Design tests for composite post insulator
There are two kinds of post insulator: composite post insulator and porcelain post insulator. They are named according to the different materials. As the composite post insulator has more advantages, so the composite post insulator is replacing the porcelain post insulator. So the design tests for composite post insulator are becoming increasingly important. In this article, we will focus on the design tests for composite post insulator.
The design tests for composite post insulator:
The design tests for composite post insulator are performed only once and the results are recorded in a test report. Each part can be performed independently on new test specimens, where appropriate. The composite insulator of a particular design shall be qualified only when all insulators or test specimens pass the design tests.

Tests on interfaces and connections of end fittings:
Three insulators assembled on the production line shall be tested. The insulation length (metal to metal spacing) shall be not less than 800 mm. Both end fittings shall be the same as on standard production insulators. The end fittings shall be assembled so that the insulating part from the fitting to the closest shed shall be identical to that of the production line insulator. If spacers, joining rings or other features are used in the high voltage insulator design (notably for longer insulators), the sample shall include any such devices in a typical position.
Except the composite post insulator, we also produce HV porcelain station post insulator and ceramic station post insulator. As we are professional manufacturers, we have large quantities of knowledge about the insulators, and we also have the tests for HV porcelain station post insulator and ceramic station post insulator such as the sample tests for HV porcelain station post insulator and design tests for ceramic station post insulator.
