NH-YJV,NH-YJV22 Cross linked polyethylene insulated fire-resistant power cableDetailed product description：

Execution standard: Q/VAHS 7-2006

Purpose:
NH-YJV, NH-YJV22 cross-linked polyethylene insulated fire-resistant power cable is suitable for high-rise buildings, subways, power stations, industrial and mining enterprises and other important places related to fire safety and firefighting with an AC rated voltage of 0.6/1kv and below, such as power supply lines for emergency equipment such as firefighting equipment, fire alarm devices, communication smoke exhaust equipment, and emergency guide lights.

Usage characteristics:
(1) Usage temperature: The maximum operating temperature of the cable conductor is 90 ℃, and the ambient temperature during installation should not be lower than 0 ℃.
(2) Allowable bending radius: For unarmored cables, it shall not be less than 15 times the cable diameter, and for armored cables, it shall not be less than 12 times the cable outer diameter.
