How to prevent overheating of wire harnesses in space

November 23, 2015 Tristan Epp Schmidt

In the aircraft industry, a lot of effort goes into thermal management of the electrical wire interconnection system (EWIS). If not effectively managed, systems fail to operate and may lead to failures. A recent example of this is the case with the Boeing 787 battery issues (read the Report on Boeing 787 […] Read more

What is an aircraft wire Service Life Extension Program (SLEP)?

November 10, 2015 Lectromec Team

Over the years, the Lectromec website has received hundreds of thousands of visits. Often the topic of interest deals with Aircraft Wire Service Life Extension Programs. Because of this popularity, the Lectromec Podcast sat down with the president of Lectromec, Michael Traskos, to talk about Service Life Extension, or SLEP. During the interview Michael starts […] Read more

Completed aircraft wire harness testing

October 30, 2015 Michael Traskos

When it comes to examining aircraft wire systems, a lot of time is spent examining the performance of individual components like wires, cables, connectors, and pins. However, when we install complete aircraft wire harnesses, they must work in the fully assembled aircraft. They must endure the harsh conditions, various environments, and regular maintenance. To ensure […] Read more

What role does a humidity chamber play in an aircraft wire evaluation?

October 20, 2015 Lectromec Team

In our first installment of “Two Minute Tuesday” we have a two-minute video description of a humidity chamber and the role it plays in aircraft wire evaluation. We also take a look at testing one aspect of an aircraft wire – its ability to withstand variations in humidity and temperature. The long-term reliability of aircraft […] Read more

What does an aircraft wire testing lab look like?

October 13, 2015 John Gilroy

It is quite possible many aerospace professionals have never seen the inside of an aircraft wire testing lab. If you haven’t had a chance to see our lab, here we present a quick tour. Read more

Latest news on aircraft wire from the SAE’s Fall 2015 wire and cable committee meeting

October 1, 2015 Michael Traskos

The world of aircraft wire is rapidly changing. Lectromec attended this event and is providing a summary of the most current issues discussed during this fall’s SAE Wire and Cable Committee Meeting. Read more

What are the common tests for aircraft wire?

September 19, 2015 Michael Traskos

The hundreds of wire tests that exist for aircraft wire and cable can be categorized into five groups: environmental, electrical, mechanical, chemical, and thermal. In this series, we will look at common tests within each of these categories, what they are, how are they performed, and what the results mean. Read more

Understanding unexpected arc track resistance test results

September 12, 2015 Michael Traskos

Lectromec has been testing wire for the past thirty years. We have seen nearly every conceivable variation of aerospace wire testing. Some tests are straight forward and require little or no additional explanation of the test results; other tests require a fair bit of explanation to understand the test itself and what the results mean. Read more

What is the impact of increased electrical loads on aircraft wire systems?

September 4, 2015 Michael Traskos

With More Electric Aircraft (MEA) being the big push in the industry, it is important to take a moment and think about the wiring system that is going to be supporting these new designs. The following are some of the consequences resulting from an increased electrical load on the aircraft wire system: How much wire […] Read more

Aircraft secondary harness protection with Gregg Turcich

August 21, 2015 John Gilroy

Today Gregg Turcich sat down with Lectromec to discuss the topic of aircraft secondary harness protection, or what some call aerospace protective sleeves. Gregg is certainly qualified to talk about these topics because he has a degree in chemical engineering and decades of experience in aerospace technology. Gregg enumerates the four kinds of protection that […] Read more
