What is a Combined Electro-Mechanical Strength Test?
A combined electromechanical strength test is a significant test for electrical ceramic insulators of overhead lines. It is a necessary and basic type test for manufacturer and research institutes to inspect the quality of porcelain disc insulator, during which high voltage is applied to both ends of disc insulator ( ball & socket ) and at the same time the certain mechanical tensile load is applied to the insulator to simulate the online environment.
This combined electromechanical strength tester is designed to perform such test of insulators, it is made of two parts:
Mechanical part: universal testing machine to perform tensile/compression test
Electrical part: electrical power transformer to generate high voltage

Cantilever & torsion tester is called “Bending and torsion testing machine”. It’s used for mechanical bending and torsion test of post insulators. The test methods and acceptance criteria shall be subject to IEC standard 61109 and 60383. The cantilever test ( bending test ) are commonly seen in manufacturer of composite insulators, the insulators under this test are for the purpose of overhead power transmission lines, while the torsion test is for power station post type insulators.
This testing machine is designed to perform mechanical property tests of long rod insulators, steel wires, cables, conductors, power fittings,chains, electrical devices, it's also available for mechanical property tensile tests on other specimen with long shape.
