substation.
Product Description
ZBW packaged substation, also known as
prefabricated substation. It meet GB*********8 high and low voltage prefabricated
substation and IEC***0
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.
Â
The ZBW 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
Application
The type of small unattended substation is
applicable for voltage up to *5KV, with main transformer capacity
up to ***0KVA, is widely used in urban industrial substation, *0KV
ring network system, rural power grid *5KV 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.

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:
