ADSS Uni-tube Or Stranded Structure 2-288 Core Aerial high Tensile Optic Cable with Span
Description
Double Layer Aerial ADSS Cable is used for communication cable of overhead high-voltage electricity transmission system,it also can be used as
communication cable 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 .
Applications
The design of ADSS cable is fully considering the actual situation of the power line and suitable for different levels of high voltage transmission lines. A PE jacket can be used for 10kV and 35kV power lines;but for 110kV and 220kV power lines, the electric field strength distribution must be calculated to determine the cable hanging point and adopt AT outer sheath. At the same time, well-designed Kevlar dosage and thorough stranding process can be met various of application requirements of different spans.
