OPGW fiber optic composite overhead ground wire (central bundle tube type)

Product Model：

OPGW-central bundle tube type

Optical fiber composite overhead ground wire (OPGW) is an overhead ground wire with optical fiber, which has multiple functions such as overhead ground wire and optical communication, and is mainly used for communication lines of 110kV, 220kV, 500kV, 750kV and new overhead high-voltage Electric power transmission. It can also be used to replace the existing ground wire of the old overhead high-voltage Electric power transmission, add optical communication lines, conduct short circuit current and provide lightning protection. Special structures can be customized according to user needs.

Product Description

Product Description

Product Features

1. Adopting advanced stainless steel pipe production technology, the pipes are filled with water blocking compounds

2. Short circuit current has little mutual interference between the power grid and communication network

3. The excess length of the optical fiber and the pitch of the cable core stranding ensure that the optical cable is not subjected to force during maximum operating tension

4. Compact structure with high tensile strength

5. Similar to the specifications of commonly used ground wires, it is very convenient to install and can directly replace the original ground wire
