GWIB (general way interface bus) high-temperature-resistant cable and preparation process thereof

Abstract

The invention discloses a GWIB (general way interface bus) high-temperature-resistant cable and a preparation process thereof. The GWIB high-temperature-resistant cable and the preparation process thereof are characterized in that a nickel-clad copper alloy line conductor is twisted by a cable wire twisting machine, inner insulating layers of two polyimide composite belts (PTFE(polyterafluoroethylene) / PI(polyimide) / PTFE(polyterafluoroethylene)) which are lapped by a lapping machine are arranged on the periphery of the nickel-clad copper alloy line conductor, a high-temperature-resistant alkali-free glass fiber outer insulating layer which is woven by a weaving machine is disposed on the periphery of each inner insulating layer, a lapping layer which is lapped by a mica tape is disposed onthe periphery of each outer insulating layer, and a high-temperature-resistant alkali-free glass fiber woven protecting layer which is woven by the weaving machine is arranged on the periphery of each lapping layer. The GWIB high-temperature-resistant cable and the preparation process thereof have the advantages that lapping and sintering process is adopted to realize insulation, combined insulation is adopted, the cable has excellent electric performances, mechanical performances and environmental resistance, is resistant to high temperature of 400 DEG C, is high-temperature-resistant, low-temperature-resistant, mould-resistant, salt-air-resistant, moist-heat-resistant and flexible, and is small in outer diameter and light in weight, and the like.

Description

Technical field:

[0001] The invention relates to a GWIB high-temperature-resistant cable and a preparation process thereof, which can be used as a cable for connection in high-temperature special environments such as around aircraft engines, and is mainly suitable for signal and energy transmission of electronic components in key parts of the aviation and aerospace fields. Background technique:

[0002] Various high-temperature wires and cables insulated by fluoroplastics are the most common in domestic and foreign markets, especially wire and cable products with XETFE as insulation and sheath materials, which are widely used in the aerospace field, but due to the limitations of XETFE materials themselves, The material is an insulated and sheathed cable, and its long-term working temperature can only reach 200°C, which cannot meet the requirements of a higher temperature working environment. The aviation industry needs a new product to fill this gap. We choose PTFE / PI / PTFE c...
