fire alarem power cable

 

 

Product standard

The electric property of the product is the same as those common wire and cable, and its properties of fire-resisting conform to the GB/T18380-2001(IEC60332:1993) and GB/T19216.21-2003 the State Standard or the GA306-2007 the Public Safety Industrial Standard regulated by the State.

Usage

This product is suitable for use in all places using rated AC voltage 1-10kV plastic insulated power cable, 450/750V plastic insulated control cable, 450/750V and below electrical equipment wire and cable, particularly high temperature, inflammable and fire-proof for transmitting and distributing power, control, alarm fire-control system and other circuits.

Property for Use

1. According to different product kinds, rated voltage can be divided into the following:

   a,0.6/1-8.7/10kV b,450/750V c,300/500V  d,300/300V

2. Allowed work temperature of cable for a long period is divided into the following according to different kinds of products: 70°C, 90°C, 105°C.

 3. For short circuit (5s), the allowed max. work temperature of conductor does not exceed 160°C and 250°C (for 1-a).

4. Environmental temperature for laying cable should not be less than 0°C.

5. Allowed min. bend radius of cable should be according to different kinds of the following products: 6 times, 10 times, 12 times and 15 times of cable overall diameter.

6. Cable combustion nature

   a. Under flame temperature 750-800°C combustion conditions, cable can normally operate not less than 90 min.

   b. Measured cable current-carrying capacity under “a” environment is not less than the current-carrying capacity

     value under work conditions of less than the current-carrying capacity value under work conditions of corresponding type and specifications of common cable.

7. Other electric nature and physical-mechanic nature of cable are all higher than corresponding cable.
