    Transformer Test

    Each transformer must be tested before leaving the factory. The routine tests include

    •Ratio, Polarity, and Phase Relation

    •Resistance

    •Applied Potential

    •Induced Potential

    •Loss Test

    •Leak Test

    •Operation tests of all devices: All electrical and electro-mechanical devices shall be operated both in auto and manual mode for proper sequencing/staging and function.

    If you need special tests like short circuits, Daelim Transformer can do that too.

    Daelim Substation Transformer Packaging

    Daelim transformers are usually packed in two ways, one is wooden box packing, and the other is wooden pallet packing. It is mainly based on whether the shipping is FCL or LCL.

    The whole container transportation adopts the packaging method of wooden pallets, which can save costs while ensuring safety during transportation.

    The transformers are packed in wooden boxes when they are transported in LCL because the wooden boxes are sufficiently strong and stable. The safety of the transformer can be guaranteed on the bumpy road.

    substation transformer package
    Daelim Factory

    Daelim will send a transformer report to the customer before the transformer is packaged and shipped. All physical and electrical properties of the transformer can meet or exceed the standard before delivery.

    The Daelim factory is located in the hometown of transformers, Haian, Jiangsu, where there is a complete supply chain of transformers and skilled transformer workers. It is only 200km away from Shanghai port.

    Therefore, Daelim has the ability to deliver fast. You can check the progress of your transformer order and production link on the daelim website at any time.

    Daelim also supplies three-phase pad-mounted transformers, single-phase pad-mounted transformers, Hv power transformers, pole mounted single phase transformers, and dry-type transformers.
