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.
