Keyword: Optical fiber composite overhead ground wire OPGW-central bundle tube
Product Description
Product Description
Optical fiber composite overhead ground wire (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 mainly used for communication lines of 110KV, 220KV, 500KV, 750KV and new overhead high voltage transmission system. It can also be used to replace the existing ground wire of the old overhead high-voltage transmission system, increase optical communication lines, conduct short-circuit current and provide anti-lightning protection. Special structure can be customized according to user needs.
Product Features
Stainless steel tube to protect the optical fiber, high tensile strength;
Small cable diameter, light weight, low additional load on the tower;
· The optical unit forms a suitable primary fiber excess length;
· Stretch resistance, torsion resistance and lateral pressure resistance are slightly worse.
