Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to a flexible mineral fireproof cable with high insulation performance. Background Art

[0002] If a traditional cable is disconnected during use, it will cause problems in the transmission of electricity. At this time, a new cable needs to be pulled and installed, which is time-consuming and labor-intensive. In addition, traditional cables are single-line transmission structures. If different lines need to be connected separately, multiple cables are required, which will increase the cost of the project. Therefore, the utility model provides a flexible mineral high-insulation fire-resistant cable to solve the above two problems. Utility Model Content

[0003] The utility model aims to provide a flexible mineral high-insulation fireproof cable to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a flexible mineral high-insulation fire-resistant cable, comprising a trunk cable, a branch cable and a cable sheath, the cable sheath being provided with branch parts at intervals, the trunk cable being arranged in the cable sheath, and the branch cable being bent and arranged in the branch part, and a cover being provided at the port of the branch part.

[0005] The outer jackets of the trunk cable and the branch cable are both flexible mineral layers.

[0006] A fireproof filler layer is provided between the trunk cable, the branch cable, the cable sheath and the branch part.

[0007] The sealing cover is installed at the port of the branch part by threading.

[0008] The sealing cover is provided with a protrusion.

[0009] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0010] 1. The utility model is provided with a trunk cable and a branch cable, and the branch cable is connected to the trunk cable. If the cable is disconnected during use, the branch cable can be pulled out and continued to be used, without the need to re-pull the cable for installation, which saves time and effort and has good effect;

[0011] 2. The utility model is provided with a trunk cable and a branch cable, and the branch cable is connected to the trunk cable. Through the setting of the branch structure, when the cables need to be connected to different lines respectively, it is only necessary to connect multiple branch cables to different lines, without multiple cables, thereby reducing the cost of the project;

[0012] 3. The utility model has branch parts at intervals on the cable sheath, and the branch cables are bent and arranged in the branch parts. When the branch cables are not in use, the branch cables can be arranged in the branch parts. When the branch cables are needed, the cover can be opened and the branch cables can be pulled out for use.

[0013] 4. The jackets of the trunk cable and branch cable of the utility model are both flexible mineral layers, and fireproof filler layers are provided between the trunk cable, branch cable, cable sheaths, and branch parts. The settings of these structures improve the flame retardant effect of the cable. BRIEF DESCRIPTION OF THE DRAWINGS
