The underground complete transformer was developed by our company based on the concept of “green” electric power and optimization of the urban environment, using advanced foreign technologies and integrating the principles of modern urban environmental design, providing for a gradual transition to underground installation of transformers.
An underground transformer is a switchgear in which the transformer and related auxiliary equipment are combined into a single unit. This equipment is installed under the surface of the earth outdoors, without direct contact with people, does not take up space on the surface of the earth and is well suited for urban environments, especially for densely populated central cities.
The SVR Linear Automatic Voltage Regulator is a device that automatically adjusts the transformer ratio of its own unit to stabilize the output voltage by monitoring changes in line voltage.
The intelligent transformer with on-load power control type S13-M.ZT has two fixed power levels and is able to automatically switch between them without turning off the power depending on load changes.
They are used as electrical equipment for lighting, power distribution or galvanic isolation of networks on ships, offshore platforms and other facilities. Marine lighting transformer is an important equipment.
Double guarantee of power supply safety: if a fault occurs in one power circuit, the other split winding continues to supply electricity. High-precision electromagnetic balance: the symmetry deviation of the split windings is less than 2%, which meets the requirements of ampere-turn balance.
High overload transformer (also called high capacity transformer) is a new type of transformer featuring high efficiency and low energy consumption, developed by our company through years of research. This transformer is continuously improved based on the design principles of transformers for medium frequency induction furnaces.
The furnace transformer is designed to power electric furnaces, converting the high input voltage into a lower voltage suitable for the operation of the furnaces. Widely used in the metallurgical industry: for steelmaking furnaces, ore-smelting furnaces, arc furnaces, resistance furnaces, salt baths, single-phase graphite furnaces, industrial frequency furnaces, as well as for electroslag remelting.
KBSG Mine explosion-proof dry transformer is intended for use in mines with the presence of a methane-air mixture and coal dust, which are hazardous due to explosion, as a switchgear for complex mechanized mining equipment in underground coal mines.
KBSGZY Mine explosion-proof mobile transformer substation is intended for use in mines with the presence of a methane-air mixture and coal dust, which are hazardous due to explosion, as a switchgear for complex mechanized mining equipment in underground coal mines.
Transformers of the KS series are distribution equipment for mines. These products are distinguished by their small dimensions, ease of descent into the mine, rational design, low losses and good heat dissipation properties.
SJCB Silicone Insulated Dry Type Transformer is a modern dry type distribution transformer that uses high quality silicone rubber as the insulating and sealing material.
