Slot Wedge

In the core structure of electrical equipment such as motors and generators, slot wedges serve as an indispensable key component. Primarily installed at the slot openings of the stator or rotor core, they play a critical role in fixing, insulating, and protecting the windings embedded in the slots. This directly impacts the operational stability, efficiency, and overall service life of your equipment.

Custom Solutions With years of experience in new material research and development, RDS is committed to being an expert in this field. We provide a comprehensive series of slot wedges tailored to meet the specific needs of our customers.

Manufacturing Processes Our advanced manufacturing capabilities for slot wedges include:

  • Precision Machining: We expertly machine laminates into custom slot wedges according to your specific drawings. Available laminate materials include G10, FR, G11, FR5, EPGC308, and magnetic conductive laminates.

  • Pultrusion: We can create uniquely shaped profiles tailored to specific slot wedge designs. These are typically manufactured from epoxy or polyester resin reinforced by high-quality fiberglass, offering a thermal grade ranging from B to H.
