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...
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...
Trihope has successfully install and commissioned two paper-wrapped insulated wire auto wrapping machines in one of the largest cable factories in Mexico.
Paper wrapped round & rectangular wire...
In the working process of transformer, a lot of heat will be produced, which seriously affects the performance of transformer. During the operation of transformer, the loss of winding and core wil...
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 ...
Distribution transformers normally have ratings less than 200 kVA,[2] although some national standards can allow for units up to 5000 kVA to be described as distribution transformers. Since distrib...
