IEC 60273 Indoor and Outdoor post insulators cantilever, tension, torsion test machine 

IEC 60273 Characteristics of Indoor and Outdoor Post Insulators for Systems with Nominal Voltages Greater Than 1000V

This standard applies to post insulators and post insulator units of ceramic material or glass intended for indoor or outdoor service, and to post insulators of organic material intended for indoor service in electrical installations or equipment operating on alternating current systems with a nominal voltage greater than 1 000 V and a frequency not greater than 100 Hz. It may also be regarded as a provisional standard for insulators for use on direct current systems.

The IEC 60273 standard specifies various tests, mainly including electrical performance tests, mechanical performance tests, environmental adaptability tests, and appearance and dimensional inspections. The specific content is as follows:

Electrical performance test:

Insulation resistance test: Measure the insulation resistance of the pillar insulator to ensure its good insulation performance.

Voltage endurance test: Verify the voltage endurance of insulators under specified voltage.

Leakage current test: measure the leakage current of insulators at a specific voltage and evaluate their insulation quality.

Mechanical performance test:

Tensile strength test: Verify the tensile strength of the insulator to ensure that it will not break under mechanical stress.

Bending performance test: Evaluate the performance of insulators under bending conditions to ensure their structural integrity.

Impact performance test: Verify the tolerance of insulators under impact.

Environmental adaptability test:

Temperature adaptability test: Verify the performance stability of insulators at different temperatures.

Humidity adaptability test: Evaluate the performance of insulators in high humidity environments.

Salt spray test: Simulate a salt spray environment to evaluate the corrosion resistance of insulators.

UV irradiation test: Verify the performance of insulators under UV irradiation to ensure their weather resistance.
