What is BS EN 4681-006 - Characteristics of electrical wires AZA family about ?
BS EN 4681-006 is European Standard on conductors in aluminium or copper-clad aluminium cables.
BS EN 4681-006 specifies the characteristics of electrical wires AZA family for use in the onboard:
- 115 V (phase to neutral) or 200 V (phase to phase) electrical network of aircraft
- 230 V (phase to neutral) or 400 V (phase to phase) electrical network of aircraft and particularly use in non-pressurized areas
This cable family is used at operating temperatures between − 65 °C and 180 °C.
Who is BS EN 4681-006 - Characteristics of electrical wires AZA family for ?
BS EN 4681-006 electrical wires AZA family for aerospace applications is applicable to:
- Manufacturers of electrical cables
- Aircraft manufacturers
- Quality control/testing and compliance personnel for aerospace
- Aerospace avionic and fibre optic technology
- Aerospace and defence industries
- Testing agencies involved in the inspection of spacecraft and aerospace products
Why should you use BS EN 4681-006- Characteristics of electrical wires AZA family ?
Copper and aluminium are widely used as electrical conductors in electrical cables due to their low resistance and excellent conductivity. These metals are both ductile and relatively resistant to corrosion.
BS EN 4681-006 specifies characteristics of electrical cables and provides best practice guidance on using the electrical wires in aircraft.
As a quality control personnel, you can use BS EN 4681-006 for inspection of surface, fire, humidity, and overload resistance of the cable, and tensile strength of the whole body of the cable. Thus BS EN 4681-006 can help in ease of production.
