G10 / G11 Epoxy Glass Slot Wedges

G10 and G11 epoxy glass slot wedges are rigid electrical insulation components used in electric motor rewinding, stator slot insulation and high-performance coil retention applications. Manufactured from glass reinforced epoxy laminate, these wedges provide excellent mechanical strength, dimensional stability and dielectric performance in demanding industrial environments.

These rigid epoxy fibreglass wedges are commonly used where higher mechanical strength and improved thermal performance are required compared to traditional wooden slot sticks. They are suitable for electric motors, generators, alternators and other rotating electrical equipment operating in demanding service conditions.

Typical FR4 / G11 epoxy laminate properties include high dielectric strength, strong compressive performance and excellent insulation resistance for demanding electrical applications. 

If you are matching an existing wedge profile, please provide dimensions, drawings or sample wedges where possible. This helps ensure the correct slot wedge profile and laminate grade are selected for your application.
