GGD1 Low-voltage Fixed Switchgear
ZBW Prefabricated Substation (European)
■Overview
ZBW series prefabricated substation (European) is a series of products designed and developed by our company to meet the needs of urban network construction. This series of products is a complete set of power distribution equipment that combines medium voltage switchgear, transformer and low-voltage power distribution equipment into one unit.
This series of prefabricated substations is suitable for 12kV, three-phase AC system with rated frequency of 50Hz. The capacity is set in residential quarters of 2500kVA and below, commercial buildings, large-scale construction sites, high-rise buildings, industrial and mining enterprises and temporary construction sites. Ring network power supply is also suitable for radial terminal power supply. The prefabricated substation of this series has the advantages of compact structure, strong set, safe and reliable operation, convenient maintenance and beautiful appearance. It has small volume, small floor space, large selectivity, small on-site installation and short installation height cycle. And the characteristics of moving with the load center.
Use environment
Ambient air temperature does not exceed +40 ° C, minimum ambient air temperature - -25 C; altitude does not exceed 1000 m, if special transformers and low-voltage components are used, the vertical inclination of up to 3000 m can not exceed 5 °, no Places with severe vibration and no impact; air humidity not greater than 90% (+25C); no conductive dust, no explosion hazard, no corrosive metal and electrical components of gas places; outdoor wind speed does not exceed 35m / s.
Model and its meaning
■Product design features
The main technical parameters
Overview
The box body of the prefabricated substation of this series is mainly composed of a base, a side plate, a partition plate, a door and a top cover, and the box body is divided into a high pressure chamber, a transformer, and a low pressure chamber. The protection level of the cabinet is IP23. The sealing plates, partitions, doors and top covers above the base are made of cold-rolled steel sheets. Connected together by welding or fasteners. Have enough mechanical strength. The inner and outer surfaces of each part of the box are sprayed to form a durable protective layer. The cabinet is protected from rain, sun, rust and ventilation as the most advanced structure at home and abroad.
