    Three‑phase Oil‑immersed Wound‑core Transformer

    The S-M.RL series three-dimensional triangular coil iron core transformer breaks through the traditional planar structure and adopts a three-phase symmetrical three-dimensional structure. The product’s three-phase iron core magnetic circuit is completely symmetrical, greatly reducing magnetic resistance, excitation current, and no-load loss. It is an energy-saving transformer that uses traditional materials but has lower operating noise and a more compact structure.

    The no-load loss is reduced by an average of 25% compared to the national standard S11 product, the no-load current is reduced by 60-80% compared to the national standard value, the noise is reduced by 7-10dB, and 20% of silicon steel sheets and 2-3% of copper are saved. The energy-saving effect is very significant. The S – MRL three-dimensional coil iron core transformer adopts a fully sealed structure with a corrugated oil tank, which has the advantages of low loss, low noise, beautiful appearance, excellent performance, maintenance free, and long service life. It is a new generation of high-tech, high-performance, green, environmentally friendly and energy-saving product among similar products.

    Product Details

    S-M.RL three-dimensional coiled iron core transformers can be widely used in power plants, power grids, petrochemicals, metallurgy, industrial and mining enterprises, urban infrastructure such as airports, subways, docks, and residential areas for 10kV and 6kV transmission and distribution systems

    Execution standard: GB/T1094.1、GB/T1094.2、GB/T1094.3、GB/T1094.4、GB/T1094.5、GB/T1094.10、GB/T25438、JB/T501、GB20052 The transformer products produced by our company meet the new version of the above standards.

    Usage environment:
    1. The altitude of the installation site shall not exceed 1000m, and the ambient temperature shall not exceed 40 ℃ (special design may be carried out if this requirement is exceeded).
    2. The usage environment has a relative humidity of 100% and a temperature range of+40 ℃ to -25 ℃ (with requirements for on load switches and temperature controllers at -25 ℃).
    3. When installing the product, it should generally be 800mm away from walls and other obstacles, and there should be a distance of 300mm between adjacent transformers. The above distance can be adjusted appropriately for distribution boxes and other situations where installation space is limited.
    4. In general, transformers can be placed directly at the usage site and can be put into operation after installation and inspection. For situations with seismic and other special requirements, the foundation for installing transformers should be embedded with bolts and fixed with bolts and nuts.
    Adopting a three-dimensional triangular coiled iron core structure and a fully sealed corrugated oil tank structure.
    Rated capacity (kVA): 30-2500; High voltage: 6, 6.3, 10kV ± 2 × 2.5%; Low voltage: 0.4kV; connection group Yyn0, Dyn11; Impedance voltage 4%, 4.5%, 5.0%; Divided into S13 M.RL Level 3 energy efficiency, S20 M.RL Level 2 energy efficiency, and S22 M.RL Level 1 energy efficiency.
