• Nirxandin control sistemê serd kirina：Teknolojîya control sistemê serd kirina intelligent bikar anîn bi automatic operation equipment serd kirina li gor load û temperature transformer biguherîne. Mînak, divê transformer load light û temperature low, power equipment serd kirina automatically reduced û part of the cooling equipment stopped; Divê load increase û temperature rise, more cooling equipment started in time. Control intelligent dikare not only ensure the normal operation of the transformer, but also reduce the energy consumption of the cooling system and indirectly improve the overall efficiency of the transformer.

Rêbên bixebitina kapasiteyê

• Winding modified：Increase number of turns or wire cross-sectional area  Divê size yekem core transformer allow, number of turns winding û cross-sectional area winding wire dikare zêde bike. Increasing number of turns dikare improve voltage ratio transformer, û increasing cross-sectional area wire dikare hêza resistance winding bigihîne, allowing greater current pass through. Mînak, for step-down transformer, if number of turns low-voltage winding û cross-sectional area wire reasonably increased on basis of original, capacity transformer can be improved on basis of ensuring other performance.

• Multi-strand parallel winding used：Winding made by winding multiple wires in parallel. In this way, current carrying capacity winding can be increased, thus increasing capacity transformer. At same time, multi-stranded parallel winding can also improve heat dissipation performance winding to certain extent, which conducive to stable operation transformer under high capacity.
  

Insulation system optimized

• Use high performance insulation materials：Use new insulating materials, such as high-performance insulating paper, insulating paint and so on. These new materials have higher insulation strength and heat resistance, allowing higher voltages and currents to pass through without increasing the volume of the transformer. For example, the use of new nano-composite insulation materials can withstand higher electric field strength at the same insulation distance, which provides the possibility to increase the capacity of transformers.

• Use high performance insulation materials：Optimize insulation structure transformer, wê reducing air gap insulation layer û adopting compact insulation layout. Good insulation structure can improve insulation performance transformer, so that transformer can withstand higher voltage û greater current, thereby improving capacity transformer.
