Power plant brush holder systems

Increased safety and reliability and decreased maintenance costs make the EASYchange brush holder system the first choice for some of the largest power companies in the US. Its insulated, ergonomic handle allows simple, online "rack in – rack out" removal and replacement of the brush and holder as a unit.

The design of the EASYchange brush holder system protects the brush-to-ring connection and combats carbon deposit build-up, brush binding, spring failure, poor terminal connections and photographing (imaging, ghosting or footprinting) on the ring. There are over 5,000 EASYchange holders currently operating with no holder failures for our customers. It is, quite simply, the best brush holder in the industry.

Online collector ring truing service

Cutsforth’s power service technicians specialize in safely restoring collector rings by performing our online truing (grinding) service. We have performed online collector ring truing on hundreds of units worldwide.

The range of collector ring problems we can solve includes increased brush vibrations, grooving and photographing. Experience the increased accuracy of our process over traditional "turning gear" methods, accomplished at operating speed and temperature.

Spiral groove re-grooving

Cutsforth performs spiral groove re-grooving, an offline process that restores the spiral (or helical) groove, which increases the life of your collector ring and saves you thousands of dollars in replacement costs.

Cutsforth provides collector ring manufacturing for turbine generators and large DC motors. We combine our years of on-site collector ring services with extensive manufacturing experience to produce a top quality product and installation experience.
