Each group of wires is insulated from each other and often twisted around a center. The whole is covered with a highly insulating covering layer. The cable has the characteristics of conducting electricity inside and being insulated outside.

There are several groups of conductors, and all several groups of conductors are installed inside the braided layer; the conductor has a cylindrical structure, an insulating layer is arranged outside the conductor, the insulating layer is made of rubber material, and an inner sheath is arranged outside the insulating layer; the braided layer is made of tinned copper wire material, and a non-woven fabric layer is arranged inside the braided layer; a filling layer is arranged between the non-woven fabric layer and the conductor, and protective cotton yarn is filled in the filling layer; the sheath layer is made of plastic material, and anti-slip lines are arranged on the surface of the sheath layer, and the anti-slip lines are of a concave-convex structure.
