Products conform to the GB174671998 standards and IEC1330 standards.ZB type substation is commonly known as European transformer.
As a new type of power supply and distribution equipment, it has a number of advantages over building the traditional substation.Because of its small size, small covering area, and compact
structure,it is easy to move, it has greatly shortened the construc-tion cycle,and also reduces the cost.
What' s more, the substation is easy to install on site and work quickly.Equipment maintenance is simple, no special duty is needed, and in particular, it can be loaded in downtown centers, it
benefits quality of power supply, reduce power losses, and enhance reliability of grid. It means a lot to a new distribution network.
ZB type substation consists of high-voltage switch cubicle,low-voltage distribution panel, distribution transformer and the casing.There are air, vacuum, or SF6 loading switches for high voltage.
Transformers could be dry-type or oil-immersed. It adopts a goad heat radiation and ventilation structure. With goad appearance, it enjoys great thermal insulation performance. Besides, it is
equipped with upper and lower ventilation ducts, so temperature rise caused by outdoor solar radiation on the transformer roam and high/low voltage chamber can be reduced to a minimum.
It can be equipped with forced ventilation and automatic tempera-ture control. Each separate unit is fitted with perfect control,protection,and display device and lighting system.
