Resin-Insulated Dry Type Power Transformer

Epoxy resin is a widely used chemical raw materials, it is not only a flame retardant, flame retardant material, and has superior electrical properties, and then gradually used by the electrical manufacturing industry. Because epoxy resin has high insulation strength compared with air and transformer oil, and has high mechanical strength and superior moisture and dust resistance after pouring, it is particularly suitable for the manufacture of dry transformers.

Dry transformer is a kind of power transformer different from oil-immersed transformer, oil-immersed transformer is the use of transformer oil for insulation and heat dissipation, but the insulation material of dry transformer is mostly the insulation formed by epoxy resin pouring. 

The SG (B) 10 non-encapsulated Class H dry transformer is an insulation system based on insulating paper. Excellent electrical and mechanical properties are maintained throughout the service life of the transformer. The insulation paper is not easy to age, the shrink resistant agent is anti-compression, and the elasticity is very strong, so it can ensure that the coil of the transformer remains tight in structure even after several years of use, and can withstand the pressure of short circuit.

Non-encapsulated coil dry transformer is a special type of dry type power transformer.The iron core of the dry transformer is mostly made of silicon steel sheet and cast epoxy resin coil. The high voltage winding in these two sets of epoxy resin cast coil windings has a higher voltage than the low voltage winding, which has a lower voltage. To improve electrical insulation, an insulating tube is positioned in between the high and low voltage coils. Soft cushions support and fix the high and low voltage coils on the steel castings. 

The main components of a dry transformer include main wiring, high and low voltage winding, iron core and insulation materials. The main wiring of dry-type transformers is usually made of high-purity copper or aluminum, which can withstand the requirements of high temperature and high current. The high and low voltage winding is wound with special insulating materials to ensure the insulation performance of the transformer. The iron core plays the role of magnetic conductivity and support winding, which is usually composed of silicon steel sheets and has low magnetoresistance and loss. Insulation material is a very important part of dry transformer, it can effectively isolate high and low voltage winding, to ensure normal operation.

The dry type transformer is a type of transformer that does not use liquid coolant. Unlike traditional oil-immersed transformers, dry transformers use air as the cooling medium, so oil leakage, explosion and other safety hazards are eliminated. At the same time, the dry-type transformer also has the advantages of simple structure and convenient maintenance, which makes it widely used in all walks of life.

In the past more than 20 years, "sincere cooperation and customer satisfaction" has been our working mission. Known as a trusted business partner in the industry. We look forward to bringing "professional and convenient" customized experience and cooperation to the whole world.

The dry transformer consists an iron core which is made by silicon steel sheet, and epoxy resin cast coil. In these two forms of epoxy resin cast coil winding, the higher voltage is the high voltage winding and the lower voltage is the low voltage winding. An insulating tube is put between the high and low voltage coils to enhance electrical insulation. Soft cushions hold the high and low voltage coils securely on the steel castings.

For more than 20 years, our mission is "honest cooperation, customer satisfaction". "To be a trusted business partner" is the golden word. Bring "professional and convenient" customized experience and cooperation to customers around the world.

The dry transformer is mainly composed of an iron core that silicon steel sheet and epoxy resin cast coil. In these two groups of epoxy resin cast coil winding, the higher voltage is the high voltage winding, the lower voltage is the low voltage winding. An insulating tube is placed between the high and low voltage coils to increase electrical insulation. The high and low voltage coils are supported and fixed on the steel castings by soft cushions.

With over 20 years of experience in making transformer field, we are proud to offer a wide range of transformers, offer to different industrial and commercial needs. We anticipate working with you as a long-term partner in China.
