[0003] When the overhead cable in the prior art is in use, if there is a fault, the cable will leak electricity in a local area, and a large amount of heat will be accumulated in the damaged part. If it is not handled in time, the cable will be damaged, and this local area leakage The situation is generally difficult to see, and the inspectors may ignore it. In order to warn the inspectors, we propose an overhead insulated cable

The invention discloses an overhead insulated cable, which comprises a first cable and a second cable, the first cable and the second cable are connected through a bushing, and the first cable and the second cable are equipped with multiple a plurality of embedded tubes in the first cable and a plurality of embedded tubes in the second cable communicate with each other through a connecting tube, and the two built-in triangular tubes There are a plurality of cable bodies running through the tube, and a device column is provided at the side wall of the sleeve, and the device column is fixedly connected with the side wall of the sleeve through a fixing device, and a movable cavity is provided through the device column , a warning mechanism is slidingly provided in the movable chamber, and the surface layer of the built-in triangular tube is composed of an anti-collision rubber layer, a moisture absorption layer, a buffer layer and a heat transfer layer. The invention has a reasonable structural design and has the advantages of being able to warn inspectors and discover cable faults in time.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to an overhead insulated cable. Background technique [0002] Aerial cables are overhead wires with insulating layers and protective sheaths. They are a special cable manufactured by a production process similar to that of cross-linked cables. They are a new power transmission method between overhead wires and underground cables. [0003] When the overhead cables in the prior art are in use, if there is a fault, the cable will leak electricity in a local area, and a large amount of heat will be accumulated in the damaged part. If it is not handled in time, the cable will be damaged, and this local area leakage The situation is generally difficult to see, and the inspectors may ignore it. In order to warn the inspectors, we propose an overhead insulated cable. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings in the prior art, and ...
