Mineral Insulated Heating Cable

As the world’s largest manufacture of Mineral Insulated Cables and experts on Trace Heating design, supervision and control; we pride ourselves on offering the widest possible range of Heating Units to suit your Trace Heating needs.

Mineral Insulated Cable is known as the most durable cable in the world. It is the ideal choice when an application's temperature and power output requirements exceed the capabilities of self-regulating and constant wattage cables. MI heating cable can be used for applications with the following requirements:

Advantages of Mineral Insulated Cables



  • Single and dual core series heating resistance cable, magnesium oxide mineral insulated, metal sheath
  • High strength
  • Heating resistance cable resistance (ohms/m) determines the power output per unit length.
  • Output power constant, independent of temperature variations.
  • Maximum working voltage up to 750V.
  • Output power up to 300W/m (typical max).
  • Highest maintain temperature up to 800 ℃.
  • Maximum exposure temperature up to 1000 ℃.
  • Hot and cold end fittings are usually prefabricated in the factory

As the world largest manufacturer with three manufacturing plants on three continents, we have the entire range of heating units to choose from so we can use our experience and expertise to design the most efficient system. This comprehensive range ensure a quick solution to any heating problem.

With this comes total traceability to ensure the highest quality solution. This is vital, as the composition of the cable must be able to withstand incredibly harsh conditions. MICC make all the connections and seals at the factory with advanced technology, which guarantee a consistently high level of quality. Specific ranges of MI heating cables and units are approved by various hazardous and corrosive area approvals.

Cable Configuration

An MI heating unit consists of the heating cable, the hot-cold joint and the cold lead cables with an appropriate seal and gland. The connecting and sealing of an MI heating unit is critical for safe and reliable operation, please refer the below pages for standard construction types.

The insulation of the inner heating conductor is embedded in magnesium oxide, a non-aging and non-combustible material. A wide range of resistances ensures the termination of a multitude of heating cable lengths with various outputs and nominal voltages. We offer both single core and dual core resistance wires as well as a seamless outer jacket made from Copper, Cupro-nickel, Stainless Steel, Inconel or Alloy 825.

MICC Mineral insulated (MI) series heating systems are particularly suitable for heating applications where high power output, high exposure temperatures, or extreme resistance to environmental corrosives is needed (Alloy 825).

MI heating systems provide the most reliable solutions for temperatures of up to 1000℃.

They are your reliable solution for frost protection, temperature maintenance and generation of process temperatures up to 700℃.

Mineral insulated heating cables are suitable for heating of pipes, vessels, flanges and valves and many other applications in both hazardous and non-hazardous area applications.
