Product Description

Prefabricated Substation (European style)

YB11-12/0.4-30~2500 prefabricated substation is suitable for the outdoor three-phase Ac 10kv distribution network with thehigh voltage side rated voltage of 12kv, low voltage side rated voltage of 0.4kv, transformer rated capacity of 2500kVA ollower and rated frequency of 50Hz, for distribution and acceptance of the power distribution system.The product is used as the transformation and distribution equipment for urban residential areas, development areas, gardenscenic areas, high-rise buildings, industrial and mining enterprises, etc, and also as the temporary transformation anddistribution equipment for oil and gas fields, large construction sites, etc.The product complies with GB/T 17467-2010 "HV/LV Prefabricated Substation"

Characteristics

YB11-12/0.4 prefabricated substation can be divided into three parts, i.e. HV chamber, transformer chamber and Lvchamber. Generally, it is arranged in Chinese characters "mu" and " pin", also can be arranged in other formsaccording to user's design requirements.The top cover of prefabricated substation adopts a double-layer structure with air interlayer, to effectively preventindoor temperature rise caused by heat radiation.The HV chamber is mainly equipped with gas-filed on-load switch, vacuum on-load switch, and fuse-combinedelectrical apparatus.The transformer chamber usually adopts natural air cooling mode, also adopts forced air cooling mode if necessaryThe LV chamber cabinet is the assembled GGD, Gcs, GCK cabinet with the screen-mounted panel.The power can be supplied through the terminal, ring network or dual power supply, etc.

Service Environment

1. Ambient air temperature: -25° C~+40° C 
2. Altitude: ≤ 1000m 
3. Outdoor wind speed: ≤ 35m/s 
4. Relative humidity: daily average ≤ 95%, and monthly average ≤ 90% 
5. Earthquake intensity: ≤ VIII 
6. Installation location: no fire, explosion hazard, serious pollution, chemical corrosion, or severe vibration. 
*Please consult us in case of service conditions that do not comply with the above-mentioned requirements.
