a power transmission cable

Abstract

The invention discloses a power transmission cable, comprising an internal pressure mechanism, a cable sleeve is fixedly connected to the outer surface of the internal pressure mechanism, the cable sleeve is arranged in two layers, and a cable is movably connected between the double layers of the cable sleeve Line, the side of the cable sleeve away from the internal pressure mechanism is fixedly connected with the insect repelling mechanism, and the side of the insect repellent mechanism away from the cable sleeve is fixedly connected with a protective jacket; the cable sleeve includes an inner sleeve, and the inner sleeve is A ventilation hole is opened on the surface, the inner sleeve is located on the side away from the internal pressure mechanism and is fixedly connected with an auxiliary support tube, and the end of the auxiliary support tube away from the inner sleeve is fixedly connected with an outer sleeve, and the outer sleeve is away from the inner sleeve. An exhaust hole is provided on one side and in the middle of the auxiliary support pipe, and the invention relates to the technical field of electric power. The mechanism is controlled by the heat generated by the size of the current flow, and the overflow of the repellent liquid is controlled to be suitable for different environments and disperse different species.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a power transmission cable. Background technique [0002] A cable is a wire that transmits electricity or information from one place to another, made of one or more conductors insulated from each other and an outer insulating protective layer. Cables can be divided into DC cables and AC cables according to the system of photovoltaic power plants, which are used to transmit electrical energy, information and wire products to realize electromagnetic energy conversion. In a broad sense, wires and cables are also referred to as cables. [0003] According to Chinese patent CN106409411A, it includes a rubber layer, a solid insect repellent pill, a filling layer, an insulating layer, a wrapped pipe and a wire core, and a circular solid insect repellent pill is arranged inside the rubber layer. There is a filling layer in between, the inner side of the rubber layer is provided w...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a power transmission cable, which solves the problem that the existing power transmission cable cannot effectively control the overflow of insect repellent liquid during use, and cannot adjust the type of repellent, so it cannot be applied It is used in different environments, and it is difficult to maintain effectively. It needs to be replaced alternately, and the operation is cumbersome and inconvenient.
