Medium Voltage 4 Core XLPE/PVC Armored Power Cable
(8.7/15kV CU/XLPE/SWA/PVC(or PE) Power Cable)
Cables will be produced as per Chinese National Standard GB/T12706.2-12706.3 equivalent to IEC 60502
This product is suitable for using in rated voltage from 6/6kV to 26/35kV system transmission and distribution lines. Based on different sheath structures, it can be used for laying in the air and underground.
3. Installation Place
|XLPE Insulated, PVC Sheathed Power Cable||Laid in indoor, outdoor, tunnels, cable canals, reinforced concrete pipelines and loose soil. Cable should not bear outer mechanic force, but can bear a certain tractional force.|
|XLPE Insulated, Steel Tape Armored and PVC Sheathed Power Cable.||Laid underground. Cable can bear outer mechanic force, but should not bear large tractional force.|
|XLPE Insulated ,fine Steel Wire Armored and PVC Sheathed Power Cable||Laid in indoor, tunnels and mines. Cable can bear outer mechanic force and fairly large tractional force.|
|XLPE Insulated, thick Steel Wire Armored and PVC Sheathed Power Cable.||Laid in vertical section, indoor, tunnels and mines. Cable can bear outer mechanic force and very large tractional force.|
Construction: Compacted stranded circular copper conductor, extruded semi-conducting compound as conductor shield, cross-linked polyethylene (XLPE) insulation, semi-conducting compound as insulation shield, copper tape or combination of copper wire and tape as metallic screen, three cores assembled together with non-hygroscopic polypropylene filler, wrapped with binder tape, PVC inner covering as armoring bedding, galvanized steel wire armored, PVC or PE outer sheath.
2. Operating Characteristics
Rated voltage U0/U(Um): 8.7/15(17.5)kV
U0 is the rated power frequency voltage between conductor and earth or metallic screen for which the cable is designed;
U is the rated power frequency voltage between conductors for which the cable is designed;
Um is the maximum value of the "highest system voltage" for which the equipment may be used.
Max. Permissible continuous operating temperature of conductor: 90 ° C
Max. Temperature of conductor during short-circuit (5s max. Duration) shall not exceed: 250 ° C
The ambient temperature under installation should not be lower than: 0 ° C
The bending radius of cable is recommended as following:
For single core cable: Not less than 15 times of the diameter of cable
For three core cable: Not less than 12 times of the diameter of cable
When the armored single core cable used for Alternative Current(AC) system, the armoring material should be non-magnetic.
The cable is used for fixed installations such as electric power distribution networks or industrial installations, which is laid indoors, outdoors, in tunnel, in cable trench, or direct in ground, able to bear external mechanical force and certain pulling force.
4. Manufacturing Standards
IEC 60502-2 and Chinese National Standard GB/T 12706-2008 We can produce above cables according to popular international standards such as ASTM, BS, DIN, NF &AS/NZ also.
