VPI Vacuum Pressure Soaking Facilities is the important technological facilities in producing high-tension motors,transformers,tramsformers,electrical power condenser-s,high-tension paper-nsulation cables and other dactrical equipments and appliances After being Reated with the VPI techmology,it?s good in insulation,raises its effici-ency,adds the machinery strength,and solve the looseing while operation,It can prevent the short circuit and other insulationg breakdown.It raises the ability of damppro of and lengther the usage life.The vacuity is 65~200 Pa and the designed pressure is 0.3~1.6-Mpa.The inside diametre is 0.5-4m,and it can also be made as the users need.
