Substations 12KV 24KV 36KV PV American 11kv Substations

Small volume, compact structurem reliable power supply and easy for installation; it can realize single power supply, double power supply, or ring net supply with double-fuse protection, low running cost.The casing surface is treated by electrostatic painting and has good wearing resistance.

    PV American 11kv Substations

    Main Function And Features 

    It is a low volume, compact construction, reliable power supply that is simple to install. It has the ability to operate at a cheap cost and may be used as a single, double, or ring net supply with double-fuse safety.Electrostatic painting is used to treat the casing surface, which results in good wear resistance. It is useful for shifting, works with both single and double power supplies, and can improve power supply reliability. The transformer uses an environmentally friendly spiral core from the S11 series, has full-enclosed design, non-excited voltage management, and is quiet and energy-efficient.In the event that clients need it, the amorphous alloy transformer is also available. The entire enclosed construction of the oil-filled iron tank holds the HV load switches and protection fuse. Watt-hour meters, voltmeters, and breakers for each of the four outgoing lines are installed in the LV room. Reactive power correction is also available if needed.It has idle loss 30%–40% lower than S9 and noise level 7–10dB lower than S9 since it employs S11 series spiral core transformers. 

     

    Applications Of Products 

    The combination transformer is widely used in business centers, residential complexes, industrial parks, and high-rise buildings. Its features include a dependable power supply, a reasonable structure, fast installation, flexible and easy operation, small volume, and low construction costs.

    Environment of operation. 
    The ambient temperature is between -30°C and +40°C at its lowest point. 
    Elevation: 1000 meters or less; 
    Wind speed of about 34 m/s; 
    Humidity: the average monthly relative humidity does not exceed 95%, nor does the average daily relative humidity exceed 95%; 
    Shockproof: no more than 0.4 m/S2 of horizontal acceleration and 0.15 m/S2 of vertical acceleration is allowed; 
    The maximum inclination at the installation site is 3°.
