Ultra-flexible shielding high-voltage wire for electric automobile

Abstract

The invention discloses an ultra-flexible shielding high-voltage wire for an electric automobile. The ultra-flexible shielding high-voltage wire comprises a cable conductor, a connecting wrapping tape, an insulating sheath, a shielding tape and an outer sheath which are sequentially wrapped from inside to outside, the cable conductor is formed by twisting a central copper wire and six external copper wires located outside the central copper wire, and an insulating layer is sleeved outside the cable conductor. According to the ultra-flexible shielding high-voltage wire for the electric automobile, a weaving process for weaving the copper wires is determined, so that a better shielding effect and a better soft effect are obtained; through the arrangement of the composite sheath, the outer sheath which is high in strength, better in flexibility, stronger in light aging resistance and better in oil resistance is obtained, the service life of the outer sheath is prolonged, and the cable is suitable for production, processing and use of actual high-voltage wires.

Description

technical field [0001] The invention belongs to the technical field of cable production and processing, in particular to an ultra-flexible shielded high-voltage wire for electric vehicles. Background technique [0002] The high-voltage cable in the car is used to connect the charging port and the battery, the interior of the battery, the battery and the engine and other components. It is the carrier of power transmission and is very important. The shielding layer of the existing high-voltage line is generally in the form of metal shielding, which is usually divided into aluminum tube / copper tube, parallel sparsely wound copper wire and braided copper wire. Braided copper wire is carried out, and the braiding process of braided copper wire also has a certain influence on the shielding effect. The outer sheath of the existing high-voltage line is generally made of polyvinyl chloride (PVC) material, which has high density, low light-aging resistance, and poor oil resistance. ...

AI Technical Summary

Problems solved by technology

The shielding layer of existing high-voltage lines is generally in the form of metal shielding, usually divided into aluminum tubes / copper tubes, parallel sparsely wound copper wires and braided copper wires. Due to the poor fatigue resistance of parallel sparsely wound copper wires, generally adopt Braided copper wire, and the weaving process of braided copper wire also has a certain influence on the shielding effect

The outer sheath of the existing high-voltage line is generally made of polyvinyl chloride (PVC), which has a high density, low light aging resistance, and poor oil resistance.
