Problems solved by technology

[0004] At present, the existing cables have poor self-supporting performance, especially when the cable is used in the working condition of not being buried in the ground. Due to the poor bearing performance, the weight of the cable itself will cause the cable conductor to break, and at the same time, it is easy to damage the small cables during construction. conductor
[0005] There are also during the construction process, due to long-term dragging, the outer sheath of the cable is damaged, causing damage to the cable

Abstract

The invention discloses a reinforced solid core conductor polyvinyl chloride insulation sheath-free dragging-resisting cable. The cable comprises a conductor. A steel core is arranged in the conductor. A polyvinyl chloride insulation layer is arranged outside the conductor. A heat tracing belt is arranged outside the polyvinyl chloride insulation layer. A copper filament shielding layer is arranged outside the heat tracing belt. A polyurethane thermal insulation pipe is arranged outside the copper filament shielding layer. The cable is characterized by low-temperature resistance, wear resistance, ultraviolet radiation resistance, bending and winding resistance and dragging resistance.

Description

technical field [0001] The invention relates to the field of cables, in particular to a reinforced solid-core conductor polyvinyl chloride insulated non-sheath drag-resistant cable. Background technique [0002] Cable is an indispensable device in people's production and life. It is usually a rope-like cable twisted by several or several groups of wires. Each group of wires is insulated from each other and often surrounds a cable. The root center is twisted and the entire outside is covered with an insulating covering. The structure is complicated, and the overall installation and laying are troublesome. However, the existing single-core unsheathed cable uses polyvinyl chloride as insulation, which has poor performance and short service life. So people need cables that meet various requirements. [0003] With the footprints of human exploration all over the world, the application of electricity has also extended to every corner of the world, and it is natural to set foot ...
