Description

Technical Field

[0001] The utility model relates to the technical field of power cables, in particular to a high-voltage thermally printed power cable. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. They play a vital role in the backbone lines of power systems and can be widely used in various fields of power systems, such as power stations, substations, urban power grids, etc. During the production of power cables, information such as manufacturer logo, specifications, etc. is printed on the cables by heating.

[0003] A Chinese patent discloses a multi-circuit high-voltage power cable (authorization announcement number CN208045173U). The patented technology is equipped with a heat-resistant sleeve, which uses a silicone layer as a carrier to conduct heat into the heat shrink layer for dilution, and the flame retardant layer performs flame retardant work. The thick coating can not only play a good role in anti-oxidation and anti-corrosion, but also has a heat insulation effect, ensuring the normal transmission of electricity, avoiding heat generation, and improving the dielectric properties of the cable.

[0004] However, most existing cables use flame-retardant insulation for heat dissipation, which prevents the heat generated by the cable's conductors during operation from dissipating, shortening the cable's service life. For example, the aforementioned reference document uses a flame-retardant coating. However, in actual use, heat is generated when the cable's conductors transmit power. If this heat is not dissipated, it can damage the cable. Therefore, those skilled in the art have provided a high-voltage thermally printed power cable to address the problems raised in the aforementioned background art. Utility Model Content
