3X70mm Power Cable XLPE/PVC Insulation Copper Rated Voltage Mv Construction Electric Cable

Introduction

This cable is used to transmit power on the power transmission and distribution line of A.C.50Hz, rated voltage 36kV or lower. They are suitable for installations indoors: mostly in power supply stations and outdoors: in cable ducts, underground, and on cable trays for industries, switch-boards and power stations.

Executive standard

IEC60502-2 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 2: Cables for rated voltages from 6 kV (Um = 7,2 kV) up to 30 kV (Um = 36 kV)

Instruction of application

Rated Voltage:

3.6/6 (7.2) kV

6.0/10(12) kV

8.7/15(17.5) kV

12/20(24) kV

18/30(36) kV

The ambient temperature for cable installation :≥0 ⁰C

This minimum working temperature of the cable is -20 ⁰C

This maximum working temperature of the conductor is 90 ⁰C;

During having a short (lasting less than 5 seconds) the maximum temperature of the cable conductor shall not be above 250 ⁰C;

Bending radius allowance of the cable:

Cable Construction Description

Conductor
Class 2 stranded circular or circular compacted
Semi-Conductive Layer for Conductor
Semi-conductive material
Insulation
XLPE (Cross-Linked Polyethylene)
Semi-Conductive Layer for Insulation
Semi-conductive material
Metallic screen
Copper wires / Copper Tape / Copper Wire & Tape
Outer Sheath
PVC (Polyvinyl Chloride)
The conductor Semi-Conductive Layer, XLPE insulation and the insulation Semi-Conductive Layer are extruded simultaneously in one process using triple extrusion method (Continuous Vulcanization Line). Triple extrusion method not only assures clean interfaces between the insulation and stress control layers, but also assures a construction free of Partial Discharge with high operational reliability.
The Main Technical Parameter Of The Cable
1) Cable conductor DC resistance: See the table 1-1
2) Partial discharge test: See the table 1-2
3) AC voltage test: See the table 1-3
4) Rated Voltage,Core Numbers & Nominal Cross-section Area : See the table1-4
Table 1-1 Max. DC resistance of cable conductor at 20⁰C
