BS 7889 Low Voltage XLPE Insulated and PVC sheathed MV Power Cable

BS 7889 Low Voltage XLPE Insulated and PVC sheathed MV Power Cable
 
Application :PVC Insulated and Sheathed Power Cable are suitable to be laid for distribution line with A.C.50HZ and rated voltage 0.6/1kV. With the characteristics of stable capability, advanced technology, broad material resources, low price, good flexible and easy to lay and maintain.
1.The long-term permissible operation temperature of the conductor shall not be higher than 70ºC.
2. Conductor maximum short circuit((less than 5 second) temperature shall not be higher than 160ºC.
3. The cable is not limited by drop in level when being laid, and the environment temperature shall not be lower than 0ºC.
4. Perfect chemical stability, resistant against acids, alkalis, grease and organic solvents,and flame retardance.
5. Light weight, perfect bending properties, installed and maintained easily and conveniently.

XLPE insulated power cable are used as electricity power transmission lines which applies common circumstances as below:

• Mainly used for transmitting electricity power or used as control cable.
• Common operating temperature up to 90°C (emergency at 130°C and short circuit 250°C), both wet or dry location.
• Voltage rate 600/1Kv.
• Suits for main or secondary power lines of overhead (aerial) installations, direct burial underground or in dust.
• Cable trunking, cable tray, cable ladder, in tunnel or wire pipe and in switchgear and other complex operating environment.
• Works perfectly after metallic sheath (metal especially aluminum clad) or metal wire armored ( especially steel wire armored - SWA) when isolation of electromagnetic effects, anti-interference, anti-jamming and additional strength are required.
• Product Features:

1. Excellent Electrical and Physical Properties - Much less electricity transmission loss, energy saving.
2. Capability of Carrying Large Currents - Higher operating temperature.
3. Higher strength and stability - Anti thermal deformation, stress crack as well as Thermal Aging.
4. Ease of Installation - No line layout limitation and topography or height restrictions.
5. Free from Maintenance - Long service life up to 60 years.
