Audited Supplier Medium Voltage Cable Cu or Al/XLPE/CTS/SWA/PVC 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 appropriate for indoor installations: mostly in power supply stations and outdoors: in cable ducts, underground, and on cable trays for industries, switch-boards and power stations.
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
Conductor
copper/aluminum 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
Inner Sheath
PVC (Polyvinyl Chloride)
Amoured
SWA- Steel Tape Amoured
Non-magnetic amoured material used for single core cable.
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
