control cable with xlpe insulation and pvc sheath -尊龙登录

it is used as connection cable of electric appliances and instruments for power distribution devices of rated voltage 600/1000v.

executive standard:

1. temperature for installation & min. bending radius:

preheating is unnecessary when ambient temperature remains no lower than 0℃. installation is free from restriction by drop. and min. bending radius of cable is stipulated as follows:
a: it will be no less than 6 times that of cable od for cable without armor.
b: it will be no less than 12 times that of cable od for cable with armor or that with copper tape shielding.
c: it will be no less than 10 times that of cable od soft cable with shielding structure.

1. long-term working temperature of conductor is 90℃.
2. max. temperature of cable conductor is no more than 250℃ during short circuit within 5s.

main technical parameters:
1. dc resistance of finished cable conductor at 20℃ in table 2

                                                                     table2
2. finished cable should bear a.c. voltage of 3.5kv under power frequency for 5min without puncture of insulation.
3. insulated resistance of cable:
  it is no less than 1.0mω.km at max. rated working temperature.
4. control cable with xlpe insulation has good features of heat resistance, freezing resistance, chemistry resistance, insulated resistance and long lifetime compared with control cable with pvc insulation.
