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.


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.

2.20 years experiences in magnetic cores manufacturing and exporting.


We are a group company located in Foshan, China, with two manufacturing plants, coving a production area more than 70,000Sqare meters. We specialized in a broad range of tape wound cores in Amorphous metal materials, Nanocrystalline alloys, Silicon electrical steels, and Mu metal Nickel alloys, for a wide variety of applications including solar inverters, new energy vehicles, instrument transformers, current sensors, common mode chokes, custom power transformers. We also manufacture high-performance components using our high-quality cores made in-house. One of the key factors to the success of TRANSMART is focusing on basic raw materials research and development. Our ability to tailor the composition and specific heat treatments according to our know-how enables us to design alloys with unique properties for specific customer needs. Transmart is one of the few companies worldwide that have mastered the rapid solidification process where alloys are being produced as a thin strip to its final thickness of typically 16 to 30 μm, for applications in photovoltaic inverter, medium frequency transformer, common mode chokes. Our factories are certified to ISO9001, ISO14001, IATF16949.
