Intro
Nichrome wire is used to make electric heaters. It heats up to a high temperature while retaining its strength. It is resistive, so it is easy to heat by sending electric current through the wire.
Nichrome wire is live with electric potential. It is useful to insulate it to use it reliably without shorting out on itself or on other metal parts. To this end, nichrome wire is coated with teflon.
Sourcing
- Teflon coated nichrome wire on Alibaba 200C - [1] - 36 cents/meter
- Pelican Wire makes coated resistance heating wire - [2]
- Fiberglass coated wire, 5' Ultimachine, 8 Ohm/foot ga 31, 290C max - [3]
- Take thin fiberglass sleeving and place nichrome inside,
- Fiberglass insulated - ebay - 200C limit - [4]; [5]
- Fiberglass insulated nichrome wire, only 150C max - [6]
- Fiberglass and other Sleeving for wire - [7]
DIY
- Coat it with chimney cement - [8]
- Use ceramic beads - [9]. Recyclebot work. Claims temperature can be higher than pre-coated wire. Suggests also https://pelicanwire.com/
