FAQ

 

 

Q: What is the maintenance cycle for this transformer?

A: Daily maintenance mainly involves periodic oil quality checks. The replacement cycle for insulation oil is generally 1-3 years, depending on operating conditions.

Q: Can it withstand overloads?

A: Yes. The insulation oil has a high heat capacity, so the oil temperature rises slowly during short-term overloads, allowing it to handle loads exceeding its rated capacity for a certain period. This is ideal for peak electricity consumption periods.

Q: Is this transformer suitable for outdoor installation?

A: Absolutely. Its fully sealed tank and highly weather-resistant surface treatment effectively protect against harsh natural environments like rain, snow, high temperatures, and humidity, making it an ideal choice for outdoor applications in rural and suburban areas.
