0.6/1kV Al/XLPE/STA/PVC Insulated Power Cable

Introduction

XLPE insulated power cables for rated voltages of 1 kV (Um = 1,2 kV) is used to transmit power on the power transmission and distribution line of A.C.50Hz, rated voltage 1kV or below. They are well adapted to underground use in industrial applications with an additional mechanical protection. These cables can be fixed on cable trays, within conduits or fixed to walls.

Executive standard:

IEC60502-1 Power cables with extruded insulation and their accessories for rated voltages
from 1 kV (Um = 1,2 kV) up to 30 kV (Um = 36 kV)
Part 1: Cables for rated voltages of 1 kV (Um = 1,2 kV) and 3 kV (Um = 3,6 kV)

Instruction of Application

--Rated Voltage: 0.6/1kV
