Core and Coil Assembly:


*Internal part assembly :

This process is carried out in production line and tested after each step. First, the core is carried to the mouting station, and then the HV and LV coils are mounted and centered. After that, the upper yoke is stacked and the core-coil clamping devices are fixed.

       The HV terminal are insulated with special crimping paper tubes. The HV terminal positions are fixed by pressboard panel. The LV terminal are fixed to LV bushings by bolts.
