Problems solved by technology

When the cable extends into a closed space with various electrical components, this heat will not be dissipated and it will easily cause heat accumulation, resulting in safety hazards
[0003] And because some cables tend to bend in the narrow space, this brings difficulties to the installation of the heat loss device of the cable

Abstract

The invention relates to a cable having a fire-proof-layer-contained heat shield. The cable comprises a cylindrical cable body (9) arranged inside a heat shield and the heat shield containing an upper heat shield (8) and a lower heat shield (7). The shield walls of the upper heat shield (8) and the lower heat shield (7) include respective bottom walls (80 and 70) and side walls arranged at the two sides of the bottom walls (80 and 70); and the bottom walls (80 and 70) and two circular top parts opposite to each other at the diameter of the cable body (9) are in contact. Fire-proof layers (72) are arranged at contact surfaces between the bottom walls (80 and 70) and the two circular top parts opposite to each other at the diameter of the cable body (9); and the fire-proof layers (72) are made of fire-proof materials and play a role in fire prevention and heat insulation for the cable body (9). Besides, cooling fluid passageways (81 and 71) extending along the shield walls are respectively arranged in the shield walls.

Description

technical field [0001] The application relates to the field of cables, in particular to a cable with a fire-proof layer and a heat-insulating shield. Background technique [0002] Cables tend to emit a certain amount of heat during use. When the cable extends into a closed space with various electrical components, the heat will not be dissipated and will easily cause heat accumulation, thereby causing safety hazards. [0003] And because some cable bends tend to occur in the cable in the narrow space, this brings difficulty to the installation of the heat loss device of the cable. Contents of the invention [0004] The present invention consists in providing a cable with a heat-insulating shield with a fireproof layer, which overcomes the above-mentioned drawbacks. [0005] According to the present invention, a cable with a heat shield with a fireproof layer comprises a cylindrical cable body placed inside the heat shield and the said heat shield comprising an upper heat...
