XLPE Insulated Cold-Resistant Power Cable

The XLPE insulated cold-resistant power cable is suitable for power transmission and distribution lines that work under low temperature, and the rated voltage is 35kV or lower. Our product can maintain its excellent mechanical and electrical properties even at -40℃, so stable performance is offered.

Features
1. For long-term application, the maximum working temperature of conductor is 90℃, and the minimum value is -40℃.
2. During short circuit which lasts for no more than 5 seconds, the maximum temperature of conductor is not over 250℃.
3. Our product features superb cold-resistant performance, and there are no visible cracks even if the cold-resistant sheath is tested at -40℃ for 16 hours, and the test is in accordance with the GB/T 2951 standard.
4. When installing our product, the ambient temperature should not be lower than -10℃, and there is also requirement for bending radius. The bending radius should be no less than 15 times and 20 times of cable diameter for single core type and multi-core type, respectively.
5. This cold-resistant power cable has similar size and weight when compared with common XLPE insulated power cable with the same specification.
