10kV SCB12 Dry Type Transformer

The working principle of dry-type transformers is based on the law of electromagnetic induction, that is, a changing magnetic field will generate an induced electromotive force. Dry-type transformers consist of two parts: the primary coil (high voltage side) and the secondary coil (low voltage side). When an alternating current flows through the primary coil, an alternating magnetic field is generated. The secondary coil surrounds the primary coil, and when the current in the primary coil changes, an induced electromotive force is also generated in the secondary coil, thereby generating a voltage in the secondary coil.

Dry-type transformers have a wide range of application scenarios, including local lighting, high-rise buildings, airports, docks, CNC machinery and equipment, etc. Due to their excellent performance, dry-type transformers are also widely used in industrial production, aerospace fields, and medical equipment.

Because dry-type transformers have the advantages of strong short-circuit resistance, low maintenance workload, high operating efficiency, small size, and low noise, they are often used in places with high requirements for fire prevention and explosion prevention.
1.Safe, fireproof, pollution-free, and can be directly operated at the load center;
2.Adopting domestic advanced technology, high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability, and long service life;
3.Low loss, low noise, obvious energy-saving effect, and maintenance-free;
4.Good heat dissipation performance, strong overload capacity, and can increase capacity operation when forced air cooling;
5.Good moisture-proof performance, suitable for operation in high humidity and other harsh environments;

1. 0 - 40 (℃), relative humidity <70%;
2. Altitude: no more than 2500 meters;
3. Avoid exposure to rain, moisture, high temperature, high heat or direct sunlight. The heat dissipation vents should be at least 40cm away from surrounding objects;
4. Avoid working in places with corrosive liquids, or gases, dust, conductive fibers or metal shavings;
5. Avoid working in places with vibration or electromagnetic interference;
6. Avoid long-term inverted storage and transportation, and avoid strong impact

SCB12/10KV (12KV) (20KV) (24KV) (35KV) series epoxy resin cast dry-type distribution transformers
- Low loss, energy saving and environmental protection, 35% energy saving compared to SCB11 type transformers
SCB12 dry-type transformers are a high-quality, high-performance power equipment. Its main features include:
High reliability: Adopting dry insulation structure, there is no risk of oil leakage, which can effectively prevent transformer failure caused by aging or leakage of liquid insulating medium.
High environmental adaptability: Dry insulation structure makes the transformer more adaptable to harsh environmental conditions, such as high temperature and high safety requirements, and can operate stably.
Good safety performance: Dry insulation structure avoids oil pollution and fire risks, greatly improving the safety performance of the equipment.

High weather resistance: Dry insulation structure makes the transformer have good weather resistance, can operate for a long time under harsh climatic conditions, and reduces the frequency of equipment maintenance and replacement.

Energy saving and environmental protection: Dry insulation structure reduces energy loss, does not require the treatment and management of liquid insulating materials, and meets environmental protection requirements.

Good moisture-proof performance: it can be put into operation without pre-drying after shutdown.

Low loss: low partial discharge, low noise, and can operate at 120% rated load under forced air cooling conditions.

Perfect temperature protection control system: equipped with a thermostat, a platinum resistor (Pt100) is placed in the pre-buried hole on the top of the low-voltage coil to monitor the temperature rise of the transformer winding, automatically start and stop the cooling fan, and have fault alarm, over-temperature alarm and over-temperature tripping functions, providing a reliable overload protection device for the dry-type transformer, thereby improving the safety of dry-type transformer operation.
