The TRANFOVIA Transformer Electrostatic Ring Wrapping Machine is designed for insulation-paper wrapping of flat and oblique electrostatic rings used in transformer manufacturing. The machine accommodates electrostatic rings from a minimum inner diameter of 500 mm up to a maximum outer diameter of 3000 mm, with axial heights from 15 to 150 mm and radial dimensions from 20 to 200 mm.
The specified wrapping materials are cable paper and crepe (wrinkled) paper. Cable paper can be supplied in 19 mm or 25 mm width, while the specified crepe-paper width is 25 mm. Paper-tape tension is set within a 50-100 N range.
This machine is used in transformer insulation workshops for electrostatic ring insulation wrapping of flat or oblique rings with cable paper or crepe paper before subsequent transformer assembly. It is intended for ring-shaped workpieces rather than straight lead wires or cylindrical equalizing pipes, so the working range is defined by ring inner diameter, outer diameter, axial height and radial dimension. Within a transformer insulation processing system, it serves as the dedicated electrostatic-ring paper-wrapping station.
The machine is dedicated to electrostatic-ring wrapping, keeping the page and equipment selection separate from lead-wire and equalizing-pipe wrapping equipment.
The specified range covers a minimum ring ID of 500 mm and a maximum OD of 3000 mm, with axial height from 15 to 150 mm and radial dimension from 20 to 200 mm.
The listed wrapping materials are cable paper and crepe paper. Cable paper widths are 19 mm and 25 mm; crepe paper width is 25 mm.
Paper-tape tension is adjustable within the specified 50-100 N range, allowing the process setting to be matched to the ring and insulation paper requirement.
The specified paper reel uses a 75 mm inner diameter and a 300 mm outer diameter, giving buyers a clear consumable-interface requirement before ordering.
The specified wrapping method is half-stack type. Project details should confirm the required overlap arrangement and paper specification before production approval.

Choose the Electrostatic Ring Wrapping Machine when the workpiece is a flat or inclined transformer electrostatic ring. Selection should be based on the ring inner diameter, outer diameter, axial height, radial dimension, insulation paper type and required tape tension. It is suitable for customers who need consistent paper wrapping around large electrostatic rings used in transformer insulation structures.
Choose the Transformer Lead Wire Taping Machine when the workpiece is a transformer lead or cable. The main selection factors are lead or cable diameter, required taping length, taping pitch, number of wrapping layers, taping speed and lead rotation speed. It is more suitable for continuous insulation wrapping of transformer leads where the wrapping parameters need to be preset and controlled during production.
It is used to wrap flat and oblique transformer electrostatic rings with insulation paper. The listed wrapping materials are cable paper and crepe paper.
The specified range starts from a 500 mm minimum inner diameter and extends to a 3000 mm maximum outer diameter. Axial height is 15-150 mm and radial dimension is 20-200 mm.
The listed cable paper widths are 19 mm and 25 mm. The listed crepe-paper width is 25 mm.
The specified paper-tape tension range is 50-100 N.
No. This machine is designed around ring-shaped electrostatic components. Lead-wire taping machines process straight or supported lead wires and use different selection parameters.
