The GYFTY-PKP Double Sheath Loose tube Outdoor Optical Fiber Cable is loose tube stranded Fiber cable, which is 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 and circular cable core. After the cable core is filled with filling compound. it is covered with thin PE (polyethylene) or LSZH inner sheath. After stranded layer of aramid yarns are applied over the inner sheath as strength member, the cable is completed with PE or LSZH outer sheath.
Features
Can be installed without shutting off the power
Light weight and small diameter reducing the load caused by ice and wind and the load on towers and backdrops
Good performance of tensile strength and temperature
Applications
ADSS optical fiber cable plays a significant role in the communication industry. Its usage is gradually increasing with more people choosing it in expense of other fiber cable. Some of its outstanding features have enhanced its demand throughout the market.This article analyses the key applications of the ADSS optical fiber cable. The research showed that, ADSS optical fiber cable’s demand is high particularly in areas of transmitting high-voltage power.
