American transformer is suitable for commercial centers, industrial parks, residential areas, streets, airports, docks, sheep stations, metro MAO city densely populated areas, and deep load centers, ring network and two-way power supply, one installation can achieve power supply transformer. It has the features of full insulation, full sealing structure, maintenance-free and easy installation.

The box type transformer compact substation is the integration of high and low voltage primary equipment, transformers, and secondary equipment in the factory in a double-layer, sealed, anti-corrosion, mobile outdoor box.

The box-type transformer is usually used as an intermediate link of power transmission and conversion, which is used to convert high-voltage power into low-voltage power to achieve power supply purposes. When the box-type transformer is powered, it is necessary to operate in strict accordance with the regulations to ensure the safe, reliable and normal operation of the operation process.

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.

Bare Aluminum wire, the fundamental conductor of other winding wires, is characterized as an electrician's round aluminum rod that is formed into different shapes of round or flat wire following a precise specification mold extrusion or drawing that is manufactured in compliance with client needs. After that, this wire is ready for coating procedures that involve the use of paint, paper, fiber glass, or other covering insulation insulating material. The product is used for winding transformers, generators, motors, reactors, and other electrical equipment, as well as for life wire supply.

As the basic conductor of other winding wires, bare copper wire is defined as an oxygen-free copper rod that is made into various specifications of flat wire or round wire after a specific specification mold extrusion or drawing is made in accordance with customer requirements. This wire is then prepared for coating processes using paint, paper, fiber glass, or other insulating material covering insulation. The product can be used for life wire supplies or winding of transformers, generators, motors, reactors, and other electrical equipment.

Polyester/Polyimide film covered winding wire is made by copper or aluminum conductor. At first wrapped polyimide film which is coated with adhesive material on the conductor, and sintered film and film,to make it with conductor together. After heating, the fluorine on the composite film is melted, so that the film and the conductor are bonded as a whole. This product has excellent voltage resistance, thin insulation thickness and heat resistance up to 220 ºC. It is mainly used for winding of motors, reactors, welding machines or other similar electrical products. The electrical bare copper (aluminum) wire produced by extrusion process is an ideal material for producing polyimide film clad wire.
