1. YB H22- □ Series
Pre-fabricated Substation (European Type)
1. General introduction
YB □ series of products are designed for city power network
construction. This kind of product is a set of power distribution
device, which is assembled with medium voltage switchgear,
transformer, low voltage switchgear based on indicated
connection.
They are used for 3-phase AC system. 50Hz frequency, and
capacity less than 2500kVA in the residential districts, malls,
hotels, construction site, industrial & mining enterprise and
temporary workplace. Generally, they are suitable for ring
network power supply and redial terminal power supply.

3. Normal sercice condition
a. Ambient temperature^S'C -+4CC
b. The altitude should not be over 1000m and if use special transformer and LV components the altitude can up to 3800m.
c. Installation condition should not be severe shake and impact and the vertical lean angle should not be over 5C
d. The air humidity should not be over 90%(+25 °C)
e. The speed of outdoor wind should not be over 35m/s
4. Designation characteristics
a.The shell is designed in terms of advanced technology and actual situation. It has advantages of fastness, heat reduction
by ventilation, good performance, dust prevention, small animal prevention, moisture prevention, good appearance and
convenient maintenance. There are several kinds of material for choosing, for example, aluminum alloy plate, steel plate,
composite plate, stainless steel plate, non-metallic material.
b.The HV side usually uses load switch or vacuum circuit breaker, with a completed set of anti-misperation functions. If
the ring main unit switchgear (short as RMU) is selected as XGN20-12L SF6 RMU. HXGN15A, HXGN17, KYN28A, the
transformer can be oil-immersed, full-sealed or dry type transformer.
c.The substation has perfect protection performance, easy operation, and optional HV&LV measurement. The automatic
reactive power compensation device is able to be installed required by customer.
d.The cover of the substation is made of double layers. The gap between the two layers filled with foamed plastics to prevent
heat. There are independent separators inside the HV&LV room. In the transformer room, there are condensation prevention
device, automatic temperature monitor and heating & cooling devices.
Tank is designed as natural ventilation, also the forced ventilation equipment can be installed. The door and side plate
opposite the shutter should be fitted with anti-dust device.
