Transformer Tips: Adding value to cork

Cork isn’t just for wine bottles — in transformer manufacturing, it’s becoming a critical performance material. By blending cork with specific rubber typologies, manufacturers are creating composite gaskets that deliver the best of both worlds: the sealing compatibility of rubber combined with cork’s superior compressibility, vibration damping, and sustainability profile. This quick tip breaks down how cork-rubber composites reduce transformer noise, minimize gasket extrusion, and bring a green advantage to power systems sealing solutions.
