3150kVA Oil Immersed Power Transformer 22kV/400V Copper Winding

• 01 Specification Customization

  We support customized design of core electrical parameters for power transformers, including rated capacity, voltage level, short-circuit impedance, connection group, insulation class and cooling method. Our products cover a full range of specifications from 25kVA to 20000kVA and above, adapting to different power grid and load working conditions.

• 02 Structure Customization

  We can customize the overall structure of transformers according to installation scenarios, including oil-immersed fully sealed / fully corrugated / conservator structures, and dry-type cast / open / encapsulated structures. We also provide personalized design for enclosure forms (indoor/outdoor), installation methods (pole-mounted / pad-mounted / prefabricated substation) and heat dissipation configurations (natural air cooling / forced air cooling), meeting space constraints and protection class requirements from IP20 to IP54.

• 03 Accessory Customization

  We offer optional professional accessories as required, including temperature control/display devices, fan cooling systems, on-load tap changers, pressure relief valves, gas relays, intelligent monitoring modules (IoT terminals), protective relays, anti-corrosion coatings/stainless steel enclosures, etc., realizing full-featured configurations from basic protection to intelligent operation and maintenance.

• 04 Special Environment Adaptation

  For special working conditions such as high altitude (≥3000m), high/low temperature (-40℃~+55℃), coastal salt spray, chemical corrosion, dust and humidity, and earthquake zones, we provide customized protection solutions, including enhanced insulation for high altitude, anti-condensation and moisture-proof systems, anti-corrosion coatings, seismic reinforcement structures and dust-proof sealing treatment, ensuring stable operation of transformers in extreme environments.

• 05 OEM/ODM Services

  We provide full-process OEM/ODM services for power transformers. We can customize nameplates, appearance coatings and packaging according to customers' brand requirements, or deeply participate in project R&D, from preliminary scheme design and drawing optimization to sample trial production and mass production, to create exclusive transformer solutions for customers, adapting to various fields such as new energy, industry, construction and power grid projects.
