Five categories of transformers:

(1) Power transformer
Power transformers are mainly oil-immersed, and the product structure is two types: core type and shell type. The core-type process is relatively simple, while the shell-type structure and process are more complex. The shell type is especially suitable for high voltage and large capacity. It has advantages in insulation, machinery and heat dissipation, and is suitable for the transportation of hydropower stations in mountainous areas.
Power transformers are one of the main equipment in power plants and substations. The transformer can not only increase the voltage to send the electric energy to the electricity-consuming area, but also reduce the voltage to the voltage used at all levels to meet the needs of electricity consumption. Use transformers to increase voltage and reduce power transmission losses.

(2) Distribution transformer
Distribution transformer refers to a static electrical appliance used in the distribution system to transform AC voltage and current according to the law of electromagnetic induction to transmit AC power. There are round and oval core forms. Low-voltage coils are available in wound and foil types, and fuel tanks are available with radiator tubes and corrugated types.

(3) Dry-type transformer
The dry-type transformer is mainly composed of an iron core composed of silicon steel sheets and an epoxy resin cast coil. An insulating cylinder is placed between the high and low voltage coils to increase electrical insulation, and the coil is supported and restrained by a spacer, and its parts are overlapped with fasteners. All have anti-loosening properties. Dry change has four structures: epoxy resin casting, filler casting, wrapping and dipping. Because dry-type transformers have the advantages of strong short-circuit resistance, small maintenance workload, high operating efficiency, small size, and low noise, they are often used in places with high performance requirements such as fire protection and explosion-proof.

(4) Amorphous alloy transformer
Although amorphous alloy transformers have poor short-circuit resistance and high noise, they are energy-saving, so the future development prospects are considerable.

(5) wound core transformer
Wound core transformer is an energy-saving power transformer, which creatively reforms the laminated magnetic circuit structure and three-phase layout of traditional power transformers, so that the product performance is more optimized. Due to technical reasons, the production of three-dimensional wound core transformers is mainly concentrated in oil-immersed distribution transformers below 10kV and 315kVA, which are mainly used in rural power grid reconstruction projects.

"JECSANY" Transformers have stable quality and the products are exported to Southeast Asia, South Africa, South America, the Middle East and other global markets. OEM customization can also be made according to the drawings or samples provided by customers.
