Specifies the construction and performance requirements for a range of lightweight cables with wrapped insulation suitable for general airframe use in the size range 26 to 0000 and for equipment interconnect in the size range 26 to 18.

This British Standard specifies construction and performance requirements for a range of lightweight cables with wrapped insulation and silver plated conductors suitable for general airframe use in the size range 26 to 0000, and for equipment interconnect in the size range 26 to 18. The following types of cable are specified: The cables are suitable for continuous use where the maximum stabilized conductor temperature does not exceed 150 °C. They are suitable for applications involving flexing at temperatures down to − 65 °C. The cables are suitable for use where the potential between conductors or between a conductor and screen, or the aircraft structure does not exceed 600 V r.m.s. and the frequency does not exceed 2 000 Hz. Interconnect cables are suitable for use in areas with some physical protection, such as behind panels or bulkheads, They also have an application for the internal wiring of equipment. Airframe cables are of sufficiently robust construction to be used for open aircraft wiring. The short-term and long term current ratings for the cables are specified in this standard. NOTE The titles of the publications referred to in this standard are listed on the inside back cover.
