magnesia insulated cable

Mineral insulate cable

Mineral insulated cable is also called fireproof cable or copper-conductor copper sheathed magnesia insulated cable in china,known as MI cable abroad. In 1985,swiss researched and developed this cable and received the patent. in 1934,this new technology was converted into the production for the first time in france. The emergence of MI cable demonstrates the innovation of tranditional cable,especially,its effect in the some importance areas and electric circuits,it leaves the plastic cable in the dust. Due to the particularity of product material and structure,it has high electric property,mechanical performance enviroment resistance and environment protection that the continuous promotion of this product,people require higher demands for safety,it is recognized by more and more people,and now it has been widely applied to the basic industry and civil construction.

Mi cableis composed of high-conductivity copper conductor,mineral(magnesium-oxide)insulator and seamless copper tube sheath,if the cable is used in the location where the copper will be eroded,it may be added with plastic sheath(optional) at the outermost layer.
