    Detailed Product Description

    ZBW Type Prefabricated Substation

    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.

    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 ZYDQ prefabricated substation is composed by the high-voltage switchgear, low-voltage distribution panel, distribution transformer and enclosure. The high-voltage switchgear adopts air 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

    ZYDQ prefabricated substation 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.

    prefabricated substation Technical Parameters

    Notes to the ordering of the Prefabricated Substation

    1. High voltage:

    Way of incoming: terminal type, ring type or double power in.

    Whether there is high voltage metering or not. If yes, the position of the meter(front of the switch or behind the switch), the requirement of the meter gauge and its supplier is designated or not.

    Type of the HV switch, one way is using the combination with high voltage vacuum load switch and the fuse, which is mainly used and economical; the other is adopting the disconnector switch and the vacuum breaker, which is used for the high capacity transformer and with higher price.

    2. Transformer: the transformer type, the connection group symbol, capacity and the impedance voltage of the transformer.

    3. Low voltage:

    Switch Supplier.

    The number of the outgoing ways and the rated current value of each outgoing switch.

    Whether there is the compensation or not, if yes, the capacity of the compensation.

    Whether with the metering or not. If yes, the position is necessary.

    4. Type of the busbar(copper or aluminum)

    5. Layout of the substation(whether with the operation corridor or not)

    6. The material of transformer enclosure: composite board (commonly used), steel plate, stainless board or cement.

    7. Delivery Period for prefabricated substation
