KUVAG designs and manufactures tubes for the high-voltage industry by processing pre-impregnated fibers or impregnating glass fibers in filament winding technology. Winding angles of fibers and layer structure of our tubes are varied to achieve desired features like resistance to high pressure or high bending strength. We have hundreds of mandrels with diameters up to 2.500 mm available. Machining with narrow tolerances and surface treatments of the tubes often completes our offer— manufacturers of transformers and high-voltage testing equipment value the outstanding quality of our products.
