Flexible fine copper wire shielding drag chain power cable

Abstract

Provided is a flexible fine copper wire shielding drag chain power cable. The cable is formed by a conductor layer, a first separating layer, an insulating layer, a second separating layer, a shielding layer, a third separating layer, and an outer sheath layer in sequence from the inside to the outside, the conductor layer is a conductor layer formed by the twisting of type-6 ultra-soft structure conductors in IEC60228, the first separating layer is a layer of polyester tape wrapping the outside of the conductor layer in an overlapping manner, the insulating layer is an ethylene propylene rubber insulating layer, the second separating layer refers to two layers of polyester tapes wrapping the outside of the insulating layer in an overlapping manner, the shielding layer is a copper wire braided shielding layer, the third separating layer refers to two layers of polyester tapes wrapping the outside of the shielding layer in an overlapping manner, and the outer sheath layer is a neoprene outer sheath. According to the flexible fine copper wire shielding drag chain power cable, problems of short usage time and easy occurrence of faults of the conventional drag chain cables can be solved, and the mechanical property, flexibility, frequent bending resistance, and wear resistance are excellent.

Description

technical field [0001] The invention relates to a towline power cable, in particular to a flexible and fine copper wire shielded towline power cable with excellent mechanical properties, flexibility, frequent bending resistance and abrasion resistance. Background technique [0002] Drag chain cables are mainly used in: industrial electronic systems, automatic production lines, storage equipment, robots, fire protection systems, cranes, CNC machine tools and metallurgical industries. Various damages and failures occur in the cables in about half a year, and the scrapping period is very short, and the use cost is relatively low. High, generally use imported cables, imported cables have good performance, but the price is expensive. [0003] The internal cable core structure of traditional PVC insulated cables is unstable, the conductor monofilament is relatively thick, the twisting pitch is large, and the shielding is not dense, so that the deformation of the twisted core will ...
