供管状加热器 石英电热管

features：
•the hotwatt tubular heater has built-in resistance to shock， vibration， corrosion and temperature extremes. the heater is swaged， reducing the diameter of the metal sheath and compacting the insulation. this insures rapid heat transfer and holds the coil in position for forming.
•many formations are available.
•long， trouble free service.
construction：
1.steel， stainless steel， copper， or incoloy sheathed elements.
2.element wire situated in proximity to outside surface for maximum heat transfer and minimum internal temperature while preserving good dielectric
3.pure magnesium oxide compressed to an optimum density for best heat transfer and electrical insulation at elevated temperatures.
4.weld connection.
5.cold pin.
6.insulator.
7.standard post terminal.
