What is a mineral-insulated heating cable and why does it matter?

A mineral-insulated (MI) heating cable consists of a central metal conductor surrounded by a compressed mineral insulation — in Hott-Wire’s case, inert fiberglass — encased in a copper outer tube and coated with an HDPE jacket. MI cable technology was first patented in 1896 and has been used in critical applications including nuclear reactors, fire alarm systems, military equipment, and emergency infrastructure precisely because of its extraordinary durability and resistance to mechanical damage, high temperatures, and moisture. Heatizon’s Hott-Wire brings this industrial-grade construction to snow melting applications, engineered specifically for radiant heating performance.
