MEDIUM VOLTAGE CABLE APPLICATION

The cable is used for fixed installations such as electric power distribution networks or industrial installations, which is laid indoors, outdoors, in tunnel, in cable trench, or direct in ground, able to bear external mechanical force, but unable to bear large pulling force.

Fire Resistant 21KV XLPE Insulated Power Cable , DSTA XLPE Armored Cable 1

MEDIUM VOLTAGE CABLE CHARACTERISTICS

1. Max Long-time operating temperature of XLPE insulated cable is 90°C

2. Installing temperature of cable should not be less than 0°C

3. Max short-circuit temperature is not exceed 250°C,Not more than5 Sec.

4. Unable be laid without the limit of fall with enough mechanical pull,Single core cable can not be laid in iron tube or fixed by circled iron tools around cables
