    Use the main application

    It is mainly used for testing the insulation level of all kinds of insulating materials, insulating structures and electrical and electric products to withstand power frequency voltage. And partial discharge levels.

    Widely used in electrical manufacturing departments, power operation departments, scientific research units and colleges and universities.


    The performance function


    50-2400kV no local discharge electrical test frame transformer, are the first in China, and excellent performance * stable, through scientific identification, support transformer is mainly used in power transformer manufacturers,

    The main technical performance in the domestic leading position, to reach the international advanced level of similar products.

    1, the complete set of equipment with strong, voltage and capacity series complete, perfect function.

    2. The successful development of epoxy insulation tung without partial discharge ring, to ensure that the local discharge of the system equipment is small, leading the international level;

    3. Adopts high quality DQ120-30 grain oriented silicon steel sheet, 45° fully oblique joint lamination. Waveform domain variability and no-load current of similar products is the smallest in China;

    4, impedance voltage is low, the capacity of the complete set of equipment is less than the national standard;

    5, Adopt automatic control technology and computer (optical fiber) measurement and control, high degree of automation, anti-interference ability;

    6, the use of overvoltage fast electronic protection device, high reliability.
