Novel wire and preparation method thereof

Abstract

The invention discloses a new type of wire, which includes a conductive core and a protective sheath, the protective sheath is wrapped around the conductive core, and the protective sheath is sequentially provided with an insulating layer, a flame-retardant layer, a shielding layer and an outer sheathing layer from the inside to the outside. ; The conductive core includes the following components by weight: 5-10 parts of carbon fiber rods, 50-70 parts of copper, 12-15 parts of zinc, 10-20 parts of manganese, 5-10 parts of aluminum, 3-3 parts of silver nanowires 5 parts, the insulating layer is made of modified ethylene-propylene insulation or cold-resistant soft elastomer, the flame-retardant layer is made of halogen-free low-smoke flame-retardant thermoplastic polyester elastomer TPEE, and the shielding layer is made of tin-plated soft-through braiding method, The outer sheath adopts cold-resistant nanocomposite elastomer. The wire has compact structure, light density, high electrical conductivity, super flexibility, bending resistance, twist resistance, wear resistance and good anti-interference performance.

Description

technical field [0001] The invention belongs to the technical field of wires, and in particular relates to a novel wire and a preparation method thereof. Background technique [0002] Copper alloy wires are mainly used in primary lines (copper alloy wires are used for high-current phase wires, neutral wires, and ground wires), and copper alloy wires are used for connecting primary components with large currents on electric cabinets. There are tin-plated copper alloy wires and bare copper alloy wires. In the electric cabinet, the joints of copper alloy wires are usually tinned and embossed or conductive paste is added. There is a heat shrinkable sleeve for protection in the spare space, and some are covered with insulating paint. The most important consideration when using copper alloy wire is the current carrying capacity. Select the appropriate copper alloy wire according to the current size, and the screws at the connection must be tightened, otherwise the copper alloy wi...

Problems solved by technology

However, it is still very difficult to achieve various indicators based on the existing technology.

[0004] The traditional wire is relatively simple because of the structure of the insulating sheath on the cable core. For the safety protection of the cable, external force pulling and maintenance are very troublesome.
