   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.
