ADSS Double Layer All-Dielectric Cable For 100-400M Span
Characteristics of ADSS:
Light weight, small cable diameter, reducing the ice;
Can be continuously electric erection;
Using AT sheath, large span
Description:
ADSS Double Layer Cable is used for communication cable of overhead high-voltage electricity transmission system,also can be used at the areas where lighting is frequent or distance is big. Aramid yarn is used as the strength member to assure the tensile and strain Performance.Mainly installed at existing 220kV or lower voltage power lines . Two Jacket and stranded loose tube design
According to different Related Strength Tension which suitable different situation. Please check the Cable Performance Parameter according to the 10-30 KN.
