GRP/FRP Dogbone for Electric Motor Winding Support in Dry Type transformer

Short Description:

Made of fiber glass yarn (FRP/GRP) and resin, GBS FRP Epoxy Dog Bone is a specially shaped pultruded component and being used as a dovetail spacer in coil winding assembly in Dry Type transformers. Its hourglass design allows uniform stress distribution, making it ideal for tensile strength tests and other structural applications.

Dog bone can improve the efficiency and reliability of electric motors and reduce the maintenance cost.
