Problems solved by technology

[0002] At present, the optical cable and the phase conductor of the power transmission line, the overhead ground wire and the power cable are combined into one structure, that is, the optical cable. This structure has dual functions of ground wire and communication. Electric special optical cables are laid along high-voltage power lines, but ordinary cables cannot effectively resist interference, and have low tensile strength and weak anti-static performance. The main reason is that the structure and material design and selection of cables are unreasonable.

Embodiment Construction

[0009] Such as figure 1 As shown, an anti-static and anti-stretching cable is composed of a polyperfluoroethylene propylene outer sheath 1, a tinned copper wire braided shielding layer 2 and a cable core, and the cable core is extruded by a fluorine rubber insulating layer 3 It is formed by wrapping three power wire cores; the power wire core is formed by extruding ceramic powder polyvinyl chloride inner shielding layer 4 and wrapping three insulated wire cores; the insulated wire core is provided with a drain wire core 5; the three power wire cores A tensile steel wire rope 8 is arranged in the middle of the core; the outside of the cable core is coated with a tinned copper wire braided shielding layer 2 and a polyperfluoroethylene propylene outer sheath 1 in sequence.

[0010] The insulated wire core is formed by wrapping an aluminum alloy conductor 6 with a polyvinyl chloride insulating layer 7 .

[0011] Compared with the prior art, the beneficial effect of the present in...

Abstract

The invention discloses an anti-static stretch-resistant cable which is composed of a FEP outer sheath, a tinned copper wire braided shielding layer and a cable core. The cable core is formed in the mode that a fluoride rubber insulating layer wraps three power cores in an extruding mode, and the power cores are formed in the mode that a ceramic powder PVC inner shielding layer extrudes three insulation cores; drainage cores are arranged in the insulation cores, a tensile steel wire rope is arranged in the three power cores, and the cable core is wrapped by the tinned copper wire braided shielding layer and the FEP outer sheath in sequence. The anti-static stretch-resistant cable is suitable for laying high voltage wires and power lines, and good in electric performance and interference resistance, and has the advantages of being anti-static, and high in structure strength.

Description

technical field [0001] The invention relates to the field of cables, in particular to an antistatic and anti-stretching cable. Background technique [0002] At present, the optical cable and the phase conductor of the power transmission line, the overhead ground wire and the power cable are combined into one structure, that is, the optical cable. This structure has dual functions of ground wire and communication. Electric special optical cables are laid along high-voltage power lines, but ordinary cables cannot effectively resist interference, and have low tensile strength and weak anti-static performance. The main reason is that the structure and material design and selection of cables are unreasonable. Therefore, it is necessary to provide a new technical solution to solve the above problems. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide an antistatic and anti-stret...
