The wires in each group are insulated from each other and are often twisted around a central core, and the whole is wrapped with a highly insulating covering layer. The mineral insulated cable, abbreviated as MI cable, is commonly called magnesia cable or fireproof cable in China when used as wiring; it is a copper core copper sheathed cable insulated with the mineral material magnesia powder, and the mineral insulated cable is composed of two inorganic materials, namely copper conductor, magnesia and copper sheath.

Then, the pressure pump is started to increase the pressure inside the sealed bin, and the material is evenly discharged into the extrusion die head through the discharge pipe and mixed with the core passing through the extrusion die head. Then, the cable passes through the two through holes, and the water is pressurized and injected into the annular water pipe and the connecting pipe by the operation of the water pump.
