Current Transformer Nanocrystalline Cores
The properties of nanocrystalline alloys present a unique combination of low losses and high permeability achieved by NiFe alloys and cobalt amorphous alloys, but with a saturation much higher than either of these materials can offer.
Nanocrystalline cores offer better performance than NiFe cores, both in permeability throughout the B/H curve and also higher saturation induction. With respect to silicon steels the saturation is lower but due to the chemistry and thickness, of the ribbon, the power loss is also much better.
Core packaging
Core packaging can be plastic case , metal case, insulation taped or epoxy coating.
Stainless steel and Aluminum materials are available for metal case.
PBT, PA66 and DMC materials are available for plastic case.
Nanocrystalline Split cores also available to meet the increasing demands of easy assembly Split Transformers.
Other shape cores such as Rectangular cores and Stadium Cores can be customized to your requirements.
Applications
Current transformers with 0.2, 0.2s, 0.1 accuracy class. Bushing current transformer for gas insulated or oil-immersed switchgear . Lv, Mv & Hv switchgear, and other apparatus in electric power transmission.
