0.6/1kV Cu/XLPE/SWA/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.

  • High strength
  • Large current carrying capacity
  • Good catenary property and wear-resistance
  • Anti-crush and corrosion-proof with simple structure
