Magnesium oxide insulation of specific grain and purity, swaged to the proper density, results in high dielectric strength and contributes to faster heat-up.
AWatt densities to 400 Win2 (62 W/cm2)
Incoloy® sheath resists oxidation and corrosion from many chemicals, heat and atmospheres
Nickel-chromium resistance wire, precisely wound and centered in the unit, assures even efficient distribution of heat to the sheath.
