Porosity Testing machine of Ceramic Insulators

The insulator porosity test machine is to inspect the porosity property of the HV porcelain insulator under a constant high-pressure environment with dye penetration.

General Details

What is a porosity testing machine?

The porosity tester is to test the porosity property of the porcelain insulator. This tester is designed to inspect if there is a gap, bulb or crack inside ceramic material, which is an important index of quality of ceramic insulator.

How is the porosity test done to a porcelain insulator?

As required in the IEC standard, such a porosity test is necessary. Porcelain insulators are broken into pieces and put into the testing chamber during the test process.

Why the porosity test is also called the dye penetration test?

Because in the test, we use the magenta solution to add water or alcohol to make magenta dye penetrate into the ceramic pores, which is a dyeing process. Therefore, the porosity test is also called the magenta penetration test.

What IEC standard do we follow exactly for the porosity test?

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

What types of ceramic insulators are available for the porosity test?

Available for porosity test of:
Ceramic post insulator
Ceramic pin insulator
Ceramic disc insulator

What is the highest pressure of porosity testing equipment for insulators? How much MPa should I use for test?

The maximum pressure for testing is 35MPa, some customized type can reach 40MPa, but the recommended running pressure is around 15-20MPa for the good of lifespan and maintenance. Long time of peak pressure will largely consume the life span of inner parts, just like you cannot run a car at 200KM/hour all day long 24 x 7.

How can I get this porosity test machine? Is there local distributor?

We can send this equipment via ocean transportation to your nearest seaport in containers from China. Currently the cheaper way to get this is from us, the original manufacturer in China. We are also open to recruit distributors in your place if you are interested to be one.
