    I
    n case of any change in the external dimensions and weight provided in the instructions due to technical improvement, 
    the actual product shall prevail.
  • 1. Low No-load Losses

    Made of high-quality, high magnetically conductive, low-loss, cold-rolled grain-oriented silicon steel sheet.  Using a 45° fully-beveled seam and multi-stage step stacking structure, which effectively reduces no-load losses, no-load current and noise.

    2. Low Noise

    The noise is from the iron core, and is transferred to the surrounding through the housing. The connection joints are added with silicon sheet, which cuts off the noise spreading approach.

    3. Light Weight and Small Volume

    4. The Mobile Substation is explosion-proof and damp-proof.

    5. The Moble Substation has a perfect overload, short circuit and leakage protection. There is an electrical interlock or mechanical interlock device between the high- and low-voltage switches or between a high-voltage switch and a circuit breaker of the upper level.

    6. Energy Conservation and Environmental Protection

    1) Adopt a Nomex paper-wrapped line with insulation grade C that is imported from American DuPont Company. The product is air insulation and cooling. It has no pollution on the environment, and it has long service life; it can be decomposed for recovery after the service life ends;

    2) The high-quality 30Q130 cold-rolled oriented silicon steel sheet and oxygen-free copper conductor are adopted, so that the actual total loss is lower than that of the other similar products.It saves the energy, and lowers noise. The iron core surface is applied with the high-temperature-resistant rust-proof and damp-proof paint, Grade H insulation material is adopted for the iron core insulator, and there is no damage after operation at high temperature for a long term.

  • 1.The elevation shall not exceed 1,000m;

    2.Ambient temperature    Maximum temperature                              +40℃/104°F

                                            Maximum daily average temperature        +30℃/86°F

                                            Maximum annual average temperature     +20℃/68°F

                                            Minimum temperature                                -5℃/23°F

    3.The relative humidity shall not exceed 95% (at +25 ℃/77°F)

    4.Mines with a mixture of methane gas and coal dust, and a risk of explosion;

    5.Places without strong bump and vibration and with inclination from the vertical plane not exceeding 15°;

    6.No sufficient gas or vapour to cause metals corrosion or insulation damage;

    7.Places without dripping;

    8.The waveform of the supply voltage is similar to the sine wave;

    9.The three-phase supply voltage is approximately symmetrical.
