Transformer Coil Wire winding machine of the WHC series with strip insulation for coils up to 600kv

Transformer Coil Wire winding machine of the WHC series with strip insulation for coils up to 600kva WHC series for HV-coils with automatic cutting and re-attachment of strip insulation. Winding without manual intervention. On WHC winding machines high voltage coils for small distribution transformers can be wound. Simultaneously to the winding of the conductor, the layer insulation is built up automatically with Two insulation strips. The layer insulation can be built up either conically or cylindrically. The insulation strip is automatically fed-in and fixed. If needed the insulation strip is automatically separated and re-attached after the layer is built up. This allows automatic winding from coil start to cooling channel or lead out without any manual interference by the operator. A PC control system pre-calculates and executes all necessary stop points. Strip insulation technology Strip insulation allows a conical build-up of the layer insulation. The end filler is automatically filled up with the same insulation strip(s).The insulation strip is wound with constant, dancer controlled tension which guarantees a high filling factor and small radial tolerances. It is possible to program each layer insulation different which is needed for the high voltage impacts. Wire guiding unit with dancer-regulated brake system A dancer system regulates the motor-powered brake rollers and keeps the pre-selected wire tension constant even at oval or rectangular coil shapes. This ensures perfect layer build up at high winding speeds. The required wire tension can be adjusted on the control panel without any mechanical intervention. Automatic insulation strip cutting and reattachment system The insulation strip moves ahead of the wire to build up the layer insulation and then automatically builds up the required endfi ller at the layer end. If the strip insulation must be cut and reattached no stop is required due to the automatic cutting and reattachment system. Flattening unit for round wire With the proven fl attening unit, the round enamel-insulated wire can be rolled fl at to an adjustable height.The advantage of fl attening round wire is a higher fi lling factor which results in smaller coil dimensions and reduction of the conductor material, core material and tank volume. This leads to signifi cant savings of transformer manufacturing costs.
