OPGW-24B1-90 OPGW cable manufacturer Price of opgw optical cable Opgw optical cable telephone
The full name of opgw optical cable is optical fiber composite overhead ground wire, which has both communication function and ground wire function. Ground wire is to avoid lightning strike, and communication is now used to transmit signals.
Features of OPGW power cable products
The design of OPGW power cable fully considers the actual situation of power lines and is applicable to any new high-voltage transmission line. We can carefully design matching products to meet the needs of users with different tensile strength, different short-circuit current and other parameters, so as to achieve the balance of mechanical and electrical performance.

Common OPGW power cable structures mainly fall into three categories: aluminum tube type, aluminum skeleton type and (stainless) Steel pipe Type.
Product application· opgw cable It is mainly used on 500KV, 220KV and 110KV voltage grade lines, and is mostly used on new lines due to power failure, safety and other factors. ·For lines with high voltage exceeding 110kV, the span is large (generally above 250M); ·Easy to maintain, easy to solve the problem of line crossing, and its mechanical characteristics can meet the requirements of large line crossing; ·The outer layer of OPGW is metal armored, which has no impact on high-voltage electric corrosion and degradation; ·During the construction of OPGW, power must be cut off, and the loss of power cut is large, so OPGW should be used in the new high-voltage lines above 110kv;
The presence of opgw is mainly used for the construction of new lines. It is widely used. Some old lines must be erected with ADSS optical cables, and ADSS must also be erected with lightning protection equipment, so it is cumbersome. In the future, opgw optical cables will be used for the erection of new lines, which will save time and cost.
The applicable characteristics of OPGW optical cable are: (1) For lines with high voltage exceeding 110kV, the span is large (generally above 250M); (2) Easy to maintain, easy to solve the problem of line crossing, and its mechanical characteristics can meet the requirements of large line crossing; (3) The outer layer of OPGW is metal armored, which has no impact on high-voltage electric corrosion and degradation; (4) During the construction of OPGW, power must be cut off, and the loss of power cut is large, so OPGW should be used in the new high-voltage lines above 110kv; (5) Among the performance indicators of OPGW, the higher the short circuit current, the more it needs to use good conductors for armouring, which will correspondingly reduce the tensile strength. When the tensile strength is certain, the only way to increase the short circuit current capacity is to increase the metal cross-sectional area, which will lead to the increase of cable diameter and cable weight, thus posing a safety problem for the strength of line towers. Other power cable products and accessories of Hebei Dazheng Company: OPGW cable, power cable fittings, adss cable, steel cored aluminum strand, overhead insulated conductor, steel strand, aluminum strand and other power cables.
