introduction of SCB three-dimensional core transformer
GNEE TRANSFORMER supplies SCB three-dimensional core transformer.
SCB-RL series three-dimensional rolled-core dry-type transformer is an ideal distribution equipment with new magnetic circuit structure, high efficiency and low consumption, energy saving, safety and environmental protection developed by our company, which adopts three-dimensional triangular rolled-core components. After assembling and annealing, the three-phase magnetic circuit is completely symmetrical, reducing the magnetoresistance greatly and significantly and excitation current and no-load loss. After vacuum casting, the coil conductor and resin insulation layer form a complete rigid body, with good mechanical strength, strong ability to withstand short circuit, and good moisture and dirt-proof performance.
conditions of use
- Altitude
1000 meters and below;
- cool the air temperature
Maximum temperature: 40℃
The average temperature of the hottest month is 30℃
Maximum annual average temperature: 20℃
Minimum temperature: -25℃ (suitable for outdoor transformer)
Minimum temperature: -5℃ (for indoor transformer)
- Humidity
The relative humidity of the surrounding air should be lower than 93%, and there should be no water droplets on the coil surface.
If the use conditions exceed the above requirements, the operating parameters (such as output current, etc.) should be properly adjusted and appropriate protection measures should be taken to ensure the product operating life and safety and reliability.
