China Manufacturers Customization Outdoor Prefabricated Transformer Substation United Box Type Substation

Product description

Products meet GB17467-1998 "high and low voltage prefabricated substation" and IEC1330 standards. The voltage classes are applicable to 35KV and below, the small unattended substation, with main interior capacity of 2000KVA and below,

The prefabricated substation can complete the transformation, distribution, transmission, measurement, compensation of electrical energy, system control and protection as well as communication functions.

Box type substation is a compact complete set of distribution equipment that combines high-voltage switchgear, distribution transformer and low-voltage switchgear according to certain wiring scheme. Main components: transformer, high-voltage switchgear and its control equipment, low-voltage switchgear and its control equipment, corresponding internal connecting wire (cable, busbar, etc.) and other auxiliary equipment.

1. Small volume,compact structure,reliable power supply and easy for installation;it can be realize single power supply,double power supply,or ring net supply,with double-fuse protection,low running cost.
2. The casing surface is treated by electrostatic painting and has good wearing resistance.It is applicable to both ring network and single/double power supply,is convenient for shifting,and can enhance the reliability of power supply.
3. The transformer adopts environment-friendly S11 series spiral core,non-excited voltage regulation,full-enclosed type,featuring energy saving and low noise.The amorphous alloy transformer is also available if required by clents.HV load switches and protective fuse are placed in oil filled iron tank,and the tank is of full-enclosed structure.
4. The LV room is provided with watt-hour meters,voltmeters,and breakers of four outgoing lines,reactive power compensation can also be provided if necessary.
5. It uses S11 series spiral core transformer,its idle loss is 30%-40% lower than S9,and noise 7~10dB lower than S9.
6. The combination transformer is characterized by reliable power supply,reasonable structure,quick installation,flexible and easy operation,small volume,low construction cost,ect.
7. It is suitable for outdoor and indoor use,and is widely used in industrial parks,residential quarters,business centers and high risers.
