OPGW/Ground Wire

Ground Wire


Application: installation on medium and high-voltage power lines to protect phase conductors from direct lightning strikes
1

Central strength member (Aluminum Clad Steel wire)

2

Stranded wires (Aluminum-clad steel wires and /or aluminum alloy wires)

3

Stranded wires (Aluminum-clad steel wires and /or aluminum alloy wires)

Aluminum-clad steel wires are corrosion resistant

Mandatory element of 35 kV power lines approaching electrical substations and of all 110 kV power line

Aluminum alloy wires shield the high-voltage conductors from lightning strikes
