Product Description

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

Application: 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.
 

ENGINEERING  SPECIFICATIONS

Standard  EN 50397-1
Rated Voltage  12/20 or 18/30 kv
Conductor  stranded aluminum alloy wire(AAAC) or ACSR.
Core  the conductor is  insulated with a layer of extruded XLPE .
Sheath  over the insulated core is applied an outer protecting  layer of extruded HDPE compound.
 Operating temperature  90°c continues normal operation.
