China 22kv Medium Voltage Underground XLPE Power Cables

22kV Medium Voltage Underground XLPE Power Cables
Application:
Media Voltage XLPE Insulated 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.
Prpperty:
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.They can stand advisable traction when laid.They can stand traction from Outside.Left low smoke halogen-free after burned.Retard the burning of the cable.
Specification:
Standard:
IEC60502,designing and manufacturing special power cable according to the other standards required by the customers.
