Def Stan wires are extensively used by the Ministry of Defence (MoD) in applications requiring high-density wiring within instruments and to connect electronic equipment. These flexible multi-core cables are used in aircraft, process control systems, computers, data processors, military vehicles and military equipment. As a high-grade, high-specification, compact cable, this range can also be used outside of the Defence industry.

Both Def Stan Part 4 and Part 5 cables have a Tinned Copper Wire Braid (TCWB) screening, providing protection against outside electrical interference. Part 4 cables are screened sub-miniature multi-core cables; Part 5 cables are special purpose small multi-core cables. Def Stan Part 6 cables are unscreened flexible equipment wires.

Defence standard cables have their origin in military applications but many have now crossed into industrial enviroments & applications. They cover a huge range of constructions and material compouds however we list the most common ones below.
