MI CABLE FOR HEATING Mineral insulated (MI) heating cable consists of one or two resistance heating elements embedded in highly compressed magnesium oxide covered by a copper or stainless steel sheath. Application requirements determine resistance size and sheath material.
Terminal Construction of Heat Cable : All 1 and 2 conductor cables come fully terminated and moisture proofed. The end termination consists of a thermal gradient section butt-connected to 19-strand THWN cold leads. The cold leads are crimped and soldered to the thermal gradient section, insulated with a high-dielectric, high-temperature tape, and epoxy potted in a rigid brass sleeve. The thermal gradient section is silver soldered to the heating wire and protected by a rigid brass sleeve with magnesium oxide.
