According to the traditional manufacturing method of high voltage shunt capacitor shell

the bending mechanism is improved and open type portal structure with roll-over stand is designed.The proof calculation is made in accordance with the process requirement of high power capacitor shell and structure of new type numerical control bending machine for capacitor shell is designed by specific parameters.The prototype designed and produced is with high bending accuracy and reliable operation.Successive multi-side bending with such machine can be made and automation of all bending process is achieved.
