Dry Type Transformer
Dry-Type Transformers for Industrial and Commercial Power Distribution
SUT Electrical supplies dry-type transformers for electrical distribution applications where installation environment, insulation design, and operational requirements are important considerations.
Main Product Types
-
Cast Resin Transformers: Use resin-encapsulated winding insulation in suitable transformer designs.
-
Non-Encapsulated Dry-Type Transformers: Use alternative solid insulation and winding arrangements.
-
Application-Specific Dry-Type Transformers: Configured for selected industrial and renewable energy applications.
Typical Applications
Dry-type transformers are commonly used in commercial buildings, industrial plants, infrastructure facilities, and suitable indoor substations.
Product selection depends on rated capacity, voltage, insulation class, cooling arrangements, enclosure design, and installation conditions.
Dry-Type Transformer Selection Guide
Choosing a dry-type transformer requires evaluation of electrical characteristics, insulation systems, temperature limits, and installation requirements.
Key Selection Parameters
-
Rated Capacity: Determine the required kVA rating and expected load conditions.
-
Voltage Ratings: Confirm primary and secondary winding voltages.
-
Insulation System: Distinguish cast-resin and non-encapsulated winding construction.
-
Thermal Performance: Verify insulation class, temperature rise, and cooling requirements.
-
Protection and Enclosure: Select appropriate enclosure arrangements where required.
-
Losses and Efficiency: Compare verified transformer loss data under defined conditions.
-
Installation Environment: Consider ventilation, ambient temperature, altitude, humidity, and available space.
