FAQ
1. Applicable places
--Suitable for indoor environments with high requirements for safety and noise control, such as hospitals, schools, shopping malls, etc.
2. Warranty period
--Standard warranty is 24 months, calculated from the date of shipment. Extended warranty is also available upon customer request.
3. Required installation clearance
--Refer to the outline drawing for transformer dimensions. Suitable for power stations or industrial sites with limited space. A minimum clearance of 600 mm around the unit is recommended for heat dissipation and maintenance access.
4. Altitude and temperature limitations
--Standard: –5°C to +40°C.
5. Cooling and temperature rise control
--Adopts ONAN (Oil Natural Air Natural) cooling method, no external fan required. Winding temperature rise ≤65°C, oil temperature rise ≤55°C, suitable for high-temperature environments up to 40°C. In actual operation, the secondary side temperature is controlled within 104.6°C.
6. Transport and storage
--Transport: Use enclosed vehicles to avoid rain and severe vibration. The product is fixed on a base and wrapped with protective materials before shipment.
--Storage: Keep in a well-ventilated, rain-protected area free from corrosive gases. Do not store outdoors.
