NA2XRY/YJLV32 MV Aluminum Power Cable

Release time:2021-05-15

Aluminum Core XLPE Insulated Fine Steel Wire Armored PVC Sheathed Power Cable


Product description:
This product is suitable for power transmission and distribution lines with rated power frequency voltage 3.6/6kv~26/35kv for electrical energy distribution.
The cross-linked polyethylene insulated power cable adopts chemical or physical methods to transform the polyethylene molecule from a linear molecular structure to a three-dimensional network structure, and from a thermoplastic polyethylene to a thermosetting cross-linked polyethylene, thereby improving the polyethylene The anti-aging performance, mechanical performance and environmental resistance ability, and maintain excellent electrical performance.
The allowable long-term maximum temperature of the conductor of cross-linked polyethylene insulated power cable is 90 degrees Celsius, lower insulated cables, PVC insulated cables and polyethylene insulated cables are high, and have light weight, simple structure, convenient use, chemical resistance and laying It is not subject to the limitation of the drop.

Operating characteristics:
· Rated power-frepuency voltage U0/U: 3.6/6kv~26/35kv.
· Max.admissible operating temperature of the conductor:90℃.
· Max. short-circurt temperature of conductor shall not exceed 250℃.
(5s maximum duration)
· The ambient temperature under installation should not below 0℃.
· The bending radius of a single-core cable should not less than 20 times of the cable diameter.
· The bending radius of a single-core cable should not less than 15 times of the cable diameter.
