Flexible temperature control cable for airport charging and production process thereof

Abstract

The invention discloses a flexible temperature control cable for airport charging and a production process thereof. The flexible temperature control cable comprises a combined cable core. The combinedcable core comprises power line cores, auxiliary line cores, control wire harnesses and cable core fillers. The power wire cores are arranged around the axis center at 120 degrees; the auxiliary wirecores are disposed between adjacent power wire cores; and each control wire harness is disposed between the adjacent power wire core and the auxiliary wire core. Each power wire core comprises a combined conductor and a power wire core insulation layer. The combined conductor is formed by stranding a plurality of conductor bundles and a bundle of temperature-control wire core in a layered manner.The cable is compact in structure; the skin effect of the cable is reduced; the current carrying capacity of the cable is increased; heating of the cable is reduced; and a temperature control cable is stranded in the combined conductor, so that the current of the cable can be regulated according to the temperature, power transmission efficiency of the cable is improved, power transmission loss isreduced, charging speed is accelerated, cable operating temperature is reduced, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to cables, in particular to a flexible temperature-controlled cable for airport charging and a production process thereof. Background technique [0002] In order to reduce the overall weight of the aircraft and improve the internal space of the aircraft, the electrical components used are 400Hz AC. After the aircraft lands, the battery needs to be charged to ensure normal power supply. 400Hz AC is also used when charging. The skin effect will cause the AC resistance of the charging cable to increase, and at the same time generate a relatively large magnetic field, which reduces the current carrying capacity of the cable, slow charging of the cable, severe heat generation, and short life. Contents of the invention [0003] The object of the present invention is to provide a flexible temperature-controlled cable for airport charging with fast charging and long service life and its production process. [0004] The first technical ...
