Product Description


Oil-immersed transformer:
1. The transformer core is made of imported high-quality cold-rolled silicon steel sheet, which greatly reduces no-load loss and no-load current, and reduces noise.
2. The transformer is isolated from the air to prevent and slow down the deterioration of oil and insulation aging.
3. The transformer connection group adopts Dyn11 to reduce the influence of harmonics on the power grid and improve the quality of the power supply.
4. The transformer is a fully sealed structure, extending the service life, and free core maintenance.
5. The measured noise value is lower than the standard.
Excellent cooling performance:
Oil-immersed transformers use oil as a cooling medium, which can effectively take away the heat generated during the operation of the transformer and ensure the stability and safety of the equipment.
Good insulation performance:
Transformer oil has good insulation performance, can provide effective electrical isolation, and ensures the safe operation of the equipment.
Strong overload capacity:
Oil-immersed transformers can withstand large loads in a short period and have strong overload capacity.
Long service life:
Due to its design and material selection, oil-immersed transformers usually have a long service life and a low failure rate.

FAQ
Q:What is your terms of payment?
A:online fast payment,T/T
Q:Do you test all your chargers before shipping?
A: All major components are tested before assembly and each charger is fully tested before shipped
Q:How long to fully charge a car?
A: To know how long to charge a car, you need to know the OBC(on board charger) power of the car, the car battery capacity, the charger power. The hours to fully charge a car =battery kw.h/obc or charger power the lower one. For e.g, the battery is 40kw.h, obc is 7kw, charger is 22kw, the 40/7=5.7hours. If the obc is 22kw,then 40/22=1.8hours.
Q:Are you Trading Company or manufacturer?
A: We are professional EV charger manufacturer.
