Dry-Type Power Transformers
Structural Innovation of Type SCB
Dry-type transformers feature low loss and low noise, with remarkable energy-saving effects and no need for maintenance. They have excellent heat dissipation performance, strong overload capacity, and can operate with short-term excess capacity when using forced air cooling. Additionally, they possess a certain degree of moisture resistance and can adapt to harsh environments with high humidity.

Product overview
Core Performance Advantages
Dry-type transformers feature low loss and low noise, with remarkable energy-saving effects and no need for maintenance. They have excellent heat dissipation performance, strong overload capacity, and can operate with short-term excess capacity when using forced air cooling. Additionally, they possess a certain degree of moisture resistance and can adapt to harsh environments with high humidity.
Technical and Structural Features
Manufactured with advanced domestic technology, they boast high mechanical strength, strong short-circuit resistance, minimal partial discharge, and good thermal stability, which ensures reliable performance and a long service life. Equipped with a comprehensive temperature detection and protection system, the intelligent signal temperature control system enables automatic monitoring of the three-phase winding temperature, automatic start and stop of fans, as well as alarm and trip functions. Moreover, the product has a small size, light weight, occupies little space, and requires low installation costs.
Due to their strong short-circuit resistance, low maintenance needs, high operating efficiency, small size, low noise, safety, fire resistance, pollution-free operation, and ability to run under high loads, they are often used in places with high requirements for fire and explosion protection-such as large shopping malls, hospitals, chemical enterprises, and other areas that have strict demands on the safety and stability of power equipment.
Design features
What the design is built around
Cast-resin insulation
Epoxy resin encapsulation protects windings from dust, humidity and accidental contact.
Fire-safe design
No insulating oil is used, making the unit suitable for indoor and fire-sensitive buildings.
Low partial discharge
Vacuum casting and controlled curing keep partial discharge low over the service life.
Low noise
Core and clamping design reduce structure-borne noise for hospitals, offices and data centres.
