad Steel Copperweld Wire 40% Conductivity for Earthing System
Copper Clad Steel (CCS) strand wire as the grounding conductor for primary surge arresters permits a continuous length of conductor to be installed from the arrester to the buried grounding electrode. This is a practice which is not usually recommended with
aluminum conductors. The steel core of the strand wire provides a rugged lead. It can withstand more mechanical abuse and is less susceptible to vibration-induced fatigue than solid copper or aluminum wire. When wire is used in place of copper, the grounding conductor is far less likely to be stolen. This feature is important not only from an economic standpoint, but also from the standpoint of safety and reliability. Often, the fact that a copper downlead has been removed is not evident until a surge current causes a failure in the system.
ASTM B228, ASTM B229, ASTM B910, ASTM B452 and ect. Construction:
* Concentric-lay stranded.
* Core wires or central wires are helically surrounded by outer layer wires, the direction is reversed compared with successive layers.
* Popular Copper Clad Steel Wire Strands 7, 19, 37
