Electrical instrument transformer

The product range encompasses the full series of power transformers—ranging from 0.5 to 35 kV—including metering low-voltage current transformers, metering electromagnetic current transformers, metering electromagnetic voltage transformers, and metering combined transformers, as well as integrated primary‑secondary transformers and storage-type transformers, with over 200 model variants.

Miniature current transformer

Our product lineup includes miniature voltage transformers, miniature current transformers (used in smart meters, low-voltage electrical devices, arc-fault detection, smart terminals and instruments, etc.), split-core current transformers, Rogowski coil current sensors, fluxgate current sensors, residual current sensors, Hall‑effect and magnetoresistive current sensors, and a range of other related products.

Magnetic materials

Our product portfolio includes pressure‑ and gravity‑molded nanocrystalline strip‑wound cores, cores for miniature current transformers, cores for electromagnetic power transformers, cut‑type magnetic cores, as well as magnetic components such as common‑mode inductors and high‑frequency reactors. These products are primarily used in high‑voltage current transformers, residual‑current devices, high‑frequency transformers, inductors for inverters in new‑energy applications (solar and wind), transformers for other high‑frequency power supplies (electroplating, induction heating, and welding power sources), precision measurement transformers for instruments and meters, sensors, EMI‑suppression filter inductors, and amorphous‑core motors, among others.
