MI Cable
Mineral insulated (MI) cable consists of one or two resistance heating elements embedded in highly compressed magnesium oxide covered by a copper or an Alloy 825 stainless steel sheath. Application requirements determine resistance size and sheath material.

Terminal Construction
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.

HDPE Jacketing
Extruded, high-density polyethylene jacketing can be specified to provide optimal mechanical and corrosion protection. HDPE jacketing safeguards against damage during installation or use. It also provides a superior defense against corrosive chemicals, such as calcium chloride, and salts.

CONSTANT WATT HEATING CABLE:
is specified for applications requiring a constant heat output regardless of fluctuating outside temperatures.

MINERAL INSULATED (MI) HEATING CABLE SYSTEMS
& ELECTRIC HEAT TRACING:
is specified when long life, design flexibility, non-combustion, defined heat output, and rugged construction are important.

SELF-REGULATING (SR) CABLE:
is specified for applications requiring heat put to vary with changes in temperature. SR cable increases heat output as temperature decreases, and conversely, decreases heat output as temperature increases.
