Background

A cable is generally a cable made by twisting several or several groups of wires, each group of wires being insulated from each other and often twisted around a center, and being entirely covered with a highly insulating covering, and the cable being characterized by internal current conduction and external insulation. A cable is a material used for power, communication and related transmission applications, and must ensure that the working performance during operation is maintained within a stable range, with the main factors affecting the working performance including temperature and mechanical strength. A wire made of one or more mutually insulated conductors and an outer insulating protective layer for transmitting power or information from one place to another; the cable includes power cable, control cable, compensation cable, shielding cable, high temperature cable, computer cable, signal cable, coaxial cable, fire-resistant cable, marine cable, mining cable, aluminum alloy cable, etc.; the manufacture of wire and cable is quite different from the way most electromechanical products are produced. Electromechanical products typically employ the assembly of parts into components, and the reassembly of multiple parts into a single product, with the product being metered in units or pieces. The wire and cable are in basic unit of measurement of length. All the electric wires and cables are made by processing conductors, and adding insulation, shielding, cabling, sheath and the like layer by layer on the periphery of the conductors to form electric wire and cable products. The more complex the product structure is, the more levels are superimposed; various devices in a production workshop must be reasonably arranged according to the technological process required by the product, so that semi-finished products in each stage are circulated in sequence. The equipment configuration is to balance the production capacity in consideration of the difference in production efficiency, and some equipment may have to be configured with two or more equipment to balance the production capacity of the production line. Therefore, the reasonable matching combination of the equipment and the arrangement of the production field must be balanced and comprehensively considered according to the product and the production capacity; the production organization management must be scientific, reasonable, precise, strict and careful, an operator must be executed according to the process requirements at a glance, and any link with problems can affect the smoothness of the process flow and the quality and delivery of the product. Especially, in the case of a multi-core cable, if a certain line pair or basic unit is short in length or the quality is in problem, the length of the whole cable is insufficient, and the cable is scrapped. Conversely, if a unit length is too long, it must be sawn off, which is wasteful.

The prior art has the following defects: the existing cable is easily influenced by the external temperature, and the cable cannot be maintained in a high-performance state due to the frequently changed external temperature; the cable is usually protected by an insulating layer coated outside, but the mechanical strength of the cable is too low, and the cable is damaged if a mechanical impact with larger strength is encountered.

Therefore, it is necessary to develop a high temperature resistant electric wire and cable.
