    Scope:


    1. With high requirement on the reliability of power supply;

     2. With bigger voltage fluctuation;

     3. Need to adjust voltage frequently everyday.


    Product Description:


    on load tap changer offered, custom-made designs, rich experience in transformer production,

    various Voltage & Power available


    The differences between OLTC transformer and General no load tap changer transformer:

    1. The biggest advantage of OLTC transformer is can adjust voltage on load under the condition

    of without a power outage; But general transformer need to cut the power first and adjust the voltage

    manually.

       2. The price of OLTC transformer will expensive than the normal one, the installation cost will get higher

    also. If it occurs failure, the cost of maintenance will higher as well as.

      3. OLTC transformer is appropriate for the area which with unstable voltage supply or loading, but with

    high requirement for the voltage and need to adjust the voltage frequently. That these users should

    choose OLTC transformer.


    4. If the production process is continuous, but it has deviation with the voltage, that choose OLTC

    transformer will improve the reliability of power supply.


    5. No need to cut power or test when the OLTC transformer running, but NO load tap changer

    transformer after adjusts tap changer manually, needs to do " Transformer dc resistance test ".

    Then it need professional person and instrument to achieve this job. It will increase management

    cost and employment.


    PS: the weight and dimension just for reference, please in kind prevail.
