                              No Halogen Flame Retardant and Fire Resistant Power Cable

 

 

Application

 

This product is suitable for AC 0.6/1kV of power frequency or below equipment, fire hazard and fire fighting equipment, emergency passage transportation, lighting, etc emergency facilities where the power supply requires fireproof fields. Particularly it is suitable for subway, under-ground shop, high-rise, intelligence communication building, power station and so on fields with high safe requirements.

 

Product characteristics

 

1. With all characteristics of no halogen low smoke fire retardant power cable.
2. Burn at 800°C and below flame environment, can guarantee to electrify over 180 min. compared with ordinary cable, its time of fireproof can prolong two times, the safety is better.

 

Type and Specifications

Type	No. of Core	Nom. area Cross-Section area mm2
WDZN-YJY WDZN-YJY23 WDZN-YJY33	1	2.5~1000
	2,3,4,5	4~240
Note: When 1-core cable needs to armor, the cross section should not be less than 10mm2. Meanwhile it should use non-magnetic material or reduce magnetic loss structure.
