Insulator testing machines

Machines and devices to perform electrical tests and mechanical tests on electrical insulators,cables and fittings

What machines are needed for 11kV polymer insulator production line?

Polymer insulators are important electrical items in electrical power overhead transmission, distribution, and substation lines. They provide reliable insulation between cables and iron towers, or between conductors and connecting fittings like clamps so that the electricity can be transmitted safely. With the global growth of the electrical industry, more and more people smell the potential […]

Test of sheds and sheath material of composite insulator

Composite insulator’s shed and sheath are be made of high temperature vulcanizing (HTV) type silicone rubber, having silicone polymer content by weight 30% minimum. Alumina Trihydrate (ATH) is used as a filler. The filler is properly mixed with silicone compounds to ensure uniform distribution. The thickness of the sheath shall be a minimum of 3 […]

Content of IEC 61284:1997 Overhead lines – Requirements and tests for fittings

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 […]

Routine tests of composite insulator with voltage greater than 1000V in IEC 61109 2008

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 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 […]
