Application
PVC/XLPE power cable 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.
Standards
The power cable is mainly complying with IEC60502,GB/T 12706 standards.It also can be produced according to OEM requirements and other standards, such as BS, DIN, ASTM, VDE, NFC standards, and so on.
Production range
Single core cable: from 1.5 mm2 to 800 mm2 ,
Multi-cores cable: from 1.5 mm2 to 400 mm2 .
Properties of PVC Power Cable
1.The long-time permissible working temperature of cable conductive core is not more than 70 degrees.
2.During short circuit (max permanent time is not more than 5 seconds), the max temperature of cable conductor is not more than 165°C.3.The difference level of laying cable is not restricted.When laying the cable,ambient temperature is not lower than 0°C.4.They have good chemical stability,and properties of acid resistance,alkali resistance,salt resistance,oil resistance,solvent resistance and flame resistance.
Properties of XLPE Power Cable
1.The highest allowed operating temperature of conductor for long-term working is 90 degrees.
2.In short circuit (Max long term is no more than 5 seconds). The highest temperature for conductor is no more than 250 degrees.
3.The cable is laid without horizontal drop limit. The environment temperature should be no lower than 0 when lay. Otherwise it should be preheated.
4.Excellent electrical performance, resistance to chemical corrosion.
5.Can stand advisable traction when laid.Can stand traction from Outside.Left low smoke halogen-free after burned.Retard the burning of the cable.
Operating characteristics
1. long time operating temperature for cable conductor is 90 degrees.
2. the highest temperature of the conductor in short circuit (no longer than 5 seconds) in not more than 250 degrees,
if a joint is in the cable, the temperature of the tinning welding joint is not more than 120 degrees, compressing joint not more than 150 degrees and electro- welding joint not more than 250 degrees.
3. no drop in limited provided there is full mechanical tention when cable is laid. It si forbidden to lay cable in iron-pipe or to fix cable by circling around the cable with iron materials.
4. being laid, the minimum temperature of the cable shall not be lower than zero degree. In the case of lower temperature, heating measures shall be taken.
