Introduction of Transformer Substation
• The box body adopts domestic leading technology, and the shell is generally made of galvanized steel plate. The frame adopts standard container materials and manufacturing techniques. It has good anti-corrosion performance and guarantees no corrosion for 20 years. The inner sealing plate adopts aluminum alloy buckle plate, and the interlayer adopts fireproof and thermal insulation materials, air-conditioning and dehumidification devices are installed in the cabinet, and the operation of the equipment is not affected by the natural climate environment and external pollution, and can ensure normal operation in the harsh environment of -40℃~+40℃.
• The product has a high degree of automation, perfect high and low voltage protection, safe and reliable operation, and simple maintenance.
• It occupies a small area, saves investment, has a short production cycle, is convenient to move, and has flexible and diverse wiring schemes.
• Factory prefabrication, as long as the designer according to the actual requirements of the substation, make a main wiring diagram and the design of the equipment outside the box, you can choose the specifications and models of the box transformer provided by the manufacturer.
• The transformer substation has a beautiful appearance and a variety of types, including general-purpose, villa-type, compact and other styles. By selecting the color of the box-type substation shell, it is easy to coordinate with the surrounding environment, which is especially suitable for urban construction.
• Transformer substations are vital for the stability and reliability of the electrical grid. They ensure that electricity can be transmitted over long distances with minimal losses and delivered safely to homes and businesses. Proper design, operation, and maintenance of these substations are essential for the overall efficiency of the power system.
