How To Make Mineral Insulated Cable?

Mineral insulated cable production process and equipment and needed more professional. Let us introduce three ways of mineral insulated cable production processes.

The first process is also the earliest and most commonly used porcelain column assembly method. Most of the production and manufacturing mineral insulated cable manufacturers are currently using this process.

It uses sintered magnesium oxide porcelain column hand-filled to the copper tube and copper rod between and after a series of drawing annealing the final product. The biggest drawback of this cable production and manufacturing process is the labour intensity and low production efficiency.

The second process is called the magnesium oxide powder filling method. The standard image analogy is like a funnel between the vertical copper rod and the copper tube filled with magnesium oxide powder. This processing can make the conductor and sheath concentricity better, but this production equipment is almost rare. In the filling process, magnesium oxide powder may be damp. The production workshop requires to be sealed and dry. The air humidity requirements are more strict.

The third production process is the world’s most advanced copper belt longitudinal welding method. This mineral insulated cable production process principle is that the copper belt and copper rod can be infinitely welded and let the copper belt longitudinal welding moulding wrapped around the copper rod. In the copper rod and welding between the copper belt filled with magnesium oxide powder. The main production equipment of mineral insulated cable is a wire drawing machine, extruder, cable machine, braiding machine, fork twisting machine, inverted wire machine, wire measuring machine, bundling machine, etc.

There is also the introduction of advanced magnesium oxide powder infusion equipment, processing mineral insulation layer equipment, longitudinal copper sheathing equipment, etc. According to the process of choosing different equipment. There are also these special cables for the working environment requirements are even relatively high.
