Copper Conductor XLPE Insulated PVC Sheathed Power Cable

Copper Conductor XLPE Insulated PVC Sheathed Power Cable


Product Introduction

This product of silane XLPE insulated PVC sheathed power cable applies to electric line at rated voltage 0.6/1Kv, the mechanical properties and electric proprties of the cable comply with the standard of GB/T12706.1-2008 and IEC60502-1997. Flame resistant cable should be accorded with GB/T19666-2005.

single core xlpe power cable

The conductor material is copper, the insulating material is XLPE, and the sheath is PVC. We could produce the power cable with flame retardant or fire-resistant cable, or according to customers' requirements.

XLPE POWER CABLE

Operating Characteristics

1. The highst rated working temperature of conductor is 90°c; the highest temperature is no higher than 250°c in short circuit (the longest duration is 5 secs).

2. Bending Radius

    The minimum bending radius of non armoured cable: multiple-core cable is 12D.

    D is the diametr of the finished cable.

3. The environment temperature for laying cannot be lower than 0°c, below 0°c installation must be preheated.

Main Application

 

Type Designation Main Application
YJV Copper Conductor XLPE Insulated PVC Sheathed Power Cable For laying in tunnels and ducts of indoor and outdoor, able to bear a centain traction installation, but unable to bear pulling force and pressure, single core cable can not be laid in the magnetic tube. Flame retardant, fire-resistant cable are suitable for the places withhigher requirements for fore protection.
