What type of cable is this???

[weressl]

From this description, I would go one step further and say these cables are definitely feeding a Rockwell Systems Retroencabulator! :grin:

I see the problem now, I think. The different insulation is not on a single cable, they each represent - separated by commas - and insulation system of different cables progressively higher and higher temperature tolerance.

It should have read:

These seem to be high temperature insulation systems. It could be either glass fiber (GF) braided jacket or Teflon impregnated GF with Teflon jacket underneath or fiberglass reinforced Mica tape with GF braided overjacket, with Ni plated copper stranded conductors used for the "cold" lead-in section of electrical resistance heaters or trasnfomer internal wiring. 150-450 Centigrade range.

I can't understand how people imagine of learning things from books without having a discourse with someone knowledgable about the subject.

That's why school was so tuf for me. If I couldn't handle/see it demonstrated it, I couldn't understand it.

Sometimes I sit and listen to people at conferences and it amazes me that they are missing the fundamentals adn construe the missing parts by guesswork. This includes acknowledged experts, senior IEEE fellows and so on. Amazing, but true....

All I can do is nod my head <yes> and laugh!
