1.20.6/1kV Cu or Al/XLPE/STA/PVC Insulated Power Cables

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 specifically suitable for use in industrial applications, particularly underground installations, where additional mechanical protection is required. These cables can be securely installed on cable trays, within conduits, or fixed to walls.

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 specifically suitable for use in industrial applications, particularly underground installations, where additional mechanical protection is required. These cables can be securely installed on cable trays, within conduits, or fixed to walls.
Instruction of Application
Rated Voltage: 0.6/1kV
Conductor
Class 1 solid copper/aluminum conductor
Class 2 stranded circular or circular compacted

Insulation
XLPE (Cross-Linked Polyethylene)
