10kV SCB18 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.
