Optical Ground Wire (OPGW) Cable

Optical Ground Wire (OPGW) Cable

OPGW or known as Optical Ground Wire is a type of cable or wire that is used in transmission lines construction. It is also known as optical fiber composite overhead ground wire. It can serve as a grounding wire, shielding wire, and at the same time a cable used for communication purposes.

OPGW contains a tubular structure with one or more optical fibers in it. It is then surrounded by layers of steel and aluminum wire. It can be compared like an ASCR, except that steel is the one covering the tube with fiber optics inside.

OPGW have the characteristic that there is no effect of high voltage induction on the data being transmitted through the Fibers. Hence this characteristic of the Fiber is taken into advantage to transmit the data along the high power transmission lines.

Application
OPGW have the characteristic that there is no effect of high voltage induction on the data being transmitted through the Fibers. Hence this characteristic of the Fiber is taken into advantage to transmit the data along the high power transmission lines.

OPGW cable is run, or installed between the tops of high-voltage electricity pylons, steel, wood, or concrete poles with appropriate fittings and attachments. The conductive part of the cable, in this case the steel serves to bond adjacent towers to earth ground, and shields the high-voltage conductors from lightning strikes.

OPGW

Feature
1. Relatively low cost solution to provide Communication and Data backbone trunks.
2. No needto acquire land to lay down the fiber optic cable since Power Transmission Company has right of
way for its towers.
3. No digging, trenching, filling etc. is required as the cable is laid high in the air and not underground. This is
especially advantageous in hilly, marshy, rocky terrain.
4. The cable is not damaged by human or animal actions as it is out of reach of both of them.
5. The cable is well protected by a bundle of strong steel or aluminum conductors.
