I. Product Introduction
The SCB12 Series is a 10kV three-phase epoxy resin cast dry-type energy-saving transformer. It adopts a high-permeability silicon steel core and high-strength copper conductor windings, formed through a vacuum casting process. The transformer is oil-free, fire-resistant, and environmentally friendly.
The product complies with the GB 20052-2024 energy efficiency standard and is classified as a Level 3 energy-efficient dry-type transformer. It features low energy consumption, high safety, reliable operation, and maintenance-free performance, and is widely used in indoor power distribution environments requiring high standards of fire protection, moisture resistance, and safety.

III. Main Features
1. Energy Saving and Low Loss
Losses are significantly lower than those of SCB10 transformers, with reduced no-load and load losses, ensuring lower electricity consumption during long-term operation and meeting energy efficiency requirements for new projects.
2. Dry-Type, Oil-Free, Fire and Explosion Resistant
Epoxy resin casting provides flame-retardant and self-extinguishing properties. With no oil leakage or fire risk, it can be safely installed indoors, in basements, or near load centers.
3. Strong Short-Circuit Resistance
High mechanical strength windings and excellent insulation performance provide strong resistance to short circuits, lightning impulses, and mechanical shocks, ensuring stable and reliable operation.
4. Moisture and Dust Resistant
Capable of operating reliably in humid and dusty environments. After shutdown, the transformer can be restarted without drying treatment.
5. Maintenance-Free with Long Service Life
Oil-free design eliminates leakage and routine maintenance requirements, reducing operating and maintenance costs while ensuring a long service life.
6. Low Noise Operation
Optimized core and structural design effectively reduce noise, making the transformer suitable for residential areas, hospitals, schools, and other noise-sensitive environments.
7. Compact Structure and Easy Installation
No oil pit or fire wall is required. The transformer can be installed directly on the floor, occupying less space and simplifying construction.
IV. Application Scenarios
High-rise buildings, residential communities, commercial complexes, and office buildings
Hospitals, schools, airports, subways, stations, and data centers
Industrial parks, factories, distribution rooms, and basement power distribution systems
Shopping malls, hotels, municipal projects, and key fire protection facilities
Indoor power distribution projects requiring high standards of fire protection, moisture resistance, environmental protection, and safety.
