Product Description:OPGW cable is the short form of Optical Fiber Composite Overhead Ground Wire. OPGW cable is suit 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 can replace conventional ground wire of old power lines with increasing fiber communications function. OPGW cables conduct short circuit current and provide lighting resistance.OPGW cables are usually two structures. The central tube OPGW cable can obtain maximum optical fiber excess length in a smallest steel tube. The diameter of stainless steel tube is bigger than that of ACSR wire and aluminum alloy wire. The stainless steel tube is placed in the center of the stranded structure of the OPGW cable. Stranded OPGW cable can obtain secondary excess length; the diameter of stainless steel tube is consistent with diameter of aluminum alloy wire.Application:Optical fiber composite ground wire [OPGW] is suitable for installation on new power lines with double function of ground wire and communication. Especially for installation on normal voitage and extra high voltage power lines. OPGW can replace conventional ground wire of old power line with increasing fiber communication function. They conduct short circuit current and provide lightning resistance.Features:1. Up to 144 fibers2. Cable diameter and weight approximate with another ground wire. Less additional load to tower, high tensile strength.3. Excellent stainless steel tube stranding technology make the fibers have good secondary excess length and allow the fibers free movement in the tube. Which keeps the fiber stress-free while the cable is subjected to longitudinal stress.4. Optical fibers are protected by stainless steel tubes.5. Excellent security, good bullet resist performance.6. ACSW, AAW and SST stranded design provide wide range combination of electrical conductivity and mechanical tensile strength.ItemsOPGW CABLEStructureStainless steel loose tubeFeatureThe OPGW uses stainless steel loose tube structure, increasing its reliability and the performance of temperature-resistant.The OPGW meets the requirement of large fiber line application.The OPGW are specially applied for the optical communication system while installing the electric transmission line.Project design (sag-tension calculation, short circuit current, ADSS hardware fittings calculation)Excellent stainless steel tube stranding technology make the fibers have good secondary excess length and allow the fibers free movement in the tube. Which keeps the fiber stressfree while the cable is subjected to longitudinal stress.Cable diameter and weight approximate with another ground wire. Less additional load to tower, high tensile strength.ACSW, AAW and SST stranded design provide wide range combination of electrical conductivity and mechanical tensile strength.Till
now, TDDL has obtained a series of certifications covering ISO9001
