Embodiment Construction

[0021] Such as figure 1 The schematic diagram of the shown elastomer polyvinyl chloride nylon sheathed cable of the present invention comprises a plurality of wire cores, filling rope 3, inner sheath 4 and outer sheath 5, and described wire core is wrapped in its outside by conductor 1 Insulation layer 2 is composed of multiple wire cores and filling ropes 3 which are stranded at equal intervals to form a cable core. The core is extruded with an inner sheath 4, and the outer sheath 4 is The extruded package has an outer sheath 5 . The conductor 1 is copper or aluminum, and the insulating layer 2 is low-smoke halogen-free polyolefin. The filling rope 3 is polypropylene filament. The inner sheath 4 is made of polyvinyl chloride elastomer. The outer sheath 5 is made of nylon 12 as material.

Abstract

The invention discloses an elastic body polrvinyl chloride nylon sheathed cable. The elastic body polrvinyl chloride nylon sheathed cable comprises a plurality of cable cores and sheathes, wherein the cable cores consists of conductors and insulated layers packaged at the exteriors of the conductors, and the cable cores and filling ropes are twisted to form the cable cores; and inner sheathes are pressed and packaged outside the cable cores, and outer sheathes are pressed and packaged outside the inner sheathes. According to the cable, the structure is simple, proper materials are selected, the environmental pollution is avoided, the friction coefficient of the cable is small, the tube penetration is convenient, the chemical resistance is good, and the cable has the functions of defending mice and ants; and better mechanical property can be still maintained under a rugged environment, and the service life can be up to 40 years.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to an elastomer polyvinyl chloride nylon sheathed cable. Background technique [0002] The cables used in construction and some special occasions require the cables to be wear-resistant, soft, anti-mouse and termite-proof, and easy to wear through pipes, etc., but ordinary cables cannot meet the above requirements. Contents of the invention [0003] The object of the present invention is to provide an elastomer polyvinyl chloride nylon sheathed cable. The cable has the advantages of simple structure, proper material selection, no pollution to the environment, small cable friction coefficient, convenient pipe penetration, good chemical resistance, and the function of preventing rodents and termites. It can still maintain good mechanical properties in harsh environments and has a long service life. Up to 40 years. [0004] The purpose of the present invention can be ach...
