OPGW is a kind of overhead ground wire containing optical fiber, which has multiple functions such as overhead ground wire and optical communication. It is applicable to new aerial power route to satisfy the needs for big conductors and high voltage transmission, and is used to conduct large fault short circuit current to provide anti lightning protection. It is mainly used on 500KV, 220KV and 110KV voltage level lines. It is mostly used on new lines due to the influence of line power outage and safety.

Product feature
- The fiber is well protected by mechanical and thermodynamics.
- Excellent capability against side and outstanding short circuit current capacity.
- Optical fiber is not under stress when it is subject to the maximum permissible stress.
- Layer-stranded single wire provides excellent mechanical and electrical properties.
- Match with common ground wires.
Product applications
Replacement of aerial ground wire
Product structure
Extruding a layer of aluminum outside the PBT core to form an aluminum tube, the core is protected by a heat shield. This structure can reduce the electrochemical corrosion between different metal materials. It is often used for retrofitting old wirings, low voltage grade lines, and corrosive and highly polluted areas under coastal chemical environmental conditions.
- Small diameter and light weight, no additional load towers or poles required.
- Different color of loose tube, easy to distinguish multi-core OPGW and splice fiber.
Stainless steel optical unit is in the inner position. Compared with the central stainless steel tube, larger cable diameter and larger capacity of the optical fiber. It is applicable to new aerial power route to satisfy the needs for big conductors and high voltage transmission, and is used to conduct large fault short circuit current to provide anti lightning protection. Large diameter and large fiber capacity..
Product installation
- Aerial transmission tower
- Operating temperature -40ºC-+70ºC.
- Bending radius 25x cable diameter.
