Mineral Insulated Heating Cables are the most rugged heating cable. Constructed of a solid series resistor element embedded in highly compacted mineral insulation, MI cables are built to handle high temperature, high wattage applications. Mineral insulated cables are factory assembled and tested, ensuring the highest quality product. Since the units consist of a series resistor, virtually any wattage/voltage/length cable configuration can be produced within the cable's physical operating limits. Our Mineral Insulated cables are available for use up to 600V and are tested and approved for use in corrosive and hazardous areas.
