Product Introduction

Mineral insulated heating cable is composed of a metal conductor (heating element), a tightly wound magnesium oxide insulation layer around the conductor, and a metal sheath (such as stainless steel, 825 alloy, or copper, copper-nickel) that has been drawn multiple times. If necessary, an additional corrosion-resistant outer sheath made of fluoropolymer (such as PTFE) can be extruded over the metal sheath.

MI heating cables are suitable for frost protection, insulation, and heating of process media in industrial or construction applications. They are especially ideal for pipelines that require high output power or need to withstand high-temperature steam purging. In environments that demand corrosion resistance and explosion-proof features, MI mineral insulated heating cables demonstrate excellent performance.
