OPGW Typical Designs of Central AL-covered Stainless Steel Tube
Optical Ground Wire (OPGW) Mainly used for power communication with accessories, relay protection, automatic transmission, installation together with high-voltage lines. 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.
