Insulator porosity testing machine is applied to test porosity property of HV porcelain insulator under constant high pressure environment.

General Details

The porosity tester is to test porosity property of porcelain insulator. This tester is designed to inspect if there is gap,bulb or crack inside ceramic material, which is an important index of quality of ceramic insulator. As per required in IEC standard, such porosity test is necessary. Porcelain insualtor are broken into pieces and put into testing chamber during the test process.

Standard applied:
GB/T 775.1-2006 Test method of insulator
Equivalent to IEC 60383-1
Insulators for overhead lines with nominal voltage above 1000 V; part 1: ceramic or glass insulator units for A.C. systems; definitions, test methods and acceptance criteria

Available for porosity test of:

  • Ceramic post insulator
  • Ceramic pin insulator
  • Ceramic disc insulator
