Key Product Features

Absolutely Safe and Reliable

Fireproof and Flame-Retardant: Vacuum-cast with epoxy resin, possessing self-extinguishing properties, eliminating fire and explosion risks.

Environmental Adaptability: Excellent moisture resistance allows operation in 100% humidity environments without pre-drying.

Robust and Durable: Strong mechanical resistance with an expected lifespan of up to 30 years.

Energy Saving and Flexible Operation

Low Loss and Low Noise: Utilizing high-quality cold-rolled grain-oriented silicon steel sheets and advanced foil winding technology.

Strong Overload Capacity: In forced air cooling (AF) mode, the transformer's capacity can be increased by up to 50%.

Yes, we support customized services including parameter adjustments for power, size, input/output voltage, protection level (IP level), and working environment (such as explosion-proof or high temperature resistance).
2. Can you provide technical document support?
Yes, English manuals, product certificates, test reports, wiring diagrams, and other documents are provided. We also assist in completing necessary documents for import customs clearance.
3. How can I handle technical issues?
We provide 24-hour technical response via email, WhatsApp, or online meetings. Engineers can be arranged for on-site support in emergency situations.
4. What is the expected lifespan of these transformers?
Our dry-type transformers are built with robust integrally cast coils and have an expected operational lifespan of up to 30 years under standard conditions.
5. Is it safe to use in high-humidity environments?
Yes, the vacuum-cast epoxy resin design provides excellent moisture resistance, allowing it to operate in 100% humidity environments and restart after shutdowns without pre-drying.
6. What are the benefits of the Forced Air (AF) cooling mode?
In forced air cooling mode, the transformer's output capacity can be increased by up to 50%, which is ideal for handling emergency overloads and peak demand periods.
