Transformers for Power Distribution and Industrial Applications
SNTOOM (Shuntong Electric Co., Ltd.) designs and manufactures transformers for utilities, industrial sites, infrastructure, and OEMs. As a Chinese transformer manufacturer, we deliver standard and engineered units produced to national standards. Fast service and customization help match demanding schedules and site conditions.
Types of Transformers We Manufacture
Oil-Immersed Transformers
Oil-filled designs suit distribution and substation duty. Options include on-load voltage regulation and single-phase D11 models for rural or feeder projects. Explore our Oil-Immersed Transformers to align ratings, cooling, and accessories with your environment.
Dry-Type Transformers
Dry-type units support fire-sensitive or indoor spaces such as data centers, tunnels, and commercial buildings. SCB11 and epoxy-potted variants emphasize safety, low noise, and minimal maintenance. Review our Dry-Type Transformers for insulation class, temperature rise, and enclosure choices.
Special Transformers
Engineered builds, including salt bath furnace transformers and other custom designs, match unique electrical and mechanical needs. Our team configures ratios, impedance, cooling, and interfaces after project review. See Special Transformers for tailored options.
Key Specifications and Options
| Specification Area | Typical Choices & Notes |
|---|
| Voltage & frequency | Primary/secondary ratios per project; 50/60 Hz as required. |
| kVA/MVA rating | Size to load profile, inrush, growth, and duty cycle. |
| Vector group | Coordinate phase shift, harmonics, and protection. |
| Cooling | Oil radiators for outdoor duty; dry-type air/encapsulation indoors. |
| Insulation & temp rise | Match ambient, altitude, and lifecycle targets. |
| Tap changer | On-load for live regulation; off-circuit for preset steps. |
| Enclosure & IP | Indoor/outdoor protection against dust, moisture, and corrosion. |
| Terminations & monitoring | HV/LV bushings, sensors, and basic condition monitoring. |
Define voltages, frequency, rating, and vector group to ensure compatibility. Coordinate impedance with fault levels and acceptable regulation.
Applications for Transformers
Utilities and substations rely on stable distribution, padmount or yard installations, and voltage regulation under variable demand.
Industrial facilities require efficient, reliable power for process equipment and plant distribution. For harsh sites, see our Mine Transformers for mining-grade protection.
Transportation and infrastructure projects benefit from resilient, compact footprints and controlled noise. Dry-type designs suit enclosed rooms.
OEM equipment integration is supported with documentation, interface matching, and serviceability.
