What is BS EN 4612-009 - Silver plated copper cables about ?
BS EN 4612‑009 is an international standard on silver-plated copper cables.
BS EN 4612‑009 specifies the characteristics of UV laser printable jacket, silver-plated copper conductor, electrical cables Crosslinked Ethylene Tetra Fluoro Ethylene co-polymer XLETFE family for use in the onboard electrical systems of aircraft at operating temperatures between – 65 °C and 150 °C, operating at voltages not exceeding 600 V. 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.
Silver-plating makes the cable more ductile and enhances its life and are safe to use.
Who is BS EN 4612-009 - Silver plated copper cables for ?
BS EN 4612-009 on silver-plated electrical cables (Dual extruded wall for open applications) for aerospace applications is applicable to:
- Manufacturers of silver-plated electrical cables
- Aircraft manufacturers
- Quality control/testing and compliance personnel for aerospace
- Design engineers of silver-plated copper cables
- Aerospace and defence industries
- Testing agencies involved in the inspection of spacecraft and aerospace products
Why should you use BS EN 4612-009 - Silver plated copper ?
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 makes it safe to use. It also extends the life of the cable. 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 4612-009 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 4612-009 for inspection of surface, insulation, fire, and overload resistance. Thus BS EN 4612-009 can help in ease of production and increases the machining accuracy of the cable.
