High-voltage connecting cable with ultra-soft aluminum conductor and for interior of electric automobile and manufacturing method

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 to 120 mm ; 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.
