Products Description



 



The three phase dry type transformer is used in three-phase power systems to utilize air or another gas, not liquid, for cooling or insulation. Three phase dry-type transformers function like any other three phase transformer, stepping up or down the voltage as required. The transformer has three sets of windings on both the primary and secondary sides. It is designed to transfer electrical energy between circuits in a three-phase AC (alternating current) system, providing stable and device-safe electricity to consumers. Compared with oil-filled transformers, It is typically more compact and lightweight, making them easier to install and transport.

Three Phase Dry Type Power Transformers Feature



 



1. Low loss



The product no-load loss is 20% lower than the SC (B) 11 type product with an excellent energy saving effect, economic-efficient operation and without maintenance.



2. Low noise



The product noise level is 10-15 db lower than the existing professional standard JB/T10088-1999 Sound Level of 6-220KV Transformer.



3. Low partial discharge



Resin mixture adopts foreign leading-edge mixing method and film type vacuum deaerator to evenly mix the mixture and remove the bubble in the bottom part of mixture. The product has a low partial discharge which can be controlled at 5PC. Both high voltage and low voltage coils can be poured in vacuum pressure so as to enable a encapsulating of resin insulation and immersion among layers and inter-turns. The poured part has a compact solidity structure with anti-flaming, anti-explosion and environmental protection features.



4. Good material control



Glass fiber and other raw materials of winding coil have self-extinguishing property and will not produce arc due to short circuit. Resin will not produce harmful gas under high temperature.



5. Great mechanical strength



Resin with fillings can lower the differences of dilatation coefficient, cure shrinkage rate and internal stress as well as increase the hardness of condensate within the poured area. Precast and fashioned reinforcing materials are placed in the seal coat of epoxy resin, which is painted on the inside and outside surface of high and low-voltage coil. This can make the structure as compact as the reinforced concrete so that the mechanical strength is greater than epoxy resin. And it can bear the electro-dynamic action caused by sudden short-circuit without damage.



 





Application of three phase dry type transformer



 



The three phase dry-type transformer is widely used in various applications due to its safety, environmental benefits, and installation flexibility, such as commercial buildings, renewable energy systems, data centers, public utilities, industrial applications, urban installations, etc. This transformer suits our company's nail making machines, wire drawing machines, thread rolling machines, and other products due to its safety and durability in harsh conditions. It is resistant to dust, moisture, and corrosive environments.
