GWR Damping Resistor

㈠Description：

    Wirewound  Power  Resistors  feature  corrosion  resistant wire, helically   wound into a long spring-like coil.

  The coil  is then wound onto a spirally grooved, solid porcelain core,where each end of   the wire is fitted to a

  terminal, which clamps to the end of the core.Terminals, clamps, and all  related  hardware  are  made from heavy 

  stainless steel. The resistors  are  typically  mounted  between  "L"  brackets, using a‘  throughbolt’.Multiple

  mounting racks  are often furnished. This  construction  can be supplied open or with   enclosures for   personnel

  protection, or louvered enclosures for both personnel and all weather protection.

㈡Features：

   GWR Series  terminals are  formed at a 90 angle to allow the use of flat  bus-connectors. This eliminatesthe  need

  for cumbersome jumper  wires when  interconnecting resistors. The open ‘double helix’design   permits considerably

  more wire to be wound around the  porcelain core. The  electrically efficient construction of the GWR element allows

  the highest possible wattage ratings per linear inch,consistent with  NEMA standards performance.As an added benefit,

  the same design feature that permits the  high wattage  ratings,  (so much  more of the wire  surface is  exposed to

  the air), makes the GWR Series  Resistors an excellent  space heater, both for natural convection and  forced air use.

  Post Glover's GWR resistors are available UL Recognized and CSA Certified.
㈢Applications：
  The design and construction of the GWR Series Resistors makes them ideal for:

   Small horsepower crane control
   Wye Delta Starting
   Various other starting and speed regulating uses
   High resistance neutral grounding
   Heaters and Load Banks

   Elevator Controls
