OPGW (Optical Fiber Composite Overhead Ground Wire) is a cable that serves both as a ground wire and for optical communication.
It’s mainly used in high-voltage transmission lines (such as 110KV, 220KV, and 500KV) and is ideal for new line installations.
The structure includes a stainless steel tube fiber unit, aluminum-clad steel wires (AS wires), and aluminum alloy wires (AA wires).

OPGW FIBER CABLE
Optical Fiber Composite Overhead Ground Wires are mainly used for power communication, relay protection, and automatic transmission, installed alongside high-voltage lines. The central stainless steel tube is surrounded by single or double layers of aluminum-clad steel wires (ACS) or a mix of ACS and aluminum alloy wires. These cables are widely used and designed to meet the most common electric line requirements.
