Fire-Proof Wire & Cable Serial Products Suitable For Alarm Fire-control System

■ 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℃, 90℃, 105℃.

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

?4. Environmental temperature for laying cable should not be less than 0℃.

?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℃ 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.
