Medium Voltage Cable XLPE Insulated Armored Power Cable
Type: Armored Cables Insulation thickness: 1.0-10.5mm Armored: (74-106)*3.15 Jacket thickness: 1.0-5.0 Calculated diameter: 11.4-125.6mm
1, Application
Medium Voltage Cable XLPE Insulated armored 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.
2, Characteristics
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.
