Uni-fibercable offers a complete portfolio of fiber optic cable, supporting hardware and compression accessories that are designed to meet the most demanding transmission and distribution environments. As the leading world manufacturer of fiber optic cable, Uni-fibercable is uniquely positioned to provide a full line of all-dielectric self-supporting (ADSS) aerial cables and Optical Ground Wire (OPGW) as well as supporting hardware and accessories.
For transmission application, we provide entire cable solution including OPGW, ADSS, OFC. We have projects experience in 132kv, 220kv, 400kv & 765kV.
OPGW fiber optic cable is mainly used on 500KV, 220KV, 110KV voltage grade lines. It is affected by factors such as power outage and safety of the line, and is mostly applied on new lines.
The applicable features of the OPGW are:
- Lines with a high voltage exceeding 110kv, the span distance is large (generally more than 250M);
- It is easy to maintain, easy to solve the problem of line crossing, and its mechanical characteristics can meet the big leap of the line;
- The outer layer of OPGW is metal armor, which has no effect on high voltage erosion and degradation;
- OPGW must be powered off during construction, and the loss of power outage is large. Therefore, OPGW should be used in the new high-voltage line above 110kv.
- In the performance index of OPGW, the larger the short-circuit current, the more it needs to be armored with good conductor. The tensile strength is correspondingly reduced, and in the case of a certain tensile strength, the short-circuit current capacity is increased, and only the cross-sectional area of the metal is increased, thereby causing an increase in cable diameter and cable weight, thus posing a safety problem for the strength of the line tower.
Uni-fibercable aims to play a significant role in reliable power-line communication network, long-haul transmission for power grid communication, power distribution automation, electric power information collection and energy resource access and cater to the needs of electric power transmission and distribution networks.
