Problems solved by technology

[0005] The length of the service life of the cable depends on the quality of the cable and the environment in which the cable is installed, and the biggest environmental factor is the temperature. Only in the appropriate operating temperature range can the cable perform its performance, and the temperature is too high or too low It will seriously affect the service life of the cable. At present, the cable itself cannot adjust itself according to the external temperature environment. Therefore, when faced with extreme temperatures, the cable is easy to cause damage, including high temperature burning or low temperature cracking.

Abstract

The invention discloses a double-scale self-regulating temperature cable based on dynamic changes, which belongs to the field of cable technology, and can realize autonomous action through the thermal insulation scale layer on the surface by imitating temperature-changing animals and according to changes in the external temperature environment. The open part of the area is connected to the outside world, and the heat inside the cable is gathered and then exchanged through the preset inner temperature control ring, which can dissipate the heat generated during the use of the cable, and at the same time collect rainwater to assist Dissipate heat and prevent rainwater from entering the cable for erosion. Once the low temperature is sensed, the deformation action of the insulation scale layer will be triggered, and a tight and fully enclosed scale layer will be formed on the surface of the cable to block the cold intrusion from the external environment. The incoming air undergoes self-heating reaction, which improves the thermal insulation effect on the cable, and can realize the use of self-regulation method to extend the service life of the cable.

Description

technical field [0001] The invention relates to the technical field of cables, more specifically, to a double-scale self-regulating temperature cable based on dynamic changes. Background technique [0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires, which have different definitions. [0003] Definition 1: A wire made of one or more mutually insulated conductors and an outer insulating layer to transmit power or information from one place to another. [0004] Definition 2: A rope-like cable usually twisted by several or groups of wires (at least two in each group), each group of wires is insulated from each other, and is often twisted around a center, and the entire outer wrap Has a highly insulating covering. The cable has the characteristics of internal electrification and external insulation. [0005] The length of the service life of the cable depends on the quality of the cable and the environm...
