Bushing Winding Machine

Bushing winding machine

This machine is used to wind condenser core for OIP bushings with one un-coiler (web).

 The maximum 3500mm paper can be used as un-coiler.

 Decoiler is controlled by magnetic brake with a feedback of load cell.

 The central part of machine is consisting of solid steel frame on which bottom heated rollers, top pressure roller assembly, Cutter assembly are mounted.

 Bottom heated rollers are heated with Thermic oil. Temperature of the heated oil will be 110 deg.

 Top pressure roller heating is optional.

 The cutters are cutting the paper in right length. The paper ends are cut in straight, in steps or cone. Step cutting and cone cutting is possible on both sides.

 The reference line of the machine is always the Oil side of the bushing.

 Top pressure roller movement is controlled by hydraulic system. The specific pressing force is adjustable in steps and remains constant throughout the winding.

 One foil guide shows the exact position of foil insertion. Second side laser foil guide is optional.

 Accurate diameter measurement guarantees correct insertion of aluminum foil.

 Separate Industry standard control cabinets for controller+ servo drives, VFDs & IR heater (optional)

 Depending on customer`s requirement machine can be equipped with optional features

o Infra red heating system to dry paper during winding, which reduces the time for drying in autoclave.

o Laser guide for another end of foil, to ensure correct foil insertion.

o Second Decoiler unit.

o Top pressure roller heating

Bushing winders – or: winding machines for condenser bushings – are used to wind insulating bodies for Resin Bonded Paper  or Oil Impregnated Paper condenser bushings from kraft or crepe paper and aluminum foil.
