Dry type transformers, as the name suggests, do not use any liquid coolant for insulation. Instead, they rely on air or solid insulation materials to protect the windings and core. This makes them ideal for indoor applications where the risk of leakage or fire is a concern. Dry type transformers are also more environmentally friendly as they do not contain any hazardous liquids that can pose a threat to the Environment in case of a leak.

On the other hand, liquid-filled transformers use oil or other types of liquid coolant to insulate the windings and core. This type of transformer is typically used in outdoor applications where the risk of fire is lower, and the cooling properties of the liquid coolant are beneficial. Liquid-filled transformers are also more efficient at dissipating heat, making them suitable for high-power applications where heat generation is a concern.

Ground-mounted transformers are another common type of transformer that is used in electrical distribution systems. These transformers are typically installed on the ground, either in a Pad-mounted enclosure or on a concrete pad. Ground-mounted transformers are designed to withstand harsh weather conditions and provide reliable power distribution to nearby facilities.

China has emerged as a leading exporter and maker of transformers, offering a wide range of products to meet the diverse needs of the global market. Chinese transformer manufacturers are known for their high-quality products, competitive pricing, and innovative designs. Whether you are looking for a dry type transformer, liquid-filled transformer, or ground-mounted transformer, you can find a reliable supplier in China to meet your requirements.

One of the key components of a transformer is the core, which is responsible for transferring magnetic flux between the primary and secondary windings. Cold-rolled oriented silicon steel is commonly used in transformer cores due to its high magnetic permeability and low core losses. This type of steel is manufactured using a special process that aligns the crystal structure of the material in the direction of the magnetic field, making it ideal for transformer applications.
