Abstract

PURPOSE: To improve the insulation of a sheathed heater, by baking an insulating layer and hollow form in a metal pepe, filling the hollow with insulating material powder after being inserted with a heating wire equipped with terminals, and then throttling the pipe.
CONSTITUTION: Insulating material powder such as magnesia powder is mixed with a binder such as fluidized paraffin to make it pasty. This pasty mixture is extruded in a metal pipe 1 to make a form 5 having an insulating layer 2 and a hollow C. A heating wire 4 equipped with terminals 3 is inserted in the hollow C and the clearance around the wire 4 is filled with insulating powder 2' such as magnesia powder. The pipe 1 is then throttled to improve the density of the insulating layer 2 and the insulating powder 2' for ensuring the higher insulation
