What is TKT Insulated Wire?

On April 3rd 2017, you read about the Advantages of Kapton Insulated Wire. Then, on April 24th 2017, you read about the Disadvantages of Kapton Insulated Wire. Today, you will learn about another wire type commonly used on commercial and military aircraft. This wire has a tape-wrapped construction consisting of one layer of fluropolymer-polyimide- fluropolymer and a second layer of polytetraflouroethylene (PTFE). This construction is commonly referred to as TKT (Teflon-KAPTON-Teflon). TKT has been installed in aircraft since the early 1990s.  It is widely used as a replacement for Kapton wire.  Aged Kapton wire began experiencing many problems mainly due to abrasion and cracking beginning in the 1980s and continues to this very day. The US Navy, Air Force, Army, and Coast Guard have all had programs to remove their old wiring and replace it with TKT. InterConnect Wiring has assisted with those programs and continues to help our armed forces today as well as our NATO allies. If you have old wiring and are not sure what type it is, what the current state of the wire is, or if you would like to have it tested, send it to InterConnect Wiring at 5024 W. Vickery Blvd., Fort Worth, TX 76107 USA. We will provide you with the information you need.
