Power distribution substation ZBW3-40.5

prefabricatedoutdoor

The ZBW3-40.5 series of prefabricated substations combine 35kV high voltage electrical, 35/10, (6), (0.4)kV power transformers, 10kV switch cabinets, 0.4kV low voltage cabinets, DC battery screens, and relay protection screens according to the predetermined plan A set of high-voltage substations combined together. There are two types of structure: integral type and split type. The frame is welded by section steel after protection treatment and covered with aluminum alloy plate; the top of the box is a double-layer hollow structure with a cut slope on the top surface to prevent water accumulation. The surface of the box is coated. The heat dissipation of the power transformer adopts a combination of natural ventilation and forced ventilation; the high and medium voltage switch room adopts air conditioning and anti-condensation devices to control temperature and humidity. Each function room and passage are equipped with lighting lamps for easy operation and observation. Urban high-rise buildings, urban and rural buildings, residential quarters, stations, docks, ports, parks, shopping malls, high-tech development zones, small and medium-sized factories, mines and oil fields, distributed photovoltaic power stations, temporary construction power and other places. •Passed the prototype test at an altitude of 4000 meters; •The high-voltage cabinet can adopt overhead or cable entry mode; •Compact structure and small size, the area of the product with the same capacity is only 1/10~1/5 of the conventional substation; •Anti-corrosion, waterproof, dustproof, fully enclosed, movable, with long-term outdoor use conditions, long service life, beautiful appearance;
