SG(B) 11H and SG(B)13H Epoxy Dry Type Power Transformer
The SG10 series epoxy resin dry-type power transformer is a new-generation product with the highest safety performance. All insulating materials are non-combustible, self-extinguishing and non-toxic, with combustible content less than 10% of traditional epoxy cast products, and no toxic fumes generated during long-term combustion at 800℃.
This product shows outstanding advantages in power, subway, shipbuilding, chemical, metallurgy and other scenarios with high safety requirements, high humidity and poor ventilation. Its special coil design, technology and materials achieve excellent three-proof performance (moisture-proof, mildew-proof, salt-fog-proof), can withstand thermal shock, and ensures zero cracking and zero partial discharge.With a new structure, materials and technology, the SG10 series features excellent heat dissipation, long thermal life and strong overload capacity, capable of long-term safe operation at 120% overload. It can operate at full load for a long time without forced air cooling in IP23 environment.
Product Features
1. Superior Safety Performance
Non-combustible, self-extinguishing and non-toxic insulation materials, with extremely low combustible content, meeting the highest fire safety requirements for public and industrial buildings.
2. Excellent Environmental Adaptability
Outstanding three-proof performance (moisture-proof, mildew-proof, salt-fog-proof), suitable for high humidity, salt-fog and harsh environments, with zero cracking and zero partial discharge.
3. Long Service Life & Reliability
Noex® insulation system ensures stable performance throughout the service life, with strong mechanical strength to withstand short-circuit impact and long-term overload.
4. Strong Overload Capacity
Can operate safely at 120% overload for a long time, and maintain full load operation without forced air cooling in IP23 environment.
Temperature control system
1. Basic Temperature Control Functions
- Natural cooling (AN): Alarm at 130℃ winding temperature, trip signal output at 150℃
- Forced air cooling (AF): Auto-start fans at 100℃, auto-stop at 80℃; Over-temperature alarm at 130℃, trip signal at 150℃
- All temperature points are factory-set, adjustable within ±20℃ as needed
2. Model Naming Rule (Temperature Controller): BWDK-5□□
| Symbol | Meaning |
|---|---|
| B | For transformer |
| W | Temperature component |
| D | Resistance type |
| K | Control type (X: Display type) |
| 5 | Temperature range 0-200℃ |
| First □ | Number of fans |
| Second □ | Fan current |
3. PC Interface Type Temperature Controller
The temperature control system collects temperature signals via PT100 thermistors embedded in low-voltage windings, displays each winding temperature intuitively, and supports computer interface for remote temperature monitoring.
