Use of Cables on Aircraft – Part 3 – Testing

To continue the series of articles on NEMA27500 cables discussing their use on aircraft (part 1 and 2), this article focuses on the several tests that are necessary for cable verification and certification. There is some level of performance verification for each part of an aircraft cable. Most cable assessment tests focus on the performance […] Read more

Use of Cables on Aircraft – Part 2

In this article, we will continue the discussion by exploring the NEMA27500 cable. Four sections were covered in the Part 1 (Specification, identification and shield coverage, conductor size, and wire specification). The remaining three parts covered here are the basic component wires, shielding materials, and the jacket materials. Read more

Use of Cables on Aircraft – Part 1

Electrical wire cables are an integral part of an aircraft’s Electrical Wire Interconnection System (EWIS). It would be difficult to imagine the design of an aircraft electrical system without the use of electrical cables. The use of cables in aircraft has simplified the formation of wire harnesses and installation of electrical components (think of the […] Read more

4 aspects of wiring selection for special aircraft applications

Not all wires are created equal. Through the years, Lectromec has learned the best practices for wire selection that would ensure the Electrical Wire Interconnect Systems’ (EWIS) longevity. There are thousands of wire standards for the aerospace industry. These include: the National Electrical Manufacturers’ Association (NEMA) standards, the Society of Automotive Engineers (SAE) standards, as […] Read more
