Product Details
OPGW fiber optic cable is the short form of Optical Fiber Composite Overhead Ground Wire. OPGW fiber optic cable is suitable for installation on new power lines with double function of ground wire and communication. Especially for installation on normal voltage and extra high voltage power lines. OPGW cable can replace conventional ground wire of old power line with increasing fiber communication function. OPGW cable conduct short circuit current and provide lightning resistance.
OPGW Fiber Optic Cable with IEEE1138 Standard (Model: OPGW) Structure:
Stainless steel loose tube
The stainless steel loose tube, ACS and outside AA can be stranded to form the single layer. It is coated with anti-corrosion jelly between the stranding layers
OPGW Cable Features:
(1) The OPGW fiber optic cable uses stainless steel loose tube structure, increasing its reliability and the performance of temperature-resistant.
(2) The OPGW fiber optic cable meets the requirement of large fiber line application.
(3) The OPGW fiber optic cable is specially applied for the optical communication system while installing the electric transmission line.
(4) Project design (sag-tension calculation, short circuit current, ADSS hardware fittings calculation)
Application:
.OPGW fiber optic cable is mainly used in 500KV, 220KV and 110KV lines, limited by power cut, security and other elements, mostly used in new lines. Its applications are: high voltage over 110kv, with a longer span (usually over 250M);
.easy to maintain, easy for line span, its mechanical property can meet a big line span;
.outer OPGW fiber optic cable is metal armoring, with no influence for high pressure electro-corrosion and degradation;
.to construct OPGW fiber optic cable must cut power, resulting in greater loss, thus OPGW must be used in constructing high voltage line over 110kv;
.For OPGW fiber optic cable performance index, the more short circuit current, the more need a good conductor to be metal armor, and reduce tension strength, while, if the tension strength is certain, to increase short circuit current capacity, the only way is to enlarge metal section area, resulting in an increased cable Dia and weight, so that security is a question for line pole strength
