Transformer can transformer the voltage of a network into the voltage matching the system or load and fulfill power transferring and distributing.Taking the place of transformers with silicon steel core, AMDT can be widely applied in outdoor power distribution networks systems, which is magnificently energy saving and can lessen air pollution. It is especially applicable for areas with insufficient power supply and fluctuating load and where daily maintenance is hard. Since the transformer adopts a fully sealed structure, the insulating oil and the insulating medium are not polluted by the atmosphere, so it can be carried out in a humid environment, making the ideal power distribution equipment in the urban and rural distribution networks.
The transformer core is made of imported high-quality cold-rolled silicon steel sheet, which greatly reduces no-load loss and no-load current. The core is tightly bound to ensure the compactness and reduce noise.
*� The high and low voltage windings are� made of oxygen-free copper. The low voltage winding of 500KVA and below is of double-layer cylinder structure, of 630kVA and above adopt double helix or four helix structure. High-voltage winding adopts multi-layer cylinder structure.
Dyn11 is used in the transformer connection group to reduce the influence of harmonics on the power grid and improve the quality of power supply.
*� The transformer is a fully sealed structure, with three coats of primer and one coat of finish paint applied on the inner and outer surfaces. The product is salt fog proof, moisture proof and fungus-proofing, beautiful, durable and reliable
The measured noise value is lower than the standard and maintenance free under normal operation.
1. Low energy consumption: The� adoption of isotropic soft magnetic material generates low magnetization power, high electrical resistivity and low eddy current consumption. The no-load loss and current of the core made of amorphous alloy are very low, only 1 / 3 of that of silicon steel sheet.
2. Strong corrosion resistance: the amorphous alloy core� is fully wrapped by resin and high temperature resistant silica glen� which� effectively prevent corrosion and falling off amorphous alloy fragments, and� provide better� protection for the core and coil.
3. Low noise. Improvement of� the structure of iron core and coil and� adoption� of special noise -reduction materials greatly reducing the operation noise.
4. Strong short-circuit resistance. This� product adopts three-phase five-column structure, and the iron core is protected by frame structure. Featured by low temperature-rise and strong heat dissipation, this� product� can work� by� 150% rated load under air cooling condition. Perfect temperature control protection system is applied� to provide reliable guarantee for safe operation of transformer
As the most widely used power facility, power transformers have a wide variety of types and are of great significance to energy conservation and emission reduction. The S13 fully-sealed oil-immersed power transformer is currently the main selection product for power distribution equipment, with significant energy-saving effects. At present, mainstream distribution transformers generally use S13 laminated core power transformers. It adopts a fully oil-filled sealed type, no oil conservator, and a corrugated sheet box structure. The volume of the transformer changes due to changes in temperature and load, which is completely adjusted by the corrugated oil tank. Its no-load loss is much lower than that of S9, and it is resistant to lightning impact It has strong short-circuit resistance, obvious energy-saving effect, and reduces the overall size of the transformer.
The S13 transformer is made of high-permeability oriented silicon steel sheet with a thickness of 0.27-0.30mm and a unit iron loss of 1w/kg, while the new S9 type is an ordinary silicon steel sheet with a thickness of 0.30-0.35mm and a unit iron loss of 1.20 -1.55w/kg. The S13 distribution transformers produced by our company all use 30P series high-permeability oriented silicon steel, using foil-wound coils and new insulating materials and processes. The product is resistant to high temperature, impact, and fully sealed structure design to ensure the stability of transformer oil quality It prolongs the maintenance cycle. At the same time, the integral fuel tank composed of corrugated fin radiator is produced by phosphating and multi-layer anti-rust spraying process, which has good weather resistance.

Product Details
It is the insulating sleeve that leads the transformer's internal high and low voltage leads to the outside of the oil tank, which not only insulates the ground as the lead, but also plays the role of fixing the lead.
Therefore, the transformer sleeve has the following requirements:
(1) it must have specified electrical strength and sufficient mechanical strength.
(2) must have good thermal stability, and can withstand the short circuit of the instant overheating.
(3) small appearance, small quality, good sealing performance, strong universality and easy maintenance folding.
Control transformers are mostly used for industrial applications where electromagnetic devices are used such as solenoids, contactors and relays. Also control transformers can be utilized in industrial electrical applications for regulating voltages through electrical and electronic circuits.

Resin cast current transformers are available for metering and protection application. These current transformers are mainly fabricated according to client’s specification. Ct coils are encapsulated in cast resin (polyester / epoxy). Secondary terminals are provided with either screws or studs. The main insulation between primary and secondary and earth is obtained by this epoxy resin. These transformers are of compact design with high mechanical and electrical properties. These are non-hygroscopic and hence give very good insulation properties even in given humid conditions.

We manufacture highly efficient and accurate resin cast potential transformers. These resin cast potential transformers are used in ac circuits, for the purpose of measuring large voltages. Their main function is to reduce the supply voltage to a small value so that it can be easily measured with standard low range ac instruments of moderate size and capacity. There are many advantages of using resin cast potential transformers for range extension of ac meters. We also offer resin cast potential transformers of dual purpose metering & protection that are also commonly used.
