OPGW optical fiber cable

Product features: It has dual functions of ground wire and communication cable, which eliminates the huge cost of repeated erection and maintenance. Installed on the top of the electric overhead line tower, without considering the best hanging point and electrical corrosion and other factors;

Product Detail

Product Model: OPGW
Should use:
OPGW optical cable is mainly used in 500KV, 220KV, 110KV voltage grade lines, affected by line power failure, safety and other factors, mostly used in new lines. The applicable characteristics of OPGW are:
☆. High voltage more than 110kV line, file distance is larger (generally more than 250M); 
☆. Easy to maintain, easy to solve the problem of line crossing, its mechanical characteristics can meet the big line crossing; 
★.OPGW outer metal armored, high voltage corrosion and degradation has no effect; 
☆.OPGW must be cut off during construction, and the loss of power failure is large, so OPGW should be used in the new high voltage lines above 110kV; 
☆.OPGW performance indicators, the greater the short-circuit current, the more need to use good conductor armor, the corresponding reduction of tensile strength, and in the case of a certain tensile strength, to improve the short-circuit current capacity, only increase the metal cross-sectional area, resulting in cable diameter and cable weight increase, so the strength of the line tower put forward a safety problem.

Points:
☆. Both ground wire and communication cable dual functions, eliminating the huge cost of repeated erection and maintenance;
☆. Installed on the top of the electric overhead line tower, without considering the best hanging point and electrical corrosion and other factors;
☆. In the process of transformation of the old line, the outer diameter of the cable and the single weight of the tension is better than another ground wire to match;
☆. Large transmission capacity, high communication quality, good reliability;
☆. Excellent mechanical and electrical properties;
☆. Good safety performance, long service life, not easy to be destructive shooting.
