Product introduction
YB-40.5 combined substation is a three-phase AC 50Hz outdoor complete set of equipment with an upper voltage of 40.5kV and a lower voltage of 12kV (7.2). It is generally suitable for cities, towns, factories, oil fields and other places. It is also suitable for some large construction sites for receiving, converting and distributing electric energy.
Model meaning
Structural features
The substation generally adopts an \"H\" shape layout and is composed of a 35kV switchgear room, a 10kV switchgear room, an automatic control room, and a transformer level.
The box body is generally made of high-quality steel plates that have been surface anti-corrosion and spray-coated. Insulating materials are added in the middle to effectively ensure the normal operation of the temperature control system in the box.
