AI Technical Summary
Technical Problem
High-voltage cables are prone to freezing in low-temperature environments. Existing de-icing methods are costly or pose safety hazards and are difficult to efficiently remove ice from the outside of the cable.
Method used
A hollow ventilation channel is set inside the cable. In low-temperature environments, air at a suitable temperature is injected into the ventilation channel to melt the ice layer. The airbag core and cable wire structure enhance the stability and ease of splicing of the cable.
Benefits of technology
It improves the efficiency of dealing with icing on the outside of cables, reduces maintenance costs, reduces safety hazards, and enables convenient storage and splicing of cables.

Abstract
The invention relates to the technical field of cables, in particular to a preparation method of a high-voltage cable and the high-voltage cable. The method comprises the following steps that 1, a plurality of cable wires are installed on the peripheral side of an air bag core body; 2, packaging an outer sheath on the outer sides of the plurality of cable wires to obtain a cable with a standard length; 3, connecting a plurality of standard length cables one by one to obtain a high-voltage cable product; a main body of the cable is an air bag core body, a plurality of cable wires are installed on the peripheral side of the air bag core body, and a sheath is arranged on the outer sides of the cable wires; according to the invention, the hollow ventilation channel is arranged in the cable, and when the cable is in a low-temperature environment, air at a proper temperature is injected into the ventilation channel, so that an ice layer on the surface of the cable is melted, and the processing efficiency of the icing condition of the outer side of the cable is improved.
