Transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. Distribution cabinet manufacturer

Transformers can be divided into: distribution transformer, power transformer, fully sealed transformer, combined transformer, dry-type transformer, oil immersed transformer, single-phase transformer, electric furnace transformer, rectifier transformer, reactor, anti-interference transformer, lightning protection transformer, box type transformer test transformer, angle transformer, high current transformer, excitation transformer, etc.

Transformer is the basic equipment of power transmission and distribution, which is widely used in industry, agriculture, transportation, urban communities and other fields. In China, there are about 17 million transformers operating in the network, with a total capacity of about 11 billion kVA. The transformer loss accounts for about 40% of the power loss of transmission and distribution, and has great energy saving potential. In order to accelerate the promotion and application of high-efficiency and energy-saving transformers, improve the utilization efficiency of energy resources, and promote green, low-carbon and high-quality development, in January 2021, the Ministry of industry and information technology, the State Administration of market supervision and the National Energy Administration jointly formulated the transformer energy efficiency improvement plan (2021-2023).
