Rings & Winding End Structures

Insulation Clamping Rings

Also known as: Transformer Clamping Rings

Insulation clamping rings are used to clamp transformer coils and withstand mechanical forces. They are critical structural components where ring strength and dimensional accuracy influence winding stability.

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

Key functions and options

  • High structural importance
  • Supports coil clamping
  • Custom concentric grooves and openings
  • Drawing-based machining

Typical applications

  • Transformer coil clamping
  • Winding mechanical reinforcement
  • Short-circuit-force support structures
Quotation preparation

Information to include with your RFQ

  • Complete drawing
  • Material and strength requirements
  • Diameter, grooves and holes
  • Quantity

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