YBW-40.5 Prefabricated Substation


This series of prefabricated substation is a type of outdoor complete equipment with high voltage 40.5kV, low voltage 12kV (0.4kV), transformer capacity 800~20000kVA, frequency 50Hz and three-phase AC system, including 40.5kV main transformer box, 40.5kV switch box and 12kV (0.4kV) switch box. Boxes are connected with each other by cables, and 12kV (0.4kV) incoming and outgoing lines are all connected by cables. This substation is a new generation product to satisfy urban and rural power grids construction. It takes the role of receiving, converting and distributing electric energies, and features small volume, high completeness, easy installation, movability, low cost and safe operation.
