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...
Pressure Relief devices/valves are typically classified in the Transformer industry as safety or protection devices transformer pressure relief device valve for liquid-immersed transformers open in...
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...
When the transformer is in operation, heat is generated due to copper losses in the windings and iron losses in the core. The removal of heat from the transformer is known as cooling of the transfo...
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 ...
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...
