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...
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...
Bus bars are an important component in the manufacture of transformers. They are a solid element that allows a flexible way of transmitting and distributing power. Busbars are produced in a variety...
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...
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 ...
A series of problems, such as larger diameter, the formation of waves on the cylinder, the deviation of the verticality of the assembly, and the unqualified performance after annealing during proce...
