1.Standard: 

   Company Standard

2.Application

  For High-power electricity transmission, electromagnetic, laser accelerator DC high voltage system and electrical control device transmission and          connection cables, with good characteristics of high load, solar ageing resistance. It has the ability of resisting working pulse current and short circuit    fault current, and can meet the data index of inductance and capacitance.

3. Operating Performances:

   1). Conductor DC resistance at 20℃ meets standard of circle copper conductor as per GB/T 3956 class5.

   2).The long-term allowed continuous operating temperature is 90℃;

   the outdoor ambient temperature is -20~+70℃；

   the minimum allowed bending radius is 10D(D: diameter of cable).

   3).Finished cables can bear 50Hz DC;
