Composite insulator tests

Composite insulator tests will be shown in the following. Based on the purpose of testing, the tests to be performed on polymer insulators are classified in four categories.

Composite insulator Design Tests: Design tests are performed to verify the suitability of the manufacturer's design, materials, manufacturing process and technology. When an insulator is submitted to the design tests, the results shall be considered valid for all insulators of the same design that are represented by the tested one. The design tests are performed once.

Composite insulator Type Tests: Type tests verify the main characteristics of the insulators, which depend mainly on its shape and size. They shall be repeated when the design, type, or size of the insulators changes. Three production line insulators of the relevant type shall meet the requirements.

Composite insulator Sample Tests: Sample tests verify other characteristics of the insulator, including those which depend on the quality of the manufacture and on the material used. They are performed on insulators taken at random from a lot offered for acceptance.

Composite insulator Routine Tests: Routine tests are conducted to detect and discard insulators with manufacturing defects. They are made on every insulator produced.
