The mineral insulated cable comprises the cooper conductor, magnesium oxide imsulator, a copper sheath. If necessary, there is outer plastic jacket outside copper sheath. It can be provided with an Halogen-free, low-smoke sheath in necessary occasions.

As Mineral insulated cable (fireproof cable ) is made of inorganic materials, therefore it has some characteristics superior to any other cables, such as fire proof, high current rating, high strengh, halogen-free and no toxicity, esposion proof, water proof, corrosion resistance, long service life, high overload, high operating temperature, low cost and small curve radius.
