YBM, YBP Reihe von Umspannwerk (European patt

YBM, YBP series of prefabricated substation is the compacted sets of power distribution equipment combined by the high-voltage electrical equipment, transformer, and low voltage electrical equipment. And it is commonly known as the European pattern box substation. It is used in skyscrapers, urban and rural construction ,residential ,high-tech development zone, small and medium-sized factories, mines and oil fields, and temporary construction sites to receive and distribute the electric energy in the power distribution system.YBP series of prefabricated substation has the features or strong set ,small size compact safe and reliable operation, easy maintenance, and mobility .It only took 1/10-1/5 area of the conventional substation of the same capacity, and thus greatly reduces the workload of the design and construction ,and reduce the construction cost. It can be used in the ring distribution system, and can also be applied in the double power distribution system and radiation terminals distribution system. It is the new set of equipment used in the transformation and construction of rural and urban substation. YBM, YBP series of prefabricated substation comply with the SD320-1992 "box substation technology" and the standard of GB/T17467-1998 "high-voltage on the whole Sichuan prefabricated substation". The shell material can be selected according to the user's demand for non-mental, composite or steel plate. Features of products 1: The ZGS11 series of prefabricated substation is developed on the basis of combination of the latest foreign advanced technology and the actual situation. 2: It has the features of small size, easy installation, easy maintenance, and low noise. 3: Low loss, anti-theft, strong overload ability, and safe.
