Unlike conventional oil-filled transformers, cast resin dry type transformers use solid epoxy resin insulation and contain no flammable insulating oil. This significantly reduces fire hazards, eliminates oil leakage risks, and minimizes environmental impact.
Reliable Operation in Harsh Environments
The encapsulated cast resin winding structure provides outstanding protection against moisture, dust, condensation, and contaminants. The transformer can operate safely even in environments with up to 100% humidity without requiring special dehumidification procedures.
Low Losses and High Energy Efficiency
Advanced magnetic core design and optimized winding technology help reduce no-load and load losses, improving overall system efficiency and lowering operating costs throughout the transformer’s service life.
Strong Overload and Short-Circuit Capability
Designed for demanding electrical networks, the transformer offers excellent mechanical strength and short-circuit resistance. It can operate continuously at 110% rated load with forced air cooling and withstand temporary overload conditions up to 150% rated load.
Low Noise Performance
Precision core manufacturing and high-quality materials contribute to reduced operational noise levels, making the transformer ideal for noise-sensitive installations such as hospitals, schools, office buildings, and data centers.
Intelligent Temperature Protection
Integrated BWDK series temperature monitoring devices continuously monitor winding temperatures for each phase, providing real-time temperature display, over-temperature alarms, and automatic trip protection to enhance operational safety.
