Description:
ADSS optical cable has excellent optical transmission properties, mechanical properties and environmental properties. Being one of the most perfect transmission media, it is extensively used in electric power communication networks. In the fields of intense electricity, signals transmitted in ADSS cable are not subjected to any disturbance. Good communication quality will be kept all the time and no injures occur against the cable body. So the transmission with ADSS cable is the most convenient way for telecommunication in the electric power system.
Applications:
ADSS(All Dielectric Self-Supporting)optical cable was mainly applied in electric power system to provide a convenient way to establish communication networks. It is suitable for aerial installation when a communication line has to span a river, a valley, a thunder area and other fields with special requirements. With the opening of telecommunication services, ADSS optical cable not only satisfies the demands of communication of power system but also leave more capability to offer telecommunication service for other industries.
Features:
The primary characteristics of ADSS cable is summarized as follows:
Anti-Electromagnetism, Strong Endurability of Electricity. Elements consisting of ADSS cable are required to be non-metal. The outer jacket material is AT type polyethylene when the space potential intensity at a point along the cable exceeds 12 kV.
Good Temperature and Environment Properties, Suitable for Aerial Operation. In the design of ADSS cable, environmental conditions such as wind, ice, temperature change, creep and so on should be taken into consideration. Then a cable can possess good behaviors such as anti-impact, anti-vibration, anti-bending, prevention of thermal aging, flame retardant et cetera.
Low Cost, Convenient to Installation. It is possible to set up optical cables on the original pylon towers without any change.
Light Weight, Less Load to Tower. The primary tensile strength member in ADSS cable is aramid yarn with high modulus and high strength, which makes the cable lighter in weight when comparing to a cable with steel wires as the primary tensile strength members.
