Product description
Low price 4x4mm2 XLPE insulated PVC sheathed stranded copper power cable
The XLPE insulated PVC or PE sheath high voltage power cable
The power cable as one of our main products, the specification and appliance of the power cable are listing as follows:
1.The standards
The power cable is mainly complying with IEC 60502 standard, also can be produced according to OEM requirements and other standards, such as BS, DIN, ASTM, VDE, NFC standards, and so on.
2.the construction of the power cable for different voltage grade
2.1 low voltage cable power cable
Low voltage (0.6/1 kv)
single core or multi-core
copper or aluminium conductor
pvc inusulation
steel tape armored or galvanized steel wire armored or unarmored
pvc outer sheath
power cable.
2.2 medium voltage cabel power cable
Voltage grade is up to 35kv,
cross-section area can be up to 1000 sqmm (copper or aluminiun conductor).
Conductor long-time operating temperature is 90 degrees.
In short circuit, conductor highest temperature should be not more than 250 degrees.
1kv-35 kv
multi-cores

power cable
2.3 high voltage cable power cable
High voltage (35kv~220kv)
copper or aluminium conductor
xlpe insulation
metal sheath (lead or corrugated aluminium)
hdpe or pvc outer sheath power cable.
Laying conditions: for lyaing under ground with large different altitude, be able to bear external machanical force and moderate pulling force.
3. the power cable's characteristic:
3.1 long time operating temperature for cable conductor is 90 degrees.
3.2 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.
3.3 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.
3.4 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.
4.Brief Introduction
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.
5.Standard
The products can be produced according to our factory specification which is equivalent to the standard IEC60502.The factory can also design and manufacture special power cable according to the other standards required by the customers.
6.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.
