Abstract

The invention discloses a controlling cable which comprises a plurality of wires. The wires are twisted to form two sets, the outside of each set of wires is covered with an insulating layer, and the outsides of the insulating layers of the two sets of wires are together covered with a low smoke zero halogen flame retardant belt wrapping layer. An H-shaped nylon skeleton is arranged in the low smoke zero halogen flame retardant belt wrapping layer, and the H-shaped nylon skeleton is wrapped with the two sets of wires. The outside of the low smoke zero halogen flame retardant belt wrapping layer is sequentially coated with a semiconductive shielding layer, a polyester silk knitting tear-resistant layer and a jacket layer. The gap between the polyester silk knitting tear-resistant layer and the PVC jacket layer is filled with a mixture of water stopping paste and water stopping powder. According to the controlling cable, the inner structure layer is simple, various properties such as insulation, water resistance and compression resistance of the entire cable cannot be affected, mounting is convenient, and the practicability can be achieved.

Description

technical field [0001] The invention relates to cables, mainly a control cable. Background technique [0002] Control cables are mainly used for transmission control, suitable for energy and transportation departments, and for occasions such as controlling and protecting lines with AC rated voltage below 450 / 750 volts. The cable standards are strict, and the structure of the general control cable is complex to ensure the integrity of the cable as a whole. Various properties, the existing cable sheathing material has disadvantages such as poor aging resistance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a control cable, which has a simple internal structure, but does not affect the overall performance of the cable, such as insulation, water resistance, and compression resistance, and is easy to install and has good practical performance. The cable sheathing material of the invention has good aging resistance...
