    1) Low no-load loss

    1. The high-quality silicon steel sheet is adopted.

    2. Wound iron core fully utilizes orientation of the silicon steel sheet. The magnetic property is recovered through annealing process, so that the no-load loss is reduced by 20%~35%.

    2) Low noise

    The noise is from the iron core, and is transferred to the surrounding through the shell.

    Measures for noise reduction: 1. reduce the noise source, and adopt the seamless wound iron core, compact structure, small magnetostriction and low noise.

    2. The connecting position is added with silica gel plate, which cuts off the noise spreading approach.

    3) Light weight and small volume.

    4) It has explosion-proof and damp-proof performance.

    5) Energy conservation and environmental protection

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

    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 foreign similar products, which saves the energy, and lowers noise.
