Fiberglass Wedges and Profiles High Strength Insulation Solutions

Fiberglass Wedges and Profiles are precision-engineered electrical insulation materials designed for use in motors, generators, transformers, and high-voltage equipment. Manufactured from premium-quality fiberglass reinforced with epoxy or polyester resin, these wedges and profiles offer exceptional mechanical strength, thermal stability, and dielectric properties.

Available in various shapes such as wedges, rods, angles, channels, and custom profiles, they are widely used for slot insulation, phase separation, coil support, and structural reinforcement in electrical applications. Their high resistance to heat, moisture, and chemicals makes them suitable for demanding industrial environments.

At Harnawa Insulations., we provide fiberglass wedges and profiles in multiple sizes, thicknesses, and designs to meet customer-specific requirements. Our products comply with international insulation standards and are trusted by motor and transformer manufacturers across India and overseas.
