As know oil-type transformers are the most common form of transformers. When an oil-immersed transformer is in use, the heat generated by the coil and iron core is first transferred to the insulati...
In Jul 2023, TRIHOPE has successfully installed and commissioned numbers of special transformer manufacturing equipment to its Mexico partners, including Foil Winding Machine, High voltage coil aut...
The year of 2022 was exceptionally difficult, especially for export-oriented enterprises. The epidemic of COVID-19 still has no end in sight, the cost of raw materials keeps rising, and sea freight...
I.Cause of Partial Discharge
The transformer insulator, metal body and so on are often with some sharp angle and burr, so the electric charges under the action of electric field intensity will conc...
The thermal stability of the insulation material is the main factor affecting the life and overload capacity of the oil-immersed transformer. By explaining the preparation process, physical and che...
effect of temperature on high pressure test
The change of temperature will fully affect the insulation resistance, so when the external temperature continues to rise, the movement of molecules and ...
