  OPGW (optical ground wire) is used in the transmission line for surge communication and protection. In recent years, OPGW has replaced Power-line carrier communication (PLCC). Usually, OPGW is placed in the topmost secured position of any transmission line, where OPGW protects every important conductor against lighting. There are a number of OPGW fittings available in the market. Read the blog to explore more about OPGW.   What is OPGW?   The optical ground wire which is also called OPGW is a kind of cable which is used in the overhead power lines. These cables merge both the functions of communications and grounding. The OPGW cable consists of a tubular structure along with either one or more optical fibers inside it. OPGW cables are enclosed with layers of aluminium and steel wire. OPGW cables run in between the high voltage electricity pylons. OPGW cables' conductive part helps in bonding abutting towers to the earth ground and protects HV conductors against lighting
