Due to their advantages such as strong short-circuit withstand capability, low maintenance workload, high operating efficiency, small size, and low noise, dry-type transformers are commonly used in locations with high performance requirements such as fire protection and explosion prevention. They are safe, fire-resistant, pollution-free, and can operate directly under high-load power consumption.
Adopting advanced domestic technology, these transformers feature high mechanical strength, strong short-circuit withstand capability, low partial discharge, good thermal stability, high reliability, and long service life.
Low losses, low noise, significant energy-saving effect, and maintenance-free operation.
Good heat dissipation performance, strong overload capability, and capable of short-term overcapacity operation under forced air cooling.
Certain moisture resistance, allowing operation in harsh environments with high humidity.
Dry-type transformers can be equipped with a comprehensive temperature detection and protection system. An intelligent signal temperature control system is adopted, which can automatically detect and cyclically display the operating temperature of each of the three-phase windings, automatically start and stop the fans, and provide alarm and tripping functions.
Small size, light weight, small footprint, and low installation cost.
