<<Mr. Ingram: Kapton wiring is not used in the Yellow Gate system on the Nimrod aircraft but KTCL, a hybrid Kapton wiring, was introduced on the Nimrod MR2 as a part of the Yellow Gate modification programme during the period 1980 to 1985. The wiring used in the electrical systems of the Nimrod MR2 and Rl consists of: Nyvin, Minyvin, Efglas, KTCL, Febsil, ACT260, Raychem 44A and Raychem 55A.>>
This appears to open up other questions. Searching for each of these wiring types throws up some interesting links.
A link to the technical specification shows that Nyvin dates from 1961 and Minyvin from 1980.

The link shows Nyvin and its replacement Raychem 55 now being fitted to the Vulcan to the Skies.

The most interesting link is
http://www.caa.co.uk/docs/33/AIL0140.PDF which refers to Minyvin and the possibilty of arc tracking, sheath damage and fluid contamination.
The CAA link refers to EFGLAS and how it should be used to replace Minyvin. It also lists Nyvin, Minyvin, and KTCL as obsolete. It lists both Raychem 44 and 55.
A quick search did not turn up Febsil or ATC 260.
I think the Nyvin/Minyvin information is interesting.
