Product overview:

The YB20 pre-installed European box-type transformer substation is a set of transformer and distribution equipment which includes a high-voltage switchgear, transformer and low-voltage switchgear. It has the following features: flexible configuration and compact structure. It can be matched with the high voltage load switch as well as an intelligent interface, so as to achieve a 'four remote control' system. This transformer substation is the best choice for city power grids, landscape areas, squares, gardens and residential areas.
