4X95+50mm2 Copper XLPE Insulated PVC Sheath Electrical Power Cable
Product Description
CONSTRUCTION: CU/XLPE/PVC or PE
Operation characteristic
The maximum operating temperature of cores shall not exceed 90ºC ween the cable used for a long period. The temperature of cores shall not exceed 250ºC at short circuit for 5 seconds. The ambient temperature should not be below 0ºC during installation.
The permissible bending radius for cable should be the permissible bending radius for cable shall be complied with the regulation as below:
For single-core No armoured cable: R>20(D+d)±5% For multi-core:R>15(D+d)±5%
Armoured cable:R>15(D+d)±5% For multi-core:R>12(D+d)±5%
Where:R-being radius(mm) D–overall diameter of the cable(mm)
d-diameter of conductor(mm)
The single core cable of using in AC circuit shall be without armour or with steel wire armour and shall not be laid in magnetic ducts.

Installation and operation condition of cable
In air:
1. The single-core cables are parallel laid,the distance between the cable center is 2 times of the cable diameter for cross-section area of conductor≤185mm² and 90mm for cross sectional area of conductor ≥240mm²
2. Ambient air temperature:40ºC
3. Max.Continuous operating temperature of conductor:70ºC
