What Is a Dry Type Transformer?

A dry type transformer is a power transformer that does not use insulating oil as a cooling or insulating medium. Instead, it relies on air, vacuum pressure impregnation (VPI), or cast resin insulation to dissipate heat and ensure electrical insulation. This design significantly reduces fire risk and environmental pollution.

Manufacturers like Taili Electric Co., Ltd. design dry type transformers to comply with international standards such as IEC, IEEE, and ANSI, ensuring long service life and stable performance.

How Does a Dry Type Transformer Work?

A dry type transformer operates on the principle of electromagnetic induction. When alternating current flows through the primary winding, it creates a magnetic field that induces voltage in the secondary winding. Heat generated during operation is dissipated through natural air circulation or forced air cooling systems.

• No liquid coolant involved
• Low partial discharge design
• High thermal class insulation

Which Types of Dry Type Transformers Are Available?

Each type is engineered by companies such as Taili Electric Co., Ltd. to meet specific environmental and load requirements.
