Can you manufacture transformers with non-standard capacities?

Yes, we support custom-made transformers with special capacities. The lead time is 7-15 days, meeting individual needs.

Is it normal for the transformer to generate heat during operation?

Slight heat is normal. However, if the temperature is excessively high and the casing is hot to the touch, it is likely due to overload or poor heat dissipation, requiring shutdown and inspection.

Is maintenance expensive? What should I be aware of?

Maintenance costs are low. Regular ventilation and periodic dust removal are sufficient; frequent maintenance is not required.

What capacity should I choose?

Choose a capacity that is 1.2 to 1.3 times the total power of the equipment. This avoids overload and doesn't waste resources.

Are transformer capacity and power the same thing?

No. Capacity refers to rated apparent power (unit: kVA), while power refers to active power (unit: kW). When selecting a transformer, check the equipment power and convert accordingly.

Product Q&A

Q:How do I maintain the transformer daily?

Keep the surrounding area well-ventilated and dry, clean dust regularly, check that wiring connections are secure, and disconnect power when not in use.

Q:How long will this transformer last?

With normal use and regular maintenance, the all-copper model can last 10-15 years, ensuring durability.

Q:How do I choose between all-copper and aluminum wire?

Choose all-copper for stability and long lifespan; choose aluminum wire for limited budgets and short-term use.

Q:Is installation difficult? Do I need a professional installer?

We provide installation diagrams; you can install it yourself for simple situations; for complex scenarios, we can schedule on-site service.

Q:How long is the warranty period? What happens if it breaks down?

The whole unit has a 2-year warranty. During the warranty period, non-human-caused damage will be repaired or replaced free of charge.
