Crimping machine for composite insulator flange

What is crimping machine? Crimping machine is a kind of machine used to crimp the bottom flange of high voltage insulators in insulator production. With high pressure from hydraulic power force, crimping machine press the metallic flange from all direction and make the metal fittings (flange) well attach the core of composite insulators. Crimping machine is also […]
