Dry-type Transformer
Suitable for important places such as urban power grids, underground power stations, laboratories, business centers, theaters, hospitals, hotels, tunnels, stations, docks, airports, etc.
Oil-immersed Transformer
An energy-saving power supply mode suitable for urban power grid renovation and high-voltage users in every household. Transformers can be installed directly on platforms or hung on utility poles. It has a very significant energy-saving effect on electricity.
Feeder Transformer
The gear of the on load tap changer can be automatically adjusted according to the voltage condition of the line to achieve changes in the transformer ratio, thereby ensuring that the output voltage is stable within a certain range.
Transformer Core
Iron core products are mainly used for producing oil immersed transformer cores of 110kV and below, with a capacity of 30000 kVA and below, and dry-type transformer cores of 35kV and below
Combined Substation
The high and low voltage side switches are arranged in parallel, and the structural space is clearly separated· The maintenance and operation of high and low voltage switches are simple and convenient. Product purpose: The equipment is suitable for outdoor special environments in photovoltaic or wind power plants.
HV&LV Distribution Cabinets
In the power supply system, it is also used for breaking load current, short-circuit current, and making short-circuit current. The machine can be operated manually or electrically. Grounding switch and partition to be equipped with manual operating mechanism.

People in the transformer industry know that for the preparation of structural parts before cutting, accuracy and efficiency are the key factors affecting product quality and cost. The specific process requires comprehensive materials, structures and other factors, but the efficiency of most processes is very low. In order to solve this problem, Henan diteli Electric Co., Ltd. has always regarded quality as the foundation of enterprise development. The company took the lead in introducing an advanced laser cutting machine with fully automated cutting. At present, the product has been put into production.

Installation, use and maintenance of high power voltage stabilizer
When the input voltage exceeds the range, the output voltage will change. If the range is exceeded, the machine will automatically protect without voltage output, which will protect the electrical appliances and the machine itself. If the user needs to continue to use electricity, the mains button can be activated. At this time, the voltage regulator outputs the mains and does not work;

Oil-immersed power transformer oil leakage treatment method
Transformer leakage can be roughly divided into sealing leakage and welding leakage. To deal with seal leakage, the main purpose is to improve the sealing quality. For example, if the fastening screws are invalid for casing, oil mark, radiator valve, large cover, on-load switch and other places containing seals, the sealing ring can be replaced or re-glued and sealed. To deal with welding leakage, repair welding can be adopted. In the process of dealing with any kind of oil leakage, the thick material method or lashing method should be prohibited.

What is the loss of the transformer during operation
When the primary winding of the transformer is energized, the magnetic flux generated by the coil flows in the iron core. Because the iron core itself is also a conductor, an electric potential is induced on the plane perpendicular to the magnetic field lines. This electric potential forms a closed loop on the section of the iron core. And generate current
