Problems solved by technology

[0002] Electric vehicles are mainly powered by batteries. The connection between the internal battery and the motor or between the charging socket and the battery in the electric vehicle has a large carrying capacity and high temperature. The existing products use round cables, and the conductor structure is A plurality of round copper wires are twisted together. During use, round cables have large dimensions, low temperature resistance, low longitudinal tear resistance, and poor flexibility. They are insulated with polyvinyl chloride, and the general temperature resistance is -20℃~105℃, adhesion will occur at high temperature of 110℃~150℃, which will easily cause safety accidents
It takes up a lot of space when it is connected and used, and it is not easy to install

preparation example Construction

[0035] Its a kind of preparation method of electric vehicle internal cable comprises the following steps:

[0036] (1) Use copper material to process a single flat square copper strip conductor that meets the size requirements, and process it into a thickness: 0.1-1.0mm, and a width: 10-50mm.

[0037] (2) Pull out the required number of flat square copper strip conductors through a tension-controlled pay-off frame and overlap them neatly together. To ensure that the stacks are neat, they are extruded through a special inner mold and outer mold. The extruder out of the mold is extruded at a temperature of 135-165 degrees and a speed of 30-80 m / min. At the same time, the crawler tractor is used to draw out the extruded wire body.

[0038] (3) The 150° C. crosslinked polyolefin insulation of the insulating layer is irradiated and crosslinked by using a crosslinking dose of 12 to 18 MRD and using an electron beam physical crosslinking method.

Embodiment 1

[0040] Now take three flat square copper strips, the size of a single copper strip is 0.8mm thick and 30mm wide as an example:

[0041] (1) Use copper material to process a single flat square copper strip conductor that meets the size requirements, and process it into a thickness of 0.8mm and a width of 30mm.

[0042] (2) Pull out three flat square copper strip conductors through a tension-controlled pay-off frame and overlap them neatly together. To ensure that the stacks are neat, they are extruded through an extrusion die that is equipped with a special inner mold and an outer mold. The extruder is extruded at a temperature of 135-165 degrees and a speed of 30-80 m / min. At the same time, the crawler tractor is used to draw out the extruded wire body.

[0043] (3) The 150° C. crosslinked polyolefin insulation of the insulating layer is irradiated and crosslinked by using a crosslinking dose of 12 to 18 MRD and using an electron beam physical crosslinking method.

Embodiment 2

[0049] Taking 20 flat square copper strips as an example, the size of a single copper strip is 0.1mm thick and 18mm wide:

[0050] (1) Use copper material to process a single flat square copper strip conductor that meets the size requirements, and process it into a thickness of 0.1mm and a width of 18mm.

[0051] (2) Pull out 20 flat square copper strip conductors through a tension-controlled pay-off stand and overlap them up and down neatly to ensure that the layers are neat, and then pass through the extruding mold with a special inner mold and outer mold. The extruder extrudes at a temperature of 135-165 degrees and a speed of 30-80 m / min, and at the same time uses a crawler tractor to draw out the extruded wire body.

[0052] (3) The 150° C. crosslinked polyolefin insulation of the insulating layer is irradiated and crosslinked by using a crosslinking dose of 12 to 18 MRD and using an electron beam physical crosslinking method.

Abstract

The invention provides a novel cable used in an electromobile and a preparation method of the cable. The cable comprises an insulator and a cladding conductor. The cable is characterized in that the conductor is formed by stacking a plurality of flat square copper strips; and the insulator is a crosslinked polyolefin insulator. With the cable in the structure above, the current-carrying capacity is large, heat radiation is achieved favorably, temperature resistance level is high, and the cable can be normally used at environment temperature of 150 DED C and the bellow. The cable is good in mechanical strength, softer and convenient to install and wire, convenient to produce and high in practicality; and the installation space is saved.
