Toroidal Core

toroidal_core core
We make toroidal cores by using nickel permalloy for Current Transformers, Coverters and Inverters.
The toroidal cores is for making Current Transformers, Converters, Inverters and Digital watt meter.
Vision Technologies sets a goal of producing the best quality cores based on customized size and raw materials.
We have ourselves technology of Inlac(Methyl Methoxid) Coating.
When wound into a toroid, this Inlac coating physically separates the laminations and reduces the possibility of interlamination welding. It also helps prevent shot spots and wicking in the core, to ensure the material is consistently annealed.
