Xlpe insulated power cable 3.6kv/6kv with copper core
Application
It is suitable for shafts, water and soil, and can withstand greater positive pressure. Media Voltage XLPE insulated power cables are used for power transmission and distribution in 35kV or below power transmission and distribution systems. It is widely used in electric power, construction, mining, metallurgy, petrochemical and communication fields, and completely replaces oil-immersed paper-insulated power cables.
Property
This product is suitable for transmission and distribution lines with AC rated voltage (U0/U) 3.6/6kV-26/36kV, in the air (cable tray, indoor wall rack and pallet) and soil (respectively according to the different direct Buried, cable trenches, pipes, etc.
1. The maximum allowable working temperature of the conductor for long-term work is 90 degrees.
2. In a short-circuit state (the longest duration does not exceed 5 seconds). The maximum temperature of the conductor does not exceed 250 degrees.
3. There is no horizontal drop limit for cable laying. The ambient temperature during laying should not be lower than 0. Otherwise, it should be preheated.
4. Excellent electrical properties, chemical resistance.
5. When laying, keep proper traction force, can bear traction force from the outside, and keep low smoke and halogen free after burning, and the cable is not easy to burn.
