What is BS EN 4681-005 - Characteristics of electrical wires AZ family about ?
BS EN 4681-005 is European Standard on conductors in aluminium or copper-clad aluminium cables.
BS EN 4681-005 specifies the characteristics of electrical wires AZ 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 4681-005 - Characteristics of electrical wires AZ family for ?
BS EN 4681-005 electrical wires AZ 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 4681-005 Characteristics of electrical wires AZ 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 4681-005 outlines 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 4681-005 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 4681-005 can help in ease of production.
