OPGW OVERHEAD GROUND WIRE
Overhead Optical Ground Wire Description:
The Aluminum tube is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires. Good anti-corrosion performance. Material and structure are uniform, good resistance to vibration fatigue.
Optical Ground Wire Description:
The central Al-covered steel tube is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires. Al-covered Stainless Steel tube design increases the cross section of AL, to reach a better fault current and lightning resistance performance. Apply to the transmission line which requires small diameter and large fault current.
