Type SX-Sheath temperature 1200 degree F and 1500 degree F. Designed for heavy duty, high temperature applications. New size, 5/8" wide, lends a flexibility to its use not applicable to conventional 1-1/2" strips. Flat surface gives better heat transfer than tubular units and its one-end termination provides simplicity of wiring. CONSTRUCTION: Coiled nickel-chromium elements, precisely located within stainless steel tubular sheath, insulated with magnesium oxide, are flattened under hydraulic pressure to form a rigid flat heater bar. Terminals are fully insulated and enclosed in porcelain blocks. Clamps are available for mounting. Specify voltage when ordering.
