Anti-static, anti-corrosion, waterproof and stretching-resistant insulated cable

Abstract

The invention discloses an anti-static, anti-corrosion, waterproof and stretching-resistant insulated cable. The anti-static, anti-corrosion, waterproof and stretching-resistant insulated cable comprises a cable body. The cable body comprises cable cores, a cable core protective layer, an insulating layer, a shielding layer and an outer jacket. The cross section of the cable core protective layer is of a circular structure, and the multiple evenly-arranged cable cores are arranged in the cable core protective layer and separated through PVC plastic connecting rods; a plurality of current guide cores are arranged outside the cable core protective layer and are tangent with the cable core protective layer; the insulating layer is arranged outside the cable core protective layer; waterproof fillers are arranged in a gap between the insulating layer and the cable core protective layer; the shielding layer is tightly extruded on the insulating layer and internally provided with the multiple evenly-arranged current guide cores; a breakdown resistant layer, a steel core protective layer and a waterproof layer are sequentially extruded on the shielding layer from inside to outside; an armor layer is extruded outside the waterproof layer, the outer jacket is arranged outside the armor layer, and a graphite layer is arranged between the armor layer and the outer jacket. The anti-static, anti-corrosion, waterproof and stretching-resistant insulated cable has the advantages of being reasonable in structural design, high in anti-static capacity, good in anti-corrosion performance and the like.

Description

technical field [0001] The invention relates to the field of cables, in particular to an antistatic, corrosion-resistant, water-resistant, stretch-resistant insulated cable. Background technique [0002] At present, with the development of science and technology, all walks of life are developing in the direction of industrialization and electronics, which also means that the amount of cables is greatly increased, but because the working environments of various industries are different, it is also required that cables The characteristics are different. As far as the current development of science and technology is concerned, people require that the cable not only has the single function of transmitting current, but also the cable can be anti-static and corrosion-resistant to a certain extent. It is well known that internal static electricity often occurs when cables are used. Or the situation of being broken down by high voltage seriously affects the normal use of equipment a...

[0002] At present, with the development of science and technology, all walks of life are developing in the direction of industrialization and electronics, which also means that the amount of cables is greatly increased, but because the working environments of various industries are different, it is also required that cables The characteristics are different. As far as the current development of science and technology is concerned, people require that the cable not only has the single function of transmitting current, but also the cable can be anti-static and corrosion-resistant to a certain extent. It is well known that internal static electricity often occurs when cables are used. Or the situation of being broken down by high voltage seriously affects the normal use of equipment and brings a lot of inconvenience to people. The Chinese patent document application number is a kind of waterproof and antistatic insulated cable of CN201420134708.1. It is composed of wire core, resistance It is composed of water-wound cladding and ceramic fluororubber outer sheath. It uses water-blocking wrapping to achieve waterproof effect, and uses ceramic fluororubber outer sheath installed outside the cable to shield static electricity. However, this structural design is relatively Simple, only relying on a single material cannot effectively shield static electricity, and this structure cannot be used in harsh environments, does not have strong tensile properties, and often brings great problems in the later stage
