6.6 KV Outdoor Type Cast Resin Dry Type Transformer for Expressway
Product Description
- A prefabricated substation made of box materials, characterized by strong integration, small size, compact structure, safe and reliable operation, ease of maintenance, and mobility.
- The substation includes three compartments: high voltage, transformer, and low voltage.
- 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.
- Common box materials include channel steel, aluminum alloy, and flame-retardant composite materials, which can be selected based on the site's requirements.
- The substation can be customized based on different power levels and voltage levels to meet various site requirements.
- 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.
- 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.
- It is an efficient, safe, reliable, energy-saving, and environmentally friendly distribution equipment suitable for power distribution, control, and protection work in power systems.
