Sample test is a major method of insulator acceptance inspection for mass production. It is widely used by inspectors of insulators from manufacturers, power girds and electrical laboratories. Here we have definition, rules, test method and acceptance criteria of composite insulator of suspension type and tension type of international standard IEC 61109:2008 “spension and tension […]
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 […]
Name：Mechanical failing load tester for insulator (Cantilever & Tension) Other name: Cantilever/Tension failing load tester for ceramic/polymeric/glass insulator Introduction: This Mechanical failing load tester is designed to do type test and sample test on high voltage electrical insulators, testing their mechanical performance of cantilever failing load and tensile failing load. It is also called bending testing machine sometimes for […]
Insulator Machine: Insulator tensile testing machine (Also known as insulator tensile tester/tensile machine/tension test machine/tension tester/pulling machine /insulator strain machine/tensile tester for high voltage electrical insualtor) What is “insulator tensile testing machine” (insulator tensile tester) Insulator tensile testing machine is designed to perform mechanical property tests (tensile tests) of various types of steel wires, cables, […]
