PE Fiber & Mica Compound Insulated Fire-proof Mine Signal(soft) Cable, Fire Proof Cable
Specifications
The electric property of the product is the same as those common wire and cable, and its properties of fire-resisting conform toflame retardant fire resistant cable
- 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 otter circuits.
- Property for Use
1.According to different product kinds, 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(for1-a).
4.Environmental temperature for laying cable should be not 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 common cable.
- Scope of Application
Mine pit signal transmission & monitoring fire-proof places
