Cast Resin Transformer is one of the types of industrial transformers made by deleting dioteric fluid. That is, the coils are not immersed in the oil. Instead, it is replaced by solid objects. This type of transformer lacks oil and the coils are resin and are trapped with casting and resin injection. The most important advantage of these transmits is high thermal tolerance and elimination of oil fire risk.
Due to the removal of the tank in this type of transformers, it is possible to install it inside an enclosure for safety and safety.
1. Power-conveyors, which are responsible for transmitting electrical energy by changing voltage, are mainly designed in the form of free space (OUTDOOR) and the installation of ground or in-room indoor (Indoor).
2. Earth's transformers, which are actually a transformer to create the center of the star (null dot) in transmission posts and have no secondary coil for energy transfer.
3. Earth and Auxiliary Transphantomators, so-called compact = auxiliary and Grounding, are actually a combination of a land transformer with a distribution transformer in a device and is used to create the central point of the star and nutrition in the transmission posts. .
4- Special distribution techniques, mostly used for power supply of industrial units and in terms of specific technical specifications, such as power, voltage, phase number, connections, type of loading, environmental conditions, etc. are divided into different types that can be divided into different types that can Some of them, such as single -phase transformers, three -wires, rectifiers, furnaces, loaded voltage adjustment key (OLTC), compulsory cooling system, exit bushing from the walls, cable boxes and busDuct and with special protective equipment Are designed and manufactured.

resin transformer is usually used in moderate voltage conditions. The auxiliary services of electrical systems, posts, large factories or industrial factories, buildings, schools, shopping malls, residential energy supply and many other places are that this type of transmits its extraordinary applications. The operation and cost of buying and installing dry transformer can be considered the most important electrical equipment in any electrical system, which is why they must be protected to ensure their performance and maximize their life.

One of the many ways to classify transformers is based on the type of cooling. For example, for power transformers up to one kV nominal, natural convection cooling is often sufficient with fan help. Traditionally, oil transformers relied on highly refined mineral oil as a cooling environment, while with the latest generation of resin transformers, the transformer core is insulated with thin minerals. Another difference between these two types is the dry advantage of fire safety as well as the less environmental pollution in which it is installed. They can also be compared to noise pollution. The dry type is much more modern and more modern and economically, maintenance, tolerance against sudden load pressure and voltage changes more economical and superior.

The most obvious feature of this transistor is the non -use of oil. The magnetic circuit and coils are not immersed in an insulating liquid but are covered with a mixture of epoxy resin. Higher reliability is another feature of dry transformer. Casting is minimizing the precipitance of contamination and corrosive particles, as well as strong and waterproof. Active components are poured with resin mixture of quartz and epoxy resin after fabrication in the mold and pre -heating in the vacuum. In dry transformer, cast coils are divided into many strips that have only one round for each layer - which are divided into. Higher impact voltage resistance and less risk of minor discharge. The coil is usually made with aluminum tape, so the mechanical stresses caused by the transformer temperature change. Low voltage coils are manufactured by an aluminum or copper foil that provide strong resistance to short circuit stress because the dielectric stresses are very low. Another feature of the dry transformer is that the transformer core with high permeability steel sheets and high permeable steel sheets. Low -grain losses are designed to minimize wandering flux losses. The surface of the magnetic core is also covered by a special color that protects against oxidation and corrosion as well as noise reduction.
Types of Tranformatore
dry transformer is of two types.
Transformer Type of Resin casting (CRT)
Transformer impregnated with vacuum pressure (VPI)
Transformer Type of Dry resin casting (CRT)
The type of casting resin (CRT) is used in high humidity areas. Because its primary and secondary coils are enclosed with epoxy resin. This capsulation helps prevent moisture penetration and affect the coil material. Full protection is obtained by this casting resin so that the transformer can operate without impaired moisture -prone areas. So this is a non -moisturized transformer.

This type of dry transformer is made with minimal flammable materials as coil insulation. The coils of this transformer are made of foil or tape in a continuous layer. But for higher voltages, the coil is made of discs that are connected in a series or parallel according to the voltage surface. The coil insulation is saturated with a Class H polyester resin. The primary and secondary coils with the kernel are securely closed in a vacuum protective box. Protects high moisture penetration and is never affected by moisture.

Undoubtedly, resin dry transformers are a popular choice for use in commercial, industrial and residential locations. These power transists do not really need maintenance and have much less environmental impact than traditional transformers immersed in oil. Automatic extinguishers and other safety features make it a suitable option for internal applications or high -fire hostilities.

Another advantage of dry transformer is its intensive design. Depending on the nature of the design, resin transformers are more compact so they need less space than oil cooled units. Dry transformer also helps save on natural resources. Their structure and performance are environmentally friendly.
