Parameter Explanations
Rated Capacity: The capacity that a transformer can continuously transmit under rated voltage and rated current conditions, which is the apparent power of the transformer.
Rated Voltage: The designed voltage value for the transformer to operate continuously over a long period.
Short-Circuit Impedance: The impedance value obtained from the short-circuit test of the transformer, reflecting its current-limiting capability during short circuits.
Protection Grade: Indicates the transformer's enclosure's ability to protect against solid foreign objects and water.
Application Scenarios: The main places and environments where the transformer is applied.
Insulation Class: The thermal endurance class of the transformer's insulation materials, determining the maximum allowable operating temperature of the transformer.
Cooling Method: The cooling method adopted by the transformer, such as natural air cooling, forced air cooling, etc.
The main products include oil immersed transformers, dry-type transformers, power transformers, amorphous alloy transformers, mining transformers, box type substations, high and low voltage switchgear and supporting products
