6.6 KV Outdoor Type Cast Resin Dry Type Transformer for Expressway


Product Description


  1. A prefabricated substation made of box materials, characterized by strong integration, small size, compact structure, safe and reliable operation, ease of maintenance, and mobility.
  2. The substation includes three compartments: high voltage, transformer, and low voltage.
  3. The high voltage compartment typically contains high voltage switchgear equipment, the transformer compartment has transformers, and the low voltage compartment has low voltage switchgear equipment.
  4. Common box materials include channel steel, aluminum alloy, and flame-retardant composite materials, which can be selected based on the site's requirements.
  5. The substation can be customized based on different power levels and voltage levels to meet various site requirements.
  6. Compared to traditional civil-built substations, the prefabricated substation requires less civil engineering work, has a smaller footprint, shorter construction time, and lower installation and maintenance costs.
  7. The prefabricated substation is suitable for a wide range of applications, including urban high-rise buildings, residential areas, industrial enterprises, mines, oil fields, and temporary construction sites.
  8. It is an efficient, safe, reliable, energy-saving, and environmentally friendly distribution equipment suitable for power distribution, control, and protection work in power systems.
