Problems solved by technology

Of course, due to the use in the aerospace field, the requirements for anti-wave sleeves will be higher. Therefore, ordinary anti-wave sleeves often have problems such as breakdown when used in the aerospace field, which greatly increases their cost of use. And once it is applied in the aerospace field, the replacement becomes extremely complicated and unfavorable

Abstract

The invention discloses a high-temperature-resistant anti-wave cover for aviation. In the invention, a skin made of nano-silicon carbide, polyethylene resin, modified epoxy resin, carbon powder and nickel powder is attached to the surface of the braided wire, and the skin The ingredients are proportioned in a certain amount, so that the prepared skin has good high temperature resistance, and then the braided wire with the skin attached is braided to form a wave-proof sleeve. Of course, the braided wire here Materials can be prepared for conventional anti-wave sleeves such as conventional tinned annealed copper, so that the anti-wave sleeves made by the above materials and methods can still have good shielding effect while achieving high temperature resistance, thereby achieving better Excellent service performance, prolong service life, reduce maintenance costs, and meet aviation use. According to GB / T1408, the breakdown strength of this high-temperature anti-wave sleeve for aviation is 36-42kV / mm.

Description

technical field [0001] The invention relates to the technical field of cable preparation, in particular to a high temperature resistant wave-proof jacket for aviation. Background technique [0002] The anti-wave sleeve is a shielded copper braided sleeve used to prevent radio wave interference or protect. During the use of wires and cables, the anti-wave sleeve is mainly used to prevent radio wave interference or as a protective sleeve. plays a very important role. As an important shielding material, anti-wave sleeves are widely used in daily production, and are also widely used in many fields, such as aerospace and other fields. Of course, due to the use in the aerospace field, the requirements for the anti-wave sleeve will be higher. Therefore, the ordinary anti-wave sleeve often has problems such as breakdown when used in the aerospace field, thereby greatly increasing its use cost. And once applied in the aerospace field, the replacement also becomes extremely complica...
