Shield Wires:
The phenomenon of lightning can potentially cause damage to power transmission lines. The damages inflicted upon these lines can be undesirable and costly, as replacing the conductors imposes a substantial financial burden on responsible companies. To prevent such damages, one can employ a steel static shield wire an overhead electrical wire designed to protect power transmission lines from lightning strikes.
OPGW:
An Optical Ground Wire (OPGW) is a type of overhead shield wire that contains optical fibers. These optical fibers are enclosed within aluminium or stainless-steel tubes, with a specific number of fibers per tube.
Shield Wire GA
Shield wires with galvanized core are suitable electrical shields that protect overhead power transmission lines. These wires are made of steel strands with galvanized coating and exhibit good corrosion resistance.
Shield Wire AW
Shield wires with aluminum-clad steel wires used as static shields in overhead transmission lines have improved corrosion resistance and longer lifespan due to the use of aluminum coating (AW).
Optical Ground Wire
The Optical Ground Wire, cable is used in energy transmission lines to protect the phase wire against instantaneous lightning currents at the highest point of the tower and transmits transient currents to the ground through the earth wire of the tower. Another important task of this wire is the transmission of audio and video data using optical fibers.
