Armored Heating Cable

Armored heating cables are industrial heating devices composed of a metal sheath, inorganic insulation layer, and heating wire, primarily used in high-temperature and corrosive environments. Their structural features include a seamless metal sheath, dense inorganic insulation layer (such as magnesium oxide), and characteristics like pressure resistance (1500VAC/1min), shock resistance, and explosion-proofing. ?
