Http://www.ahdqjt.com     Time: 11/10/10 10:33

   It is used for supervising and controlling return circuit of A.C. rated voltage of 450/750V or lower, power connection of various mobile electrical equipments, radio devices, and lighting & protection under low temperature.

Executive standard: enterprise standard and JB1170-75 standard

Working condition

  1. Long-term working temperature of wire conductor is no more than 180℃ for cable with silicon insulation, 70℃ for that with PVC insulation
  2. Min. environment temperature of wire is -40℃
  3. Bending radius allowed by wire is no less than 8 times that of cable O.D OR 6 times for cable with soft structure.
