Abstract
The invention relates to a cable for signal transmission. The cable comprises a pair of insulated cable cores which are twisted to be a pair. A polyester film layer is used for covering the insulated cable cores and net ropes are used for filling the insulated cable cores. An overall braided shield layer covers the polyester film layer, and an insulated protective sleeve layer is further arranged outside the overall braided shield layer. Soft twisted copper wires and soft polyether type TPU resin are adopted by the cable so that the control cable can be suitable for mobile places. The polyester insulated layer facilitates achieving of extremely low medium losses, and the effect of high electromagnetic-interference-resistant performance is achieved with the braided shield layer. In addition, the polyether type TPU resin not only has good flexibility and winding-resisting performance, but also is resistant to acid, alkali and hydrolysis and good in stability.
