Embodiment Construction

[0017] see figure 1 , a multi-core cable, including a center conductor 1 and a plurality of conductors 2, the center conductor 1 is covered with an insulating layer 3, the plurality of conductors 2 surround the center conductor 1, and the plurality of conductors 2 are respectively covered There is an insulating layer 4 with a fan-shaped cross section. There are gaps between the insulating layer 3 outside the central conductor 1 and the insulating layer 4 outside the multiple conductors 2 and between the insulating layers outside the two adjacent conductors. The insulating layer 4 is covered with a sheath 5 .

[0018] In the present invention, there is a gap between the insulating layer outside the plurality of conductors 2 and the sheath 5 .

[0019] The material of the sheath 5 is made of the following raw materials by weight (kg): high-density polyethylene 75, polyphenylene sulfide 15, polyethylene terephthalate 10, antimony trioxide 14, zinc borate 8, carbon black N66025,...

Abstract

The invention discloses a multi-core cable. The multi-core cable comprises a central conductor and a plurality of conductors. An insulating layer is wrapped outside the central conductor. The multiple conductors surround the central conductor. An insulating layer with a fan-shaped section is wrapped outside each conductor. A gap is reserved between the insulating layer outside the central conductor and the insulating layer outside each conductor. A gap is also reserved between the insulating layers outside every two adjacent conductors. A sheath is wrapped outside the insulating layers of the conductors. According to the multi-core cable, the structure is simple, the insulating layers with the fan-shaped sections make protection more reliable, mutual interference between the inner conductors is avoided, the gaps between the insulating layers improve the heat dissipation performance on the premise that no heat dissipation mechanism is additionally arranged, and cost is low.

Description

technical field [0001] The invention relates to the field of cables, in particular to a multi-core cable. Background technique [0002] Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0003] In the prior art, different types of conductors in the cable are twisted with each other. Although isolation or insulation measures are taken, they are still prone to mutual interference. At the same time, different types of conductors are twisted with each other, which also affects the heat dissipation performance. Traditional cable sheathing materials have the disadvantage of poor water resistance. Contents of the invention [0004] The purpose of the prese...
