Product Description
ZBW packaged substation, also known as prefabricated substation. It meet GB17467-1998 “high and low voltage prefabricated substation” and IEC1330 standards etc. As a new type of power supply and distribution device, has more advantages than traditional civil substation. Such as smaller size, smaller floor area, compact structure, flexible movement, which greatly reduce period and area for construction in site, also the construction cost. Meanwhile, prefabricated substation is easy to be installed at site , can realize rapid power supply, almost maintenance free. Most particularly, it is placed at load center so that reduce power loss effectively to improve power quality, enhance the reliability of power supply and also is significant for distribution network transformation.
This substation fulfills the functions such as transformation of energy, distribution, transmission, metering, compensation, system control, protection and communication.
The ZBW prefabricated substation is composed by the high-voltage switchgear, low-voltage distribution panel, distribution transformer and enclosure. The high-voltage switchgear adoptsair load switch and the transformer is dry-type or oil immersed type. The substation adopts good ventilation structure with elegant appearance and good heat-insulating performance. The temperature rise of the compartments caused by the outdoor solar radiation can be reduced to within the lowest limits on account of the upper and lower ventilation windows. The forced ventilation device and the temperature auto-controlled device should be installed in the substation. The systems of control, protection, live display and the lighting are equipped in each separate unit.
Product Features
Application
The type of small unattended substation is applicable for voltage up to 35KV, with main transformer capacity up to 5000KVA, is widely used in urban industrial substation, 10KV ring network system, rural power grid 35KV substation and other occasions.
Main Function
This substation fulfills the functions such as transformation of energy, distribution, transmission, metering, compensation, system control, protection and communication.
Main Characters
The primary and secondary equipments are pre-installed in the cabinet which is removable, full-sealed, automatic temperature controlled, antiseptic, damp proof and rustproof. It only needs to be installed on the cement foundation after arriving at the site. This kind of substation have the advantages of low investment, short construction period, small occupation area and easy environmental coordination.
