Dry type distribution transformer introduction
Dry-type distribution transformers, composed of iron cores and coils, offer advantages such as strong short-circuit resistance, low maintenance costs, low noise, and high efficiency.
Unlike oil-filled transformers, dry-type transformers do not suffer from issues related to oil leakage. They are typically used in medium voltage distribution systems, such as 11 kV/33 kV to 0.415 kV, and are widely employed in power stations, hospitals, and factories.
The reliability of the winding material is crucial for the safe operation and service life of the dry-type transformer, making winding temperature monitoring essential to ensure the transformer operates normally.

Features of dry transformer
- It is safe, fireproof, and pollution-free, and can be operated directly in the load center.
- It features high mechanical strength, strong short-circuit resistance, minimal partial discharge, good thermal stability, high reliability, and a long service life.
- It has low loss, low noise, and a significant energy-saving effect, and requires no maintenance.
- It offers good heat dissipation performance.
- It has excellent moisture resistance.
- Dry-type transformers can be equipped with a complete temperature detection and protection system. Using an intelligent signal temperature control system, the transformer can automatically detect and display the operating temperatures of the three-phase windings, start and stop the fan automatically, and provide functions such as alarms and trips. An RS485 communication interface can be installed for wireless detection and intelligent management.
- It is compact, lightweight, has a small footprint, and low installation cost.
Single Phase Dry Type Transformer Advantage
- Low loss, low noise, minimal partial discharge, and high reliability.
- Strong short-circuit resistance and high lightning impulse withstand capability.
- The HV coil is vacuum-cast with epoxy resin under pressure, which improves the quality of the casting.
- Simulation analysis is used for the core model to avoid resonance and reduce noise.
- Simulation calculations and analysis of lightning impulse waves are applied to HV coils, enhancing their lightning impulse resistance.
