Rings & Winding End Structures

Transformer End Rings

Also known as: Insulation End Rings, Winding End Rings

Transformer end rings form part of the main insulation structure between windings and the core yoke. They support end coils, provide end insulation and help distribute axial clamping force.

Dimensions, materials, tolerances and testing requirements are confirmed according to customer drawings and order specifications.

Key functions and options

  • Supports winding ends
  • Helps distribute axial pressure
  • Reduces local stress concentration
  • Custom diameters and segmentation

Typical applications

  • Upper and lower winding ends
  • Core-yoke insulation interfaces
  • Axial clamping structures
Quotation preparation

Information to include with your RFQ

  • Inner and outer diameter
  • Thickness and segmentation
  • Material and drawing
  • Quantity

For custom parts, a dimensioned drawing is the most reliable starting point. Drawings can be emailed to sales@boreviax.com.
