1 100 kV hollow porcelain insulator for capacitance bushing is a key device in 1 100 kV capacitance bushing.According to technical requirements of the 1 100 kV capacitance bushing to hollow porcelain insulator

the design

manufacture and test of 1 100 kV hollow porcelain insulator was introduced.Establishment of craft data for designing mouthpiece extension of vacuum pug mill used for extrusion

and the cause and measure of the large-diameter clay body breaking and cracking during extruding were focused on.Turning technology requirement was satisfied after reforming the inner bore knife rest

and the problem of the clay body crazing during drying and firing was solved after increasing constant rate drying time and re-drying after glazing.The problem that great base sinking and cracking was solved effectively by cutting repeated and slowing entering speed.The phenomena that interface pressure puncture of organic adhesion porcelain was analyzed

and the effective measure was proposed.The test results showed that the products passed all the experiments that required.
