The thermal-mechanical test is one of the most significant tests for composite insulators. Here we have a partial section of International Standard IEC 61109 2008: Insulators for overhead lines – Composite suspension and tension insulators for a.c. systems with a nominal voltage greater than 1 000 V – Definitions, test methods, and acceptance criteria. IEC […]
Early since January 2020, the new type of coronavirus has shown up in China and it is now spreading to a wider range. Without strict control and official recommendation of “stay at home” to the mass majority of people, this coronavirus may have affected more people can cause a bigger loss. Now China government has […]
International standard IEC 61284:1997 “Overhead lines – Requirements and tests for fittings” has defined requirements and test methods of electrical fittings (line hardware) for overhead lines. The complete IEC standard includes English and French language version, it’s too long and a little difficult for quick explore. Here we quote the content of IEC 61284 for […]
Last time we talked about sample test of silicone composite insulator for AC system above 1KV, the IEC 61109:2008 has defined it clearly. Today let’s the coming section”routine test” of polymeric insulator in this IEC 61109: 13 Routine tests 13.1 Mechanical routine test Every insulator shall withstand, at ambient temperature, a tensile load at RTL […]
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 […]
After end fittings of HV insulators have been crimped onto the core by crimping machine, the entire electrical insulators are supposed to be able to bear certain specific mechanical load as they will be used on overhead lines to support conductors and other line fittings. Here let’s see how international standard IEC 61109 defines such […]
