Testing Machines of Insulators
Electrical test machines and mechanical test machines for high voltage overhead transmission line insulators.
Insulator Testing Machine of Thermal-Mechanical Stress
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.
Combined Electro-Mechanical Strength Tester of 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.
Zinc thickness test device
Zinc thickness test device is a portable test equipment for zinc coating thickness of metallic fitting of high voltage insulators.
Water diffusion test device for FRP core
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.
Tracking & Erosion Test Machine of Polymer 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.
Porosity Testing machine of Ceramic Insulators
