Example Embodiment

[0035] The method for preparing a new type of electric vehicle internal cable includes the following steps:

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

[0037] (2) Pull out the required number of flat rectangular copper strip conductors through the pay-off rack with tension control and stack them up and down neatly. Ensure that the stacking is neat, and then pass through a special inner mold and outer mold to form an extrusion The extruder of the mold is extruded at a temperature of 135 to 165 degrees and a speed of 30-80 m / min. At the same time, a crawler tractor is used to draw out the extruded wire body.

[0038] (3) Use the cross-linking dose of 12-18 MRD, and use the electron beam physical cross-linking method to irradiate the cross-linked polyolefin insulation of the insulating layer at 150°C.

Example Embodiment

[0039] Example one:

[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) Select copper materials to process a single flat rectangular copper strip conductor that meets the size requirements, and process it into a thickness: 0.8mm, width: 30mm.

[0042] (2) Pull out the three flat square copper strip conductors through the pay-off rack with tension control and overlap them up and down neatly. To ensure the stacking is neat, they are then extruded by a special inner mold and an outer mold to form an extrusion mold. The machine is extruded at a temperature of 135 to 165 degrees and a speed of 30-80 m / min. At the same time, a crawler tractor is used to draw out the extruded wire.

[0043] (3) Use the cross-linking dose of 12-18 MRD, and use the electron beam physical cross-linking method to irradiate the cross-linked polyolefin insulation of the insulating layer at 150°C.

Example Embodiment

[0048] Embodiment two:

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

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

[0051] (2) Pull out 20 flat square copper strip conductors through a pay-off rack with tension control and overlap them up and down neatly. Ensure that the stacking is neat, and then pass through a special inner mold and outer mold to form an extrusion die. The extruder is extruded at a temperature of 135-165 degrees and a speed of 30-80 m / min. At the same time, a crawler tractor is used to draw out the extruded wire.

[0052] (3) Use the cross-linking dose of 12-18 MRD, and use the electron beam physical cross-linking method to irradiate the cross-linked polyolefin insulation of the insulating layer at 150°C.

[0053] During production, the height of the flat ...

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.

Description

technical field [0001] The invention relates to cables and wires, in particular to a cable used for connecting electrical appliances inside an electric vehicle. Background technique [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°C to 105°C, adhesion will occur at high temperatures of 110°C to 150°C, which may easily cause safety accidents. It takes up a lot of space when it is connected and used, and it is not easy to install. [0003] With...
