Distribution transformer

详情

S*3, S*1 series oil-immersed distribution transformers, after several generations of improvements

Strengthes:

• The core material adopts high quality high permeability cold rolled grain oriented silicon steel sheet, adopts 5 levels of stepping
• The core material adopts high quality high permeability cold rolled grain oriented silicon steel sheet, adopting *-stage step mounting, the magnetic flux distortion is reduced, effectively controlling the no-load current.
• The coil adopts flattening technology to increase the contact surface between the coil and insulation and improve the mechanical strength of the coil itself.
• The mechanical strength of the coil itself is improved.
• The total assembly adopts the upper and lower non-pressure ring structure, which fully ensures the smoothness of the oil channel and favors the heat dissipation of the transformer coil.
• Transformer coil heat dissipation, the lead wire adopts cold pressing technology, shorten the body baking time, improve the overall insulation strength.
• The transformer adopts vacuum oil injection process to ensure the stability of insulation performance and improve the life of the transformer.
• Compared with the standard, no-load loss is reduced by *5%, load loss is reduced by *5%, and no-load current is reduced by more than *0%. No-load current decreased by more than *0%.
  With reliablity, high performance, small footprint, good economy, widely used in agricultural network, compact substation, general industrial power consumption and other places.
