Specification for electric cables for general airframe or equipment interconnect use (135°C), extruded insulation
This British Standard specifies construction and performance requirements for a range of lightweight and extra-lightweight cables (designated/EL) with extruded insulation suitable for general airframe use in all sizes.
The cables are also suitable for equipment interconnect use in the size ranges 26 to 18 (standard lightweight cable) and 24 to 14 (extra-lightweight cable).
The following types of cables are specified:
The cables are suitable for continuous use, where the maximum stabilized conductor temperature does not exceed 135 °C, and 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, and may also be used as the basis for cables having additional protection such as a jacket or screen and jacket. 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 continuous and short-term current ratings for the cables are specified in this standard.
NOTE 1 The titles of the publications referred to in this standard are listed on the inside back cover.
NOTE 2 The latest revision of an Aerospace Series standard is indicated by a prefix number.
Includes an additional range of extra-lightweight insulated cables for general airframe or equipment interconnect use.
