Problems solved by technology

[0004] Among the relevant patents that have been applied in China, the patent "A Ceramic Insulated High Temperature Cable" (application number: 201520062210.3, publication date: 2015-07-08) discloses a ceramic layer coated on the surface of the conductor core material. Insulation method, but due to the continuous plating adopted, the ceramic film is very brittle, and the ceramic layer is easily broken after bending, and it is easy to damage the conductor core material and damage the insulating surface material, so that the service life of the final molded product is short, and it is also easy to age and corrosion

Abstract

The invention discloses an insulating material for high temperature resistant insulating cables and a method for preparing the same thereof. The insulating material can withstand long-term working temperature not lower than 150 DEG C and not higher than -50 DEG C, has a yield strength not lower than 80N / mm<2>, a ductility of not lower than 25 %, a volume resistivity of not lower than 2 X 1013 [Omega]cm, a dielectric strength of not lower than 500kV / cm. A ceramic fiber sleeve is made by applying sol-gel-lacing-sintering-molding technologies. According to the invention, the insulating material is ceramic based, anti-high temperature and anti-corrosion, and has long service life.

Description

technical field [0001] The invention relates to the field of electronic components, in particular to an insulating material for high-temperature-resistant insulating cables and a preparation method thereof. Background technique [0002] A cable is usually a rope-like cable twisted by several or groups of conductors (at least two in each group). Each group of conductors is insulated from each other and is often twisted around a center. Highly insulating overlay. The cable has the characteristics of internal electrification and external insulation. [0003] The insulating layer is to evenly and hermetically wrap a layer of non-conductive material around the cable conductor, such as: resin, plastic, silicone rubber, PVC, etc., but these materials are limited by their essential properties, and their heat resistance and insulation properties are compared with those of ceramics. Weaker than the base material. [0004] Among the relevant patents that have been applied in China, ...
