The primary winding initiates electromagnetic induction by generating a magnetic field when AC flows through it. Its number of turns directly affects the voltage and current transferred to the secondary winding.

The iron core serves a crucial role in the magnetic circuit of transformers, acting as its structural framework. Its design and manufacturing significantly influence various aspects of transformer performance, including losses, noise levels, insulation strength, and susceptibility to short circuits.

A liquid transformer is typically more efficient than a dry type. A wet type is smaller and needs less demand to make a conversion.

The most significant distinction between the two transformers is their cooling medium. Dry-type transformers employ air as a cooling medium, while oil-filled ones, as the name suggests, use oil.

On April 26, 2025, RAKHIMOV BOTIRJON, Chief Executive Officer of the Uzbekistan Branch of Shijiazhuang Tianya Electric Co., Ltd., and his delegation visited the headquarters of Shijiazhuang Tianya Electric Co., Ltd.

Power transformers have a voltage rating of more than 1 kV and can withstand short circuit currents up to a few hundred amperes. In comparison, distribution transformers have a voltage rating of less than 1 kV and can withstand short circuit currents up to tens of amperes.

The purpose of a power transformer is to convert voltage from a high voltage (transmission line) to a low voltage (consumer). The transformer is an electrical device that transfers electric energy by electromagnetic induction.

Oil-immersed power transformer is an indispensable and important equipment in the power system, its structure is complex and precise, and the components work together to ensure the conversion of voltage and the safe transmission of electric energy.

At around 7:30 on the 16th, "Bebinca" made landfall in Lingang New City, with a maximum wind of 14 (42 m/s) near the center of the landfall, becoming the strongest typhoon to land in Shanghai since 1949.
