BS EN 4612‑008 is an international standard on silver-plated copper cables with jackets and screens.
BS EN 4612‑008 specifies the characteristics of UV laser printable jacket, silver-plated copper conductor, electrical cables Crosslinked Ethylene Tetra Fluoro Ethylene copolymer (XLETFE) family for use in the onboard electrical systems of aircraft operating at temperatures between 65 °C and 150 °C, operating at voltages not exceeding 600 V rms at sea level. This insulation system has been used in aerospace applications using 115 V (phase-to-neutral) 400 Hz ac and 28 Vdc.
These cables are suitable for airframe use without additional protection when the jacket is present. When the jacket is stripped back the cores may need additional protection. Silver-plating makes the cable more ductile and enhances its life, making it safe to use.
BS EN 4612-008 on silver-plated electrical cables (Single extruded wall for open applications) for aerospace applications is applicable to:
Silver-plated copper electrical cables have high tolerability of heat. They are heat and damage resistant. Copper, being a ductile metal gets more ductile by adding a layer of silver and enhancing its properties and influencing the use of the product throughout various industries together with enhancing the appearance and lustre of the wires.
The silver plating on copper is safe to use. It also increases the wire’s ductility, and it extends the life of the cable. Hence, BS EN 4612-008 is essential in getting the detailed specification on silver-plated copper cables.
Crosslinked Ethylene Tetra Fluoro Ethylene copolymer (XLETFE) greatly improves the surface resistance, insulation resistance, fire resistance of the cable, and tensile strength of the whole body of the cable. BS EN 4612-008 contains characteristics of silver-plated electrical cables (XLETFE) and provides essential guidance on using the electrical systems of aircraft.
As a quality control personnel, you can use BS EN 4612-008 for inspection of surface, insulation, fire, and overload resistance. Thus, BS EN 4612-008 can help in ease of production and guarantees the machining accuracy of the cable.
