Product Description

 

12/20 18/30 kv Medium Voltage Overhead Covers Conductors Thick (CCT) - Cables
Medium Voltage Overhead Covers Conductors Thick Application

Medium Voltage Overhead Covers Conductors Thick (CCT) - Cables used in power supply in power transmission and distribution line.

Overhead single core cables with aluminum alloy conductor and XLPE insulation, for overhead power transmission and distribution lines up to 20 K & 33 KV. The Covered Conductor Thick (CCT) system, although not a touch-safe screened cable system, is designed to provide protection from initiation of flash-overs due to clashing of conductors, bird or animal incursions, and tree branches or debris which has blown or fallen on to the line , specially in Weather conditions pollution.
