Abrasion-resistant and waterproof cable

Abstract

The invention discloses a wear-resistant watertight cable, comprising a cable main body and a server, wherein the cable main body comprises a wire core, a water absorbing layer, a filling space, a middle layer, the server and an external tube; the wire core comprises a plurality of leads and an insulating layer sleeving outside the leads; the water absorbing layer comprises a tubular inner sleeve and a tubular outer sleeve and the inner sleeve sleeves outside the wire core; the filling space is filled with activated carbon granules and super absorbent resin; the middle layer is a tube sleeving outside the water absorbing layer and is provided with a plurality of bumps on the outer surface, each pump is internally provided with a cavity, and a single-chip microcomputer, a transmitting device and a current sensor are arranged in each cavity; the server is in communication connection with the single-chip microcomputers; the external tube sleeves outside the middle layer. The cable is watertight and also capable of discovering and positioning an electric leakage position timely.

Description

technical field [0001] The invention relates to a wear-resistant and waterproof cable. Background technique [0002] With the development of our country's economy, our country's electric power and communication equipment have developed by leaps and bounds. Cables are often used in a humid working environment. In such an environment, water branches often appear on the cable. Excessive water branches will cause the cable to be interrupted during operation, increasing the loss of the cable, insulation resistance and breakdown. The voltage drop shortens the service life of the cable. The greater the humidity, the more water branches will be generated, and the performance of the cable will be seriously affected. Moreover, in the long-distance transmission, the cable length is longer. If there is a leakage in the middle, it cannot be found in time. position. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned proble...
