YB-40.5/0.8 -3200 PV Prefabricated Substation
The prefabricated substation consists of HV system, transformer and LV system. It is integrated in the box according to a certain wiring mode. As a miniaturized substation, it is applicable to urban grid construction and reconstruction. It is a brand new substation emerging after civil substation.
Application Scenarios
Applicable to places requiring flexible power supply such as new-energy wind and PV power stations.
Technical Features
Good completeness
Flexible combination and factory prefabrication, to realize complete supply of equipment
Small floor area
It is only 1/10 ~ 1/5 of the conventional substation with the same capacity, so that construction and time costs can be saved
Convenient maintenance
Modular design is adopted, and equipment can be maintained and replaced efficiently and conveniently
Movability
Fully enclosed steel structure box, with multiple protection functions, easy to move, with good adaptability
Safe and reliable
It has a variety of protection functions, featuring stable operation and work safety
