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...
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...
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...
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...
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...
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...
