Mineral Insulated Cables

Mineral insulated cable is made by placing copper rods inside a circular copper tube and filling the intervening spaces with dry magnesium oxide powder. The overall assembly is then pressed between rollers to reduce its diameter and increase its length. 

Mineral insulated cable is used in critical fire protection applications such as alarm circuits, fire pumps, and smoke control systems. 

Fused Magnesia (derived from fusing Caustic Calcined magnesia) or Deadburned Magnesia with low iron and other specific physicochemical properties make GM’s products perfectly suitable for this application.
