Quick Details
Product Details
Description:
OPGW cable is the short form of Optical Fiber Composite Overhead Ground Wire. OPGW 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 Cable 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 uses stainless steel loose tube structure, increasing its reliability and the performance of temperature-resistant.
(2) The OPGW meets the requirement of large fiber line application.
(3) The OPGW are 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)
