Molded Slot Wedge

Model	Product Name	Thermal Class	Features and Applications
YD3955	Heat-resistant Epoxy Magnetic Slot Wedge	H	Made from heat-resistant epoxy resin binder, high magnetic conductivity material and electrical glass fiber reinforcement via specific process. Uniform structure with good integrity, high hot mechanical strength (flexural strength >200 MPa at 155°C, elastic modulus 13000 MPa), excellent magnetic permeability and insulation resistance. Improves motor efficiency and reduces operating noise. Used for various generator stator/rotor and large power motors.
YD3965	High-temperature Magnetic Slot Wedge	C	Made from high-temperature thermosetting resin binder, high magnetic conductivity material and electrical glass fiber reinforcement via specific process. Excellent heat stability and mechanical strength, high magnetic permeability, good insulation resistance. Improves motor efficiency. Suitable for rail transit traction motors and other special motors.
YD3968	Polyimide High-temperature Slot Wedge	C	Made from polyimide resin and modified glass fiber cloth via special process. Excellent hot mechanical strength (flexural strength >270 MPa at 200°C) and heat aging resistance. Suitable for rail transit high-power traction motors or other high-temperature-rise motors and transformer coil fixation.
