1.Summary
ZBW series combined power distribution station is the power distribution equipment combining high voltage transformer.transformer and low voltage equipment that is used for city tall buildings urban&rural buildings,residence communities,medium&small factories,mines,oil fields and temporary electrical power consuming sites. The station function to receive and distribute power energy in power distribution system.
ZBW series combined transformer features compact structure,package unit,safe and reliable operation,convenient maintenance,attractive apperance,bigh mobility and small size.It can be used as loop network power distribution system.It is a new set of equipment for urban&rural transformer substation construction and drenovation.
ZBW series combined substation complies with the standards of GB/T17467-1998 High Voltage/Low Voltage Pre-Installed Transformer substation and IEC1330.
