Problems solved by technology

[0002] Cables are used in many occasions. Therefore, those exposed cables, because the cables themselves are not fireproof, are easily burned in the event of a fire or a fire source, resulting in economic losses.
The current cables are only treated with fireproof interlayers, or coated with fireproof paint. Although these methods can prevent fire and protect the inner core wires for a while, after a long time, the fireproof layer is carbonized and burned through, and the internal core The wire will still suffer from flame erosion

Embodiment Construction

[0022] Such as figure 1 and figure 2 As shown, the composite fireproof cable includes more than one assembled cable and a cable body formed by splicing more than one connector 1, the cable body is suspended from the top and installed, and each assembled cable includes the first outer layer 2 and the second Two outer layers 23, the first outer layer 2 and the second outer layer 23 are spliced ​​into a circular cable outer layer;

[0023] Both end faces of the first outer covering layer 2 and the second outer covering layer 23 are rotatably connected to the connecting piece 1 through a rotating structure, and a through hole 101 is opened in the middle of the connecting piece 1, and a cable is formed in the middle of the outer covering layer of the cable. The installation cavity, the cable core wire 4 is arranged in the cable installation cavity and passes through the through holes of the connectors 1, the cable core is supported by the connectors 1, and the opposite surfaces o...

Abstract

The invention discloses a composite fireproof cable which comprises a cable main body formed by splicing one or more assembly cables and one or more connecting pieces. The cable main body is installedby suspending at the top. Each assembly cable comprises a first outer coating layer and a second outer coating layer, the first outer coating layer and the second outer coating layer are spliced intoa circular cable outer coating layer, the end faces of the two sides of the first outer coating layer and the second outer coating layer are rotationally connected with the connecting pieces throughrotating structures, and through holes are formed in the middles of the connecting pieces. As long as the cable is applied to a high position, the cable has very good protection performance and can automatically fall off after resisting burning of a flame cup, a new outer coating layer can be immediately replaced to continue to protect a cable core at the top, and flame is prevented from being transmitted to the cable core end.

Description

technical field [0001] The invention relates to a cable, in particular to a composite fireproof cable. Background technique [0002] Cables are used in many occasions. Therefore, those exposed cables are easy to be burned in the event of a fire or a fire source because the cables themselves are not fireproof, resulting in economic losses. The current cables are only treated with fireproof interlayers or coated with fireproof paint. Although these methods can prevent fire and protect the inner core wires for a while, after a long time, the fireproof layer is carbonized and burned through. The wire is still subject to flame erosion. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a composite fireproof cable, which can realize the automatic shedding of the outer layer after being eroded by flames for a period of time, and can quickly make up the outer layer on the other side, so as to win more for fire extinguishin...
