Embodiment 1

[0022] Such as figure 1 As shown, a cable with extended service life includes a cross-linked polyethylene sheath layer 6, a carbon fiber conductor 1 is arranged inside the cross-linked polyethylene sheath layer 6, and the carbon fiber conductor 1 is covered with a glass fiber cloth layer 2. The fiber cloth layer 2 is covered with an insulating layer, the insulating layer is covered with an aluminum stranded wire layer 5, the aluminum stranded wire layer 5 is covered with a cross-linked polyethylene sheath layer 6, and the insulating layer includes epoxy resin tetrachlorethylene cross-linked. The joint layer 3 and the rubber layer 4, wherein the epoxy resin tetrachloroethylene crosslinked layer 3 is wrapped outside the glass fiber cloth layer 2, and the rubber layer 4 is wrapped outside the epoxy resin tetrachloroethylene crosslinked layer 3.

[0023] The idea of ​​the present invention is that the existing carbon fiber cables have sufficient strength but insufficient toughness...

Embodiment 2

[0026] Such as figure 2 As shown, the carbon fiber conductor 1 is made of 5-10 carbon fiber composite cores bonded by epoxy resin. If the carbon fiber conductor 1 is formed into a rod alone during use, if it is damaged, the entire cable cannot be used. However, if one of the carbon fiber composite cores is damaged, the other carbon fiber composite core layers can continue to be used. The service life of the cable is extended. At the same time, multiple carbon fiber composite core layers can increase the conductive area and increase the capacitance.

[0027] 5-10 carbon fiber composite cores are arranged in a ring structure.

[0028] The aluminum strand layer 5 is formed by twisting a plurality of aluminum alloy wires, and the cross section of the aluminum alloy wires is lightning-shaped. The cross-sectional shape of the aluminum strand layer 5 may be a lightning bolt shape.

Abstract

The invention discloses a cable with a prolonged service life. The cable comprises a crosslinked polyethylene sheathing layer, wherein the crosslinked polyethylene sheathing layer is internally provided with a carbon fiber conductor; a glass fabric layer is wrapped outside the carbon fiber conductor; an insulating layer is wrapped outside the glass fabric layer; an all aluminum conductor layer is wrapped outside the insulating layer; the crosslinked polyethylene sheathing layer is wrapped outside the all aluminum conductor layer; the insulating layer comprises an epoxy resin tetrachloroethylene crosslinked layer and a rubber layer, wherein the epoxy resin tetrachloroethylene crosslinked layer is wrapped outside the glass fabric layer, and the rubber layer is wrapped outside the epoxy resin tetrachloroethylene crosslinked layer. According to the cable, the carbon fiber conductor can be completely insulated from the all aluminum conductor, so that contact potential difference does not exist between the carbon fiber conductor and the all aluminum conductor; and moreover, sufficient tenacity and support force can be supplied for the cable, so that the problem that the service is short in service life is solved.

Description

technical field [0001] The invention relates to the field of cables, in particular to a cable with extended service life. Background technique [0002] In recent years, the wire and cable industry is in a stage of rapid development. Usually, a cable with only one core and a smaller diameter is called a wire, and a wire without an insulating sheath is called a bare wire, and everything else is called a cable. [0003] At present, wires and cables are used in various needs. In order to meet the special functional requirements of various industries, it is necessary to improve the existing wires and cables and prepare cables with corresponding functions to meet the growing market needs. [0004] Aerial cables are the main transmission tool for power transmission. Carbon fiber cables are favored by the market for their light weight, high temperature resistance, corrosion resistance, and large transmission capacity. At present, carbon fiber cables are the development trend of th...
