scope:
This Defence Standard specifies the requirements for flexible cables and wires used for the interconnection of ground equipment, and for providing ground p:JWer supplies to aircraft, vehicles and other equipment used by the MD. All the cables and wires have an overall elastomeric sheath of heavy duty, heat resistant, oil resistant and flame retardant compound.
These cables and wires are suitable for use at voltages up to 500 V r.m.s. (where the conductor size is 2.5 mm2 or less), or 750 v r .m. s. (where the conductor size is 4 mm2 or greater), at frequencies up to 400 Hz, and where the combination of ambient temperature and temperature rise due to the current produces a stabilised conductor temperature not exceeding 85°C.
These cables and wires are suitable for deployment and recovery at temperatures down to -32°C.
This Standard covers five types of cables and wires, as follows:
cables, power, electrical (unscreened).Two to four cores inclusive.
Cables, power, electrical (collectively screened). Two, four or five cores.
Cables, power, electrical (unscreened). Two or four power cores. With additional monitoring or control cores.
cables, power, electrical (collectively screened). Two or four power cores. With additional 100nitoring core.
Wires, electrical.
A cross reference to the cables and wires formerly covered by the EL Specifications which have been superseded by this Standard appears in Annex A.
