Resins and coa­tings for medium and high-vol­tage applications

We have a wide range of pro­ducts for electri­cal insu­la­tion. These pro­ducts have been spe­ci­fi­cally deve­lo­ped to meet the most deman­ding con­di­ti­ons in medium and high vol­tage electri­cal insu­la­tion systems.

The sys­tem approach to insu­la­tion solu­ti­ons ensu­res that our resins are tailo­red to both the app­li­ca­tion and the indi­vi­dual down­stream pro­ces­sing, such as vacuum pres­sure imp­reg­na­tion (VPI).

Pro­ducts and solu­ti­ons

Von Roll and Dol­ph’s® resins are an essen­tial part of insu­la­tion sys­tems for all types of rota­ting machinery, motors, and gene­ra­tors. The choice of the right mate­rial depends on the final application.

Depen­ding on the app­li­ca­tion requi­re­ments, we offer our cus­to­mers resins with dif­fe­rent and opti­mi­zed che­mi­cal com­po­si­ti­ons from our Dam­i­sol® and Per­ma­fil® pro­duct families.

  • Sili­cone resins for high tem­pe­ra­ture app­li­ca­ti­ons, such as trac­tion machines
  • Epoxy resins for best electri­cal pro­per­ties and use in harsh environments
  • Polyester(imide) resins for best pene­tra­tion and cost-effec­tive curing com­bi­ned with excel­lent electri­cal properties

For addi­tio­nal pot­ting and pro­tec­tion of electri­cal com­pon­ents, we offer a wide range of pot­ting resins and pro­tec­tive coatings.

Our cus­to­mers trust our Dami­val® and Dami­coat® pro­duct ran­ges, which are espe­cially tailo­red to the requi­re­ments of medium and high vol­tage applications.
