Novel structure cable and manufacturing method

Abstract

The invention belongs to the technical field of power and cables and particularly relates to a novel structure cable. The novel structure cable comprises a conductor, an isolation layer and a sheath layer and is characterized in that multiple filling strips are arranged on the outside of the conductor, gaps are reserved among adjacent filling strips, the filling strips are wrapped by the isolation layer, and the sheath layer is extruded and wrapped on the isolation layer. The filling strips adhere to the surface of the conductor. The invention further discloses a manufacturing method of the novel structure cable. The novel structure cable has the main following advantages that under the condition of the same current carrying capacity, the outer diameter is smaller, material consumption is lower, and the price is lower; the heat radiating performance of the cable is excellent; the manufacturing method is simple and easy to master.

Description

technical field [0001] The invention belongs to the technical field of electric power and cables, and in particular relates to a novel structural cable and a manufacturing method. Background technique [0002] As an important pillar industry of the national economy, wire and cable accounts for an increasing proportion of the national economy. As a relatively mature industry, the cost reduction of wire and cable is also more and more valued by the industry. The cable structure is more divided into two levels, and the first level is highly integrated and complicated. It integrates multiple functions into one, saving laying, Operation and maintenance costs; the other level is structural simplification. In the case of meeting industry standards, national standards, and enterprise standards, the structure should be as simple as possible and the cost as low as possible. This method meets the requirements of a low-carbon environment. For this reason, domestic has carried out a lar...

[0004] The patent with the publication number CN103928135A discloses a multi-core cable, including a central conductor and multiple conductors, the central conductor is covered with an insulating layer, and the multiple conductors Surrounding the central conductor, and multiple conductors are covered with fan-shaped insulating layers, between the insulating layer outside the central conductor and the insulating layer outside the multiple conductors, and between the insulating layers outside the two adjacent conductors There are gaps between them, and the insulating layer outside the multiple conductors is covered with a sheath; it has a simple structure, and the fan-shaped insulating layer makes the protection more reliable, avoiding mutual interference between the inner conductors, and the insulating layer between the insulating layers. The gap improves the heat dissipation performance without adding any heat dissipation mechanism and reduces the cost, but the heat dissipation effect is still not ideal; CN103871577A patent discloses a high-strength and easy-to-dissipate flat cable, including an outer sheath, accommodating For at least two cores in the outer sheath, when the cable is in a straightened state, the central axes of all the cores are on the same plane, and the central axes of all the cores are kept parallel, The wire core includes a conductor layer, an insulation layer covering the conductor layer, a metal armor covering the insulation layer, and an inner sheath covering the metal armor, and the adjacent two sets of metal armor are fixed by metal reinforcing ribs, The adjacent two sets of inner sheaths are fixed by reinforcing ribs, the outer sheath is covered with reinforcing ribs, and the reinforcing ribs are covered with metal reinforcing ribs; although it can also achieve heat dissipation effect, there is still room for improvement in heat dissipation effect
