Electrostatic Ring Wrapping Machine for Transformer insulating material processing

Precision-engineered for transformer static shield insulation, this Electrostatic Ring Wrapping Machine applies uniform cable paper and wrinkle paper wraps to both flat and inclined electrostatic plates. Capable of processing rings from Φ750mm to Φ3000mm with axial heights of 15–250mm, it uses a ½-lap bandaging method to wrap up to three plates simultaneously at maximum diameter. Adjustable tape tension (60–120N) and a versatile paper reel system (75mm inner shaft, 300mm outer shaft) ensure consistent insulation quality. The robust semi-circular frame, guide rails, and automated paper tape feed minimize manual handling, making it ideal for high-voltage transformer insulation production.

Description

1. Core Features & Advantages

① Versatile Electrostatic Plate Wrapping

Specifically designed for insulating paper wrapping of inclined and flat electrostatic plates (static shields) in transformers. Ensures uniform dielectric coverage for high-voltage components.

② Wide Size Range

  • Inner diameter: min. Φ750mm to max. Φ3000mm

  • Amplitude: 15mm – 300mm

  • Axial height: min. 15mm, max. 250mm

③ Simultaneous 3-Plate Wrapping

Utilizes a half-lap (½ wrap) method to bind up to 3 plates at once when processing the largest Φ3000mm diameter plates, significantly boosting throughput.

④ Precise Tape Tension Control

Adjustable insulating tape tension from 60–120N guarantees tight, even wraps without creases or gaps, critical for insulation integrity.

⑤ Multi-Material & Size Compatibility

Wraps cable paper and wrinkle paper. Paper reel specs: 75mm inner shaft diameter, 300mm outer shaft diameter. Compatible tape widths: 19mm & 25mm cable tape, 25mm wrinkle paper.

⑥ Robust & Automated Design

Blue semi-circular frame with yellow fixtures, silver guide rods, motorized rollers, and left-side reel stand for continuous paper feed. Reduces manual labor and ensures repeatable wrap quality.
