Product Description

Main working principle
Using the principle of electromagnetic induction, the input voltage and output voltage are converted by changing the ratio of the number of turns of the input winding and the output winding. At the same time, the input frequency and output frequency are converted by controlling the winding ratio of the input winding and the output winding.

Frequency conversion
Adjust the magnetic circuit parameters of the input winding and the output winding. For example, the magnetic permeability and magnetic resistance of the iron core. By increasing or decreasing the magnetic circuit parameters, the frequency is changed.
Among them, the magnetic permeability of the iron core is related to the volume, chemical composition of the material, heat treatment state, cold processing and temperature. The magnetic resistance of the iron core is affected by the material, the cross-sectional area of the iron core, and the magnetic flux density.
 
The products are mainly used in dry power plant boiler fans, water supply systems, and automatic control systems for metallurgy, the chemical industry, and urban municipal engineering.
Fully considers various types of medium and high voltage inverters, and carefully develops ZPSG type NOMEX insulated dry-type rectifier variable frequency transformer.

Factory Show

Types of transformers are used to step down three-phase medium voltage to low voltage for power distribution or distribution transformer.
Cast resin dry type transformer transformers are mainly used in urban environments (public buildings, offices, distribution stations), but are also used in industry.

Three Phase Dry Type Transformer Core 

The core is beveled and stepped for maximum performance and minimal bulk. After the magnetic steel is produced by the cutting machine, it is continuously cut into specific lengths by the automatic stacking machine, and then automatically stacked. The correct size is ensured during the entire stacking and assembly process to ensure the high quality of the product.

Dry Type Distribution Transformer Winding

The low voltage winding adopts the whole section of copper foil, which is wound on the special low-voltage foil winding machine with the F-grade insulation. The foil coil solves the outstanding problems such as low voltage, high current coil winding, high short-circuit stress, unbalanced ampere turns, poor heat dissipation effect, windingspiral angle, unstable manual welding quality and so on. At the same tim-e, the winding ends of our company aresealed with resin, cured and formed, moisture-proof and antifouling. The lead copper bar is automatically welded byargon arc welding.

Dry Type Power Transformer Accessories

All the accessories you need to customize our products to your needs.
The casing is made from bolts on a steel plate with removable panels for attachment and tape. Depending on the application and your requirements, the surface treatment can be galvanized, painted. The design is optimized to ensure the required cooling of the transformer at all levels of protection. The enclosure can be shipped assembled on the transformer or flat packed for on-site assembly.
