Alduti-Rupter® Switches

Construction Detail

Alduti-Rupter SwitchAlduti-Rupter Switch
  1. Stationary contact features thermally sprayed pure silver contact surface, coined for hardness, contour, and low porosity
  2. Spring-backed silver-nickel multifinger blade contacts provide four independent points of contact for optimum performance and contact pressure
  3. S&C Cypoxy® Insulator provides nontracking, self-scouring, nonweathering performance. Also available with porcelain station post insulators
  4. No-external-arc interrupter. Interrupter contacts and blade are synchronized to coordinate dynamic internal dielectric strength with interrupter’s external striking distance, eliminating any chance for flashover
  5. Double-member, hard-drawn copper blades are formed and trussed for extra rigidity. They’re permanently aligned for trouble-free switching
  6. Hinge contacts feature silver-nickel contact buttons brazed onto switch blades, plus a silver-clad hinge pivot. Stainless-steel loading spring is engineered to optimize contact pressure, operating ease, and blade stability
  7. Formed channel base — 3/16-inch galvanized steel. Numerous mounting holes suit any structure
  8. Corrosion-resistant bronze bearing in stainless-steel-sleeve provides smooth maintenance-free performance
  9. Articulated-drive operating mechanism accommodates wide selection of mounting arrangements
  10. Fault closing contacts feature copper-tungsten disks silver-brazed to copper blade-tongue, and carbon-block or copper-tungsten-block jaw
    Current-carrying contacts consist of four silver-nickel contact buttons brazed onto copper blade-tongue; and self-aligning, four-finger, spring-loaded, silver-clad copper jaw
  11. Low-inertia Cypoxy® operating rod permits high-speed operation. Operating rod is designed to withstand all dynamic tensile and compressive forces
  12. Rectangular-section, heavy gauge, galvanized steel base
