At present, safety sliding contact wire (tubular, closed), single-pole combination sliding contact wire, rigid body sliding contact wire, multi-stage tubular safety sliding contact wire, jointless safety sliding contact wire, cable safety sliding contact wire, I-steel cable pulley, etc. are widely used, with great improvement in protection grade and insulation, safe and reliable.

It can be said that there are many types of safety sliding contact lines, which emerge in endlessly. However, products need to be innovated, and all need to introduce the old and bring forth the new. Therefore, natural changes must be indispensable at this time. Here, I want to say that we have to fully understand the root of all these innovations, and we must fully understand him to stand at the top of the safety slide line. So let's discuss with you how to improve the safety sliding contact line.
