1500V cable of charging pine of new energy electric automobile

Abstract

The invention discloses a 1500V cable of a charging pine of a new energy electric automobile. The cable comprises a cable core. A waterproof tape isolation layer is extruded out of the cable core. A jacket made of a 125 degrees centigrade anti-flaming thermoplastic elastomer is extruded out of the outmost layer of the cable. The cable core is composed of a Kevlar tensile rope arranged at a center, four power wires arranged around the Kevlar tensile rope, a ground wire, and detection signal wires which are symmetrically arranged at two sides of the ground wire. According to the cable, the rated voltage of the new energy source electric automobile charging cable is improved; moreover, the flexibility of the cable is ensured; through selection of a nylon insulation inner sheath, the insulation resistance among the voltage wires is improved, and the leakage current is reduced; moreover, through addition of the waterproof tape, the water vapour in the air is prevented from permeating into the cable; the new energy source electric automobile charging voltage is increased; the new energy source electric automobile charging time is shortened; the usage frequency is improved; and the usage inconvenience resulting from the long charging time is reduced.

Description

technical field [0001] The invention relates to the field of wires and cables, in particular to a 1500V new energy electric vehicle charging pile cable. Background technique [0002] With the vigorous promotion of new energy electric vehicles, the demand for special charging facilities for new energy electric vehicles has increased, but the car itself is a common means of transportation. At present, it takes a long time to charge new energy vehicles, generally 6 to 12 hours. , A one-time charge of 100-200 kilometers is a normal charge, and the charging time is too long, which directly affects the utilization rate of the car. For new energy vehicle manufacturers, to solve the problem of fast charging of vehicles, first solve the problem of charging facilities. Obviously, fast charging must increase the charging voltage, increase the charging voltage of new energy electric vehicles, improve the withstand voltage of cables, and maintain the same leakage current. The insulation...
