The basic requirements of aerospace cables are light weight, small diameter, high temperature resistance and good wear resistance. In addition, they should be resistant to fuel oil, lubricating oil and other chemical solvents. At present, my country’s aerospace cables adopt the national military standard GJB 773A-2000 “General Specification for Fluoropolymer Insulated Wires and Cables for Aerospace Use” as the main system. This specification applies to fluoropolymer insulated wire and cable products (hereinafter referred to as aviation cables), PTFE, FEP, PVDF, ETFE, XETFE, PFA and other fluoropolymers. These polymers can be used alone or in combination with other materials.
