  Tubular Finned: Construction

Construction
  1. Steel, stainless steel or incoloy sheathed elements.
  2. Element wire situated in proximity to outside surface for maximum heat transfer and minimum internal temperature while presserving good dielectric qualities.
  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.
  8. Painted steel or stainless steel continuous fin (approx. 5 per inch)
