The cutaway view shows the tubular heater’s basic construction.
A computer-designed helical coil of 80% Nickel 20% Chromium alloy resistance wire is fusion welded to the nickel-coated steel terminal cold pin.
This coil assembly is precisely stretched and centered in the element metal sheath
The sheath is then filled with Grade “A” Magnesium Oxide powder (MgO).
The filled tube is then compacted by a roll reduction mill into a solid mass, permanently stabilizing the coil in the center of the tube while providing excellent heat transfer and dielectric strength between the coil and the sheath.
