Shenyang No.4 Transformer Factory — Founded in 1961, a pioneer in crude oil desalting and special transformers at home and abroad, with over 60 years of dedicated R&D and manufacturing.
The explosion-proof transformer for electrostatic desalting is a key component of the unit, with a capacity of 50–250 kVA. As a step-up transformer, it supplies AC or DC power, and our company can produce models up to 40 kV.
The electrostatic desalting unit consists of a large pressure vessel, powered by a high-voltage desalting transformer. Through electrode plates and demulsifiers, it efficiently removes salt and water from crude oil.
The device powers the electrodes inside the electrostatic desalting vessel, with one end connected to the transformer’s high-voltage side and the other linked to the vessel’s electrode plates via a discharge rod.
Used with the explosion-proof desalter transformer, this device enables on-load, uninterrupted stepless voltage regulation, meeting the crude oil desalting and dehydration requirements through voltage adjustment in the desalter system.
Submersible Pump Transformer – High efficiency, overload resistance, and reliable insulation. Available in multiple capacities and voltage levels, widely used in oilfield gathering, production, and energy extraction.
The dry-type transformer uses resin casting or air cooling without oil, ensuring safety, eco-friendly design and easy use. With broad capacity and reliability, it meets the power needs of electrostatic desalting and related systems.
The electric furnace transformer powers arc and refining furnaces, with high current, strong overload capacity, and stable voltage control. It runs reliably and meets the needs of smelting and heating in metallurgy and related industries.
The prefabricated substation combines high-voltage switchgear, transformer, and low-voltage gear in a compact unit. With small footprint and easy setup, it is widely used in industry, housing, and temporary power.
The combined transformer unites high-voltage switchgear, transformer, and low-voltage gear in a compact design. With easy transport and setup, it ensures reliable operation, suitable for urban grids and industrial systems.
The broadband transformer offers wide frequency response, high efficiency, and low distortion. With compact design, stable performance, and good cooling, it suits communication systems, power electronics, and test instruments.
The power transformer handles voltage step-up or step-down in power systems, with high efficiency, low loss, and reliable operation. Covering various capacities and voltage levels, it is widely used in grids, industry, and infrastructure.
