Automatic equal division and reference-line marking for transformer insulation end rings

Large transformer insulation end rings often require many evenly spaced reference positions. Manual circumference measurement takes time and can accumulate angular error.The TRANFOVIA End Ring Equal Division Draw Line Machine automates equal division and reference-line marking for transformer insulation end rings. Operators enter the number of divisions together with the end ring inner diameter and outer diameter through the touch screen. The machine then calculates the equal positions and marks the ring automatically, reducing repeated manual measuring and providing consistent references for later insulation assembly work.

Equipment Application

The machine is typically used after an insulation end ring has been cut or machined and before later layout or assembly operations. The end ring is placed on the circular worktable, the division quantity and ring dimensions are entered, and the marking head draws the reference lines automatically. It is suitable for manufacturers processing medium and large end rings that need a repeatable alternative to manual line drawing.

Main Features

  • Touch-Screen Parameter Input

The operator enters the number of equal divisions together with the end ring ID and OD, reducing repeated manual calculation and measurement.

  • ±0.02° Equal-Division Accuracy

The specified drawn-line angular accuracy is ±0.02°, supporting projects that require evenly distributed reference positions around the end ring.

  • Approximately 3 Minutes per Workpiece

The stated working efficiency is approximately three minutes per piece. Loading, setup and final inspection time should be considered separately.

  • Φ500-Φ3200 mm ID Adjustment Range

The adjustable ID range covers a broad selection of transformer insulation end rings. The required OD should still be supplied for technical confirmation.

  • Adjustable Marking Head

The marking-head height can be adjusted from 10 to 80 mm to suit different end-ring workpiece heights.

  • Workshop-Friendly Power Connection

The machine uses an AC 220 V, 50 Hz plug-connected power supply, allowing practical repositioning within the insulation workshop.

FAQ

  1. What is the machine used for?

It divides transformer insulation end rings into equal sections and draws reference lines automatically.

  1. Which parameters does the operator enter?

The operator enters the required division number and the end ring ID and OD through the touch screen.

  1. What end ring sizes can be processed?

The specified ID adjustment range is Φ500-Φ3200 mm. The required OD and workpiece weight should be supplied for confirmation.

  1. What marking accuracy is specified?

The specified equal-division or drawn-line angular accuracy is ±0.02°, with a line width of no more than 1 mm.

  1. How long does one marking cycle take?

The stated working efficiency is approximately three minutes per piece, excluding loading, setup and inspection.

  1. Does the machine cut or mill the end ring?

No. It is intended for equal division and line marking. Ring cutting and groove machining require separate equipment.
