600volt Cable XLPE Insulated Copper Screened PE Sheathed 4core

Relative manufacturing standards: IEC60505, BS, DIN,ASTM,JIS or other standards.
 
Application: 
It is used to transmit and distribute power in power transmission and distribution system of 35kV or lower. It is generally applied to the fields including power, construction, mines, metallurgy, petrochemical industry and communication in complete replace of oil immersed paper insulated power cable and in partial replace of PVC insulated power cable.

DESCRIPTION Circular compacted and shaped stranded aluminium conductor, XLPE insulated, four cores assembled together with nonhygroscopic filler, extruded with PE inner sheath, copper tape screened and followed by an extruded PE outer sheath. Cables are rated at 0.6/1 (1.2) kV and conformed to IEC 60502.

CONSTRUCTION
1. Conductor Plain compacted or shaped stranded aluminium conductor, conform to IEC 60228 class 2.
2. Insulation XLPE (cross-linked polyethylene) rated at 90 o C.
3. Colours for core identification Four cores – red, yellow, blue, and black
4. Assembly Four insulated conductors are laid up together, if necessary filled with non-hygroscopic material compatible with the insulation and inner sheath materials.
5. Inner Sheath Medium density polyetylene (MDPE).
6. Metallic Screen Copper tape screen (SCT).
7. Sheath Medium density polyethylene (MDPE).

XLPE INSULATED SCREENED PE SHEATHED CABLE – FOUR CORES AL/XLPE/MDPE/SCT/MDPE CABLE ( WITH COPPER TAPE SCREENED ) 0.6 / 1 (1.2) kV
 

Using features: 
1. Rated voltage: Uo/U: 26/35kV, 21/35kV, 12/20 kV (24 kV), 8.7/10kV, 8.7/15kV, 6/6kV, 6/10kV and 0.6/1kV.
2. No. Of core: Single-core, Two-core,Three-core,Four-core,Five-core,Six-core.
3. The highest allowed operating temperature of conductor for long-term working is 90oC. In short-circuit (Max. Long-term is no more than 5 seconds). The highest temperature for conductor is no more than 250oC. 
4. D. C. Resistance of the conductor complies with the stipulations of international standar. 
5. The environment temperature should be no lower than zero degree when lay. Otherwise it should be preheated. 
6. The cable is laid without horizontal drop limit. The Min. Bending radius of cables should be no smaller than 12 times of cable outer diameter. 
7. Working Frequency Voltage Test: 
For cable with Uo of 3.6kV or lower: 2.5Uo+2kV/5min without puncture. 
For cable with Uo of 3.6Kv~18kV: 3.5Uo/5min without puncture. 
For cable with Uo of 21kV and 26 kV: 2.5Uo/30min without puncture. 
8. Partial Discharge Test: The discharge volume should be no more than 10pC under 1.73Uo for the cable
