Long-term allowable working temperature of the core should not exceed 70 degrees, the cable environment temperature of -40 degrees to 60 degrees. Integrated sheathed, aluminum sheaths are shielded, are applicable to the computer through the need to set the shielded cable electrification section. Cable conductor for the copper conductor, conductor diameter 1.0mm, core insulation using high-pressure polyethylene, insulation thickness 0.6mm thickness tolerance of 0.1mm. Insulated wire stranded when the adjacent two layers of twisted in the opposite direction, the number of cores for more than 7 core cable, each layer should be red and green core number as a mark line. And is different from the color of other cores in the same layer
