Porcelain insulator identification includes many aspects, may include pre-manufactured or during the using process, such as ageing resistance.

pin insulator tests

Pre-manufactured porcelain insulator, porcelain insulator identification should include
◆ Insulator materials inspection, this ensure the insulator quality
◆ Insulator certificate, ensure porcelain insulator for sale, attract the insulator buyer
◆ Insulator manufacturers should be certified by countries

In the porcelain insulator manufacturing process, porcelain insulator identification should include
◆ Insulator tests
◆ The tests reports

In the using process, porcelain insulator identification should include
◆ Insulator properties inspection
◆ Environment inspection
◆ Service life inspection
◆ Ageing resistance inspection
◆ Voltage inspection

Porcelain insulator identification may be inspected in transpiring process, such as the porcelain insulator is not easily broken.
