High-temperature-resistant and high-voltage-resistant electric wire and preparation process thereof

Abstract

The invention discloses a high-temperature-resistant and high-voltage-resistant electric wire and a preparation process thereof. The high-temperature-resistant and high-voltage-resistant electric wirecomprises wire cores, a coating layer, a braided layer, a shielding layer and a sheath layer, wherein the three groups of wire cores are uniformly distributed at equal intervals in a circumferentialmanner, and are wrapped by the coating layer, the outer side of the coating layer is wrapped with the braided layer, the outer side of the braided layer is wrapped with the shielding layer, and the outer side of the shielding layer is wrapped with the sheath layer. According to the invention, the temperature resistance and the compression strength of the wire are enhanced, the service life of thewire is prolonged, and the safety coefficient of the wire is greatly improved.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a high temperature and high pressure resistant wire and a preparation process thereof. Background technique [0002] Electric wire is a wire product that transmits electric energy, electric signal and realizes the conversion of electromagnetic energy. It usually consists of a cable core that transmits electric power or electric signal and a sheath that plays a protective and insulating role. [0003] At present, with the development of science and technology, there are more and more needs and uses for wires; however, the quality requirements for wires are also getting higher and higher, and the thickness of the general wire core is small, and without any protective structure, it cannot Satisfy the use environment of high temperature resistance and high pressure resistance, which greatly reduces the service life of the wire. Therefore, the above problems urgently need to...
