Http://www.ahdqjt.com     Time: 11/07/10 09:46

   It is used as power transmission cable of electric equipments of rated voltage 0.6/1kV or lower in bad environment or that high temperature. It has good features of high temperature resistance, flame resistance, radiation resistance, aging resistance, ozone resistance, water proof, freezing resistance, weather resistance, etc.

Executive standard: enterprise standard

Performance for Usage

  1. rated voltage U0/U: 600/1000V
  2. Working temperature allowed by cable is -60℃~180℃
  3. Max. temperature of cable conductor is no more than 250℃ during short circuit(The longest lasting time is no more than 5s)
  4. Temperature for installing is no less than -20℃
  5. Bending radius of cable as follows:

It is no less than 15 times that of cable outer diameter for cable with single core
It is no less than 12 tomes that of cable outer diameter for cable with three cores
