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.
From Google - about how manufactured ....An electric heating element inside a metal pipe is a common design for tubular heaters, which consists of a resistance wire (often Nichrome) coiled in the center of a metal tube. The space between the wire and the tube is packed with an electrical insulator, such as magnesium oxide powder, which conducts heat efficiently while preventing the wire from shorting against the pipe. This design allows for durable, efficient heating as the heat is conducted from the element to the pipe's outer surface....
