    Short Description:

     

    As we all know, transformer insulation plays a crucial role in ensuring the efficiency and safety of transformers. One interesting insulation material often used in transformer is the OIL DUCT STRIP. GBS OIL DUCT SPACER, which is made of electrical board in the shape of stripe adhered to DDP paper. The strip provides a pathway for oil to flow within the transformer, helping to cool and insulate the components. With proper oil circulation, the oil duct strip helps to maintain consistent temperature levels, which contributes to the overall performance and longevity of the transformer.

     

    Oil duct strip is a specialized insulation material used for the main and cooling ducts in oil-filled power transformers, distribution transformers, and traction transformers. The manufacture of this material adopts unique processing procedures that guarantee high compaction and dimensional stability.

    Application: 

    Mainly applicable to electric cardboard for insulation and its components such as motor, electric

    apparatus, meter, switch, transformer.

     

    Advantages:

    The exceptional mechanical properties of our GBS insulation material provide the required safety in the event of a short circuit. Additionally, its ability to be impregnated with oil strengthens the electromechanical properties, resulting in excellent overall insulation performance for these critical transformer components.

     

    Applying this material will avoid the problem caused by using corrugated cardboard, such as easy deformation, displacement and other weaknesses. It can be combined closely with transformer coil and make coil possessed more excellent mechanical and electrical properties.
