TESTING MACHINE OF INSULATORS
Electrical test machines and mechanical test machines for high voltage overhead transmission line insulators.
Test equipment for electrical tests pm overhead line insulators. This test machine tests high voltage insulators with power voltage and frequency. The power frequency tests are required in IEC, ANSI or any other technical standards for insulators of OHTL.
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.
Tracking & Erosion tester is used for tests of silicon rubber shed and housing of electrical polymeric insulators. It is to test the anti-tracking and erosion ability of its silicon rubber material as per IEC or DIN EN standard.
This equipment is applied to mechanical tensile and bending (cantilever) tests of insulators below 36KV with section length less than 1m. It's an economic test solution for the manufacturer of 11/33kV insulators.
A combined electromechanical strength test is a significant test for electrical ceramic disc insulators of overhead lines. This testing machine is essential for the manufacture of porcelain insulators to inspect and control quality.
Insulator polymer tightness tester is used to check tightness of polymer housing of composite insulator, whether the polymeric housing is well attached to FRP will be shown after 96 hours of boiling in salty water. This boiling process is also essential as preparation stage of some electrical test of composite insulator.
The water diffusion test device is to test the leakage current and withstand property of the FRP/ECR core of composite insulators under AC voltage after boiling in salty water. This test is defined and required in the IEC standard for tests of composite insulators.
The thermal-mechanical stress test is a sample test for composite insulators and porcelain insulators required in IEC. It tests insulators with the cycling of high temperatures and low-temperature environments.
The insulator porosity test machine is to inspect the porosity property of the HV porcelain insulator under a constant high-pressure environment with dye penetration.
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.
