M.I. Permafrost Prevention Cable

Mineral insulated (M.I.) cable consists of one or two conductor heating elements embedded in highly compressed magnesium oxide covered by a copper or an Alloy 825 stainless steel sheath.

Each Delta-Therm M.I. Cable assembly is fully terminated and moisture proof. The end termination consists of a 3' (91cm) thermal gradient section connected to 20' (6m) 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 element and protected by a rigid brass sleeve.
