High-voltage connection cable for electric vehicle interior with ultra-flexible aluminum conductor and manufacturing method

Abstract

The invention belongs to the technical field of cables, and particularly relates to a high-voltage connecting cable with an ultra-soft aluminum conductor and for the interior of an electric automobile. The high-voltage connecting cable comprises the conductor, a wrapping belt, an insulating layer and a sheath layer and is characterized in that the conductor is formed by stranding annealed fifth-class soft aluminum wires with the diameter ranging from 0.10 mm to 0.45 mm, and the cross sectional area of the conductor ranges from 1.5 mm<2> to 120 mm<2>; both the insulating layer and the sheath layer are made of 125 DEG C environment-friendly antiflaming TPEs or 125 DEG C environment-friendly antiflaming irradiation crosslinking polyolefin, or the insulting layer is made of 125 DEG C environment-friendly antiflaming irradiation crosslinking polyolefin and the sheath layer is made of 125 DEG C environment-friendly antiflaming TPEs. The high-voltage connecting cable has the following advantages of being softer, easier to bend, lighter in dead weight, lower in cost, more resistant to high voltage and large current, better in antiflaming effect and safer in use.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a high-voltage connecting cable used inside an electric vehicle with an ultra-soft aluminum conductor and a manufacturing method. Background technique [0002] The high-voltage connection cable for automobile interior is a kind of power supply connection line, which is mainly used for high-voltage transmission inside the vehicle. Flexible cables for communication power supply not only require good flexibility to facilitate laying in narrow spaces or similar situations, but also require ideal flame retardancy to meet higher fire protection requirements. [0003] At present, most of the cables for automobiles at home and abroad use copper conductors, which are heavy and less flexible; flexible cables for communication power supplies are usually used as alternatives at home and abroad.

AI Technical Summary

Problems solved by technology

[0005] Although the flexible cables for communication power supplies in the prior art have corresponding technical effects, they have the following common defects: (1) because they are made of stranded fine copper Silk is used as a conductor, and its softness cannot meet the desired requirements

And due to the poor softness, the bending radius is limited, so when laying in a narrow space, obstructed by immovable objects or even corners, it is easy to affect the construction speed, especially in places with small spaces such as vehicles; (2) Because copper is generally used as the conductor of flexible cables under technical prejudice, there is not only blindness in the rational use of raw materials, but also the manufacturing cost of flexible cables is high; third, due to the high density of copper, the weight of cables is relatively high. Therefore, not only the cost of logistics transportation and warehousing is high, but also the labor intensity of the construction personnel during the laying process is high, and the labor cost is high
