Transformer
A transformer is a device that converts voltage, current and impedance based on the principle of electromagnetic mutual induction.
Its main components include the primary coil, secondary coil and iron core (magnetic core).
Key functions involve voltage conversion, current conversion, impedance conversion, electrical isolation and voltage stabilization (for magnetic saturation transformers).
Our company mainly manufactures dry-type distribution transformers, which are widely used for voltage and current conversion in rail vehicles, energy storage cabinets and converter cabinets of new energy vehicles.

features
Insulation heat resistance
H-class insulating materials are adopted, which improves insulation reliability and heat resistance, and can effectively extend the service life of the product.
High dielectric strength
Adopting the VIP (Vacuum Pressure Impregnation) process suppresses transformer noise and improves dielectric strength.

01
Support for high-performance mass production
Relying on fully automatic winding, vacuum impregnation and precision assembly production lines, we realize large-scale and consistent production of high-frequency, high-power transformers (suitable for photovoltaic inverters, energy storage converters, on-board chargers for electric vehicles and other applications).
We support rapid switching of multi-specification magnetic cores and complex winding structures to meet customers' diverse electrical performance and packaging size requirements.

02
Customized electromagnetic and thermal design services
Our experienced R&D team provides complete electromagnetic design and simulation optimization — including loss, temperature rise, leakage inductance, and EMI performance — tailored to customers’ specific topologies (such as LLC, DAB), power ratings, operating frequencies, and efficiency targets.
We also support application verification and process development for advanced low-loss magnetic materials, high-insulation heat-resistant wires, and thermally conductive potting compounds.
03
Full-life cycle reliability verification system
We have established a full-process quality control system covering everything from characteristic testing of key materials (magnetic cores, magnet wires, insulation materials) to finished product electrical performance testing (ratio, withstand voltage, insulation resistance, temperature rise, efficiency), environmental adaptability testing (high temperature & high humidity, thermal shock, vibration), and long-term accelerated life testing.
This ensures high reliability and long service life of products under harsh application conditions.
