VOL TAGE PREFABRICATED
YB29—12/0.4prefabricated transformer substation
The YB29-/0.4prefabricated transformer substation has the advantange as
Following:
Factory run of transfomer substation not only shortens the construction period sharply but also reduces production cost ,go deep into the load center to the duffest extent,to improve the quallty of power supply and reduce line loss.Trinlty space.Various styleof appearance,elegant shape,it can be in harmony with surrounding environment.And the new inner stucture,which realizes the uniform of material saving and performance improving.with comfortable operation has the advantages of compact structure,complete funcions,safety and rellability,conventent maintenance.This series prefabricated substation has the advantanges of compact stucture,complete functions,safety and rellability,advantanges of compact structure ,complete function,safety and rellability，convenient maintenance，good appearance,small size.It suitable for the system of living area,commercial building,large building,mineral industrial enterprises and temporary construction site,adopt ring main unit supply or extensible power supply.
