mineral insulated wire,
mineral insulated heating cable
Single Copper Core Mineral Insulated Cable for Industrial Heat Tracing, is a kind of mineral insulated cable with one single core conductor inside. It is widely used on industrial heat tracing to make the pipeline, flange, tank, facilities at a certain temperature range.
Mineral Insulated Cable (short as MI Cable), it is also called magnesium oxide Cable or fire-resistant Cable as the wiring application.
Mineral insulated cable possesses a long history of more than one hundred years. It has been developed and put into production in major industrial countries, such as Italy, Canada, Australia, the United States, Russia, Japan etc. China started development and production in the 1960s, began mass production at the end of the 20th century, and put into the national fire design specifications on a large number of domestic applications since the beginning of this century.
Composition of Mineral insulated cable
Mineral insulated cable is a kind of cable which USES annealed copper as conductor, dense magnesium oxide as insulation and annealed copper pipe as sheath. If necessary, it can be squeezed with a layer of plastic outer sheath around the annealed copper sheath. For specially required occasions, a layer of low-smoke halogen free sheath can be applied.
Advantages of Mineral Insulated Cables
Since all the materials of this cable are inorganic, it has some advantages that other cables cannot have, such as, fire prevention, high current carrying capacity, resistance to mechanical damage, non-toxic, non-halogen, explosion-proof, waterproof, corrosion resistance, long life, safety, overload resistance, high temperature resistance, low cost, small bending radius, anti-ant, anti-rat bite, copper sheath used as a protective grounding wire and so on.
