NTOFC-OPGW-24-B1-42-54.0-9.3
1. Product Description:
OPGW Cable, Optical Fiber Composite Overhead Ground Wire, also known as Fiber Composite Overhead line. The optical fiber is placed in the
ground line of overhead high voltage transmission line and used to form the optical fiber communication network on the
transmission line. This structure has the double function of ground wire and communication, commonly known as OPGW optical cable.
1. Central Tube Optical Ground Wire (OPGW)
Description:
The Central Tube Optical Ground Wire (OPGW) is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires
and aluminum alloy wires. are the most widely used cables ,their design is fully adapted to the most common electric line needs.
