It is especially suitable for environments with:
- High humidity
- Heavy pollution
- Large load fluctuations
- Strict fire safety requirements
典型的應用包括
- Airports and power plants

常見問題
1️⃣ What is the difference between SGB and SCB transformers?
- SGB: VPI + NOMEX insulation (non-cast type)
- SCB: Epoxy resin cast insulation
👉 SGB is better for moist, polluted, and high-temperature environments, while SCB is better for indoor safety applications.
2️⃣ Can the SGB transformer operate in humid environments?
是的，它的功能：
- Hydrophobic insulation
- 防潮能力
- Fully sealed design
👉 Ideal for coastal and high-humidity areas.
3️⃣ Does it require forced cooling?
No, under normal conditions:
- Can operate at full load without forced cooling
- Supports overload operation
4️⃣是否提供遠端監控？
是的，它支援：
- 溫度監控
- 警報與保護系統
- Remote communication
