A wall-attached self-defining form strong current cable

Abstract

The invention discloses a wall-laminated self-setting type strong-power cable and belongs to the technical field of cables. A wall-laminated self-setting type strong-power cable can be laid on the surface of a wall conveniently, the adsorption characteristic of a nanometer sucker is utilized, the cable is indirectly fixed for a long time under the action of the atmospheric pressure, effective fixing is realized under the condition of not damaging the cable, under the auxiliary action of liquid water and high-viscosity viscous liquid, the sealing performance of the nanometer sucker is improvedand the adsorption strength is further improved, a damping energy dissipation function is provided to counteract external force, meanwhile, the memory characteristic of shape memory alloy is used forhelping the cable to achieve self-setting, the laying mode is simple and fast, the lines laminated to the wall are straight, the aesthetic degree is remarkably improved, the cable is excellent in electrical insulation performance, high-temperature resistance and mechanical strength, and the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of cables, more specifically, to a wall-attached self-defining strong-current cable. Background technique [0002] Definition 1 of a cable: It is made of one or more mutually insulated conductors and an outer insulating layer, and the wire that transmits power or information from one place to another; Definition 2: Usually it is made of several or several groups of wires (Each group of at least two) twisted rope-like cables, each group of conductors are insulated from each other, and are often twisted around a center, the entire outer surface is covered with a highly insulating covering, and the cable has internal energization, Characteristics of external insulation. [0003] Strong electricity refers to the electric power part of the electrician field. It is characterized by high power, high current, and low frequency. It mainly considers the problem of low loss and high efficiency. It is closely related t...

Problems solved by technology

Reasonable selection of the cable laying method is very important to ensure the transmission quality, reliability and construction maintenance of the line. One way of laying a strong electric cable is called an open laying line. There are two types of open laying lines: one is through The protective tube is laid along the wall; the other is laid along the wall without the protective tube. The laying along the wall without the protective tube is relatively common because of its low cost and simple laying. holes and needs to be fixed in multiple places, which not only affects the aesthetics of the wall, but also takes a lot of time, and the safety is not guaranteed. When the fixing force is large, it is easy to cause damage to the cable, and when the fixing force is small, the cable is loose. It is difficult to control the fixing strength of the wire clamp
