Damage limit proof test and test of the tightness of the interface between end fittings and insulator housing in IEC61109:2008

Damage limit proof test and test of the tightness of the interface between end fittings and insulator housing,these two tests are two of the most important test in inspection process of composite insulator. Here is how international standard IEC 61109:2008 “Suspension and tension insulators for AC system with a nominal voltage greater than 1000V” defines these 2 […]

Insulators tested in vertical position and horizontal position

As we know,high voltage insulators shall subject to mechanical failing load test, and when we mention “test in vertical position and horizontal position”, this more refer to suspension insulator, tension insulator, post insulator and pin insulator. The suspension and tension insulator are normally tested in horizontal direction, as they are long in shape, with length […]

End fitting of railway insulator of Indian market

End fitting of railway insulator of Indian market The end fittings of silicone composite insulator for 25KV railway overhead traction have specific requirements. The end fittings shall be made of spheroidal graphite cast iron to grade: 400/15 of IS:1865-1991 or forged steel fittings to BS-970(Part-II). Approval of the type test of the insulator implies employment […]
