一、ADSS cable is loose tube stranded . Fibers, 250um , are positioned into a loose tube made of high modulus plastics .The tubes are filled with a water-resistant filling compound .The tubes (and fillers ) are stranded around a FRP(Fiber reinforced plastic) as a non-metallic central strength member into a compact circular cable core . After the cable is filled with compound . It is covered with thin PE (polyethylene) inner sheath .After stranded layer of aramid yarns are applied over the inner sheath as strength member . The cable is completed with PE and AT (anti-tracking ) outer sheath.
Features
1.Can be installed without shutting off the power
2.Excellent AT performance, the maximum inductive at the operating point of AT sheath can reach 25 KV
3.Light weight and small diameter reducing the load caused by ice and wind and the load on towers and backprops
4.Large span length
5.Accurate control on Aramid application greatly improving the strength of cables
6.Accurate fiber excess length and stranding pitch to ensure the good performance of tensile strength and the temperature
二、OPGW fiber 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.
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)
