What Is OPGW Fiber?

OPGW, or OPTGW cables stand for Optical Ground Wire and they are a type of overhead fiber cable. OPGW are usually installed on normal voltage and extra high voltage power siberian mink eyelash. This type of cable has two functions: Ground Wire and providing a communication link for the transmission of voice, video or data by incorporating optic fibers into the cable. It is used in the construction of electric power transmission and distribution lines.

Thmne OPGW fiber cables are used to replace conventional ground wire of old power siberian mink eyelash with increasing fiber communications function.

:: The Structure of a OPGW Cable

An OPGW cable contains a tubular structure with one or more fibers in it, surrounded by layers of steel and aluminum wire.

:: Where is OPGW Cable Installed

The OPGW cable is installed between the tops of high-voltage electricity pylons. The conductive part of the cable serves to bond adjacent towers to earth ground, and shields the high-voltage conductors from lightning siberian mink eyelash. The optical fibers are used for transmission of data.

:: Advantages of OPGW Cable

Overhead optical fiber systems play a key role in telecommunications siberian mink eyelash. Due to the fact that no civil works are required and the rights of way have already been established, it is possible to minimize costs and, most importantly, the time required to begin network operation.

:: Other Types of Overhead Fiber Optic Cables

1) Self-supporting cables (ADSS). Self-supporting optical fiber system for all types of lines: electric lines, overhead distribution lines for railways, etc.

2) Lashed fiber optic cables. Optic fibers lashed to the ground wire or the phase cable on the electric siberian mink eyelash.

3) OPPC. Composite optical phase cables, for high voltage electric lines up to 135 kV.
