> I've always been curious how modern electric heating elements are assembled in a safe manner. I mean ones that use nichrome heating wire , inside a metal tube. The metal tube is packed with insulating material. Like how is the heating wire maintained in a position so it touches the smallish diameter metal pipe. Probably in a very similar way to mineral insulated cables, if not the exact same process: https://en.wikipedia.org/wiki/Mineral-insulated_copper-clad_cable https://en.wikipedia.org/wiki/Mineral-insulated_copper-clad_...
