ADVANCING THE POWER GENERATION INDUSTRY
  Brush Changing Made Easy – The Fulmer Way
 

Fulmer has the safe, reliable and economic solution for brush changing on
live machines.

  Featuring a state-of-the-art design, the single pocket, cartridge-style plug-in holder (FC101) offers a revolutionary approach to brush changing on
turbine-generators. Using the same design concepts found in multi-pocket magazine holders that have been commonly fitted to larger generators for over 40 years, Fulmer has
successfully adapted this model into a unique single pocket holder.
  Coupling technical, design and manufacturing expertise with substantial experience working with OEMs in the power generation field, Fulmer has created a holder concept built around the principles of employee safety, superior technical performance and value.
  Product Features
Lightweight and ergonomic, Fulmer’s patented, OEM-approved design is a direct replacement for original brush holders with no rigging modification required.
  Fulmer’s holder offers constant force springs and insulated handles for quick and safe brush changing under load.
  Both brush and brush holder can be removed while the generator is on-line, without any service interruption.
  Utilization of a constant pressure “cartridge” design eliminates the need to periodically adjust brush force as the brush wears (saving valuable maintenance man-hours).
  The constant pressure spring is radially mounted over each brush, while the concentrically coiled spring applies force on the center line of the brush.
  Individual brushes can be changed on an “as-required” basis, safely away from the electrically energized components.
 
 
 
 
 
THE FULMER ADVANTAGE
  Fulmer’s Cartridge-Style Plug-In Brush Holder (FC101):  
  Eliminates the use of high resistance and mechanically inferior connection plates and contacts.
  Allows for superior electrical contact, improving current flow to the brush.
  Has a longer brush box, creating better brush support and accommodating brushes up to four inches in length.
  Lengthens brush life and reduces the frequency of brush changes.
  Utilizes any brush supplier’s recommended brush grade for high speed generator service.
  Facilitates brush wear evaluation though a convenient window in the brush holder.
  Offers handle versatility – the shorter handle’s flash guard keeps fingers away from brush shunts, while the extended handle (optional) can be used for holders that are difficult to access.
  Enables operators to quickly and easily change brushes once the holder has been removed from the generator using a portable brush load fixture.
  Utilizes standard brushes and terminals.
  Is economically priced.
  Improves machine performance by reducing brush selectivity and enhancing airflow and cooling.
  Eliminates the need to change springs when the brush is changed.
  Reduces the chance of a flashover.
  Accommodates both North American and internationally designed machines.
BRUSH HOLDERS THAT DELIVER RESULTS
  Several thousand of Fulmer’s cutting-edge brush holders are currently in use on newly commissioned OEM generators (both air and hydrogen cooled, ranging from 25 to 450 MW) and aftermarket conversions. Customers can attest that selectivity issues with the original OEM holders were drastically reduced upon the installation of Fulmer holders, and there have been dramatic improvements in operator ease and safety.
