Insulator type tests are performed to evaluable the suitability of insulators for use in 10kv to 1000kv overhead wiring systems or electrical systems.

There are some Insulator type tests done in the laboratory
◆ In the certain circumstances, such as in 15kv voltage, changing one conditions, look and record the insulator applicable data and phenomenon
◆ Mechanical strength test
◆ Power frequency flashover voltage test
◆ Withstand voltage test
◆ Puncture voltage test
◆ Creepage distance test
◆ Pollution testing

Insulator type tests is tested in accordance with insulator specifications
◆ AS/NZS 2947 Insulators – Porcelain and glass for overhead power lines – Voltages greater than 1000 V a.c. Part 1: Test methods – Insulator units
◆ AS 4398 Insulators – Ceramic or glass – Station post for indoor and outdoor use – Voltages greater than 1000 V a.c. Part 2: Tests
◆ AS 4435 Insulators – Composite for overhead power lines – Voltages greater than 1000 V a.c.Part 1: Definitions, test methods and acceptance criteria for string insulator units

Insulator type tests can also inspect in accordance with ANSI C29.1 and IEC 60383 specifications for ensuring insulator quality and insulator performance.
