Transformer winding machine is the most important core production equipment in the production process of transformer. Its winding performance determines the electrical characteristics of transforme...
Foil coil is mainly used for small and medium-sized transformers with capacity less than 2000KVA. The advantages of foil coil are: good mechanical strength, not easy to deformation, can withstand s...
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 ...
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...
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...
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...
