Silicone rubber insulated conductor with a woven fiberglass sheath is the
most used wire for interconnections. For thermal insulation I use ceramic
fibre blanket, 1" - 2" thickness. For elements, I wound coils using 16 AWG
Kanthal A -1 resistance wire from TEMCo 159 ft good for up to 2,500F.
Hope this helps you.
Cheers Graham
