Vehicular inverter transformer

Product description:
1. The product is applied to high-speed railway, subway, urban rail, etc.
2. Since the product is designed with low noise, strong overload capability and good capability in impedance short-circuit, it is characterized by high mechanical strength, high resistance to harmonic and high anti-vibration, and will not crack under the impact of high current and heat and has the free-hanging structure.
