The Role of Optical Cables in Overhead Power Transmission Lines
The purpose of an OPGW cable is twofold: Firstly, it protects power lines from lightning strikes by acting as the shield wire at the top of the transmission tower. Besides traditional cables lashed to messengers, figure-8 cables or ADSS cables, utilities can construct transmission links using optical ground wire (OPGW) or optical power phase conductor (OPPC). Optical attached cable (OPAC) is a type of fibre-optic cable that is installed by being attached to a host conductor along overhead power lines. The attachment system varies and can include wrapping, lashing or clipping the fibre-optic cable to the host. ❓ Q1: What is an OPGW Cable? A: OPGW (Optical Ground Wire) is a power transmission cable featuring.
