Spacers, Strips & Oil Duct Components

Insulation Strips

Also known as: Winding Strips, Oil Duct Strips

Insulation strips are installed inside transformer windings to provide support and form axial cooling oil ducts. Common profiles include rectangular, T-shaped, dovetail and customer-specific strips.

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

Key functions and options

  • Supports axial oil-duct formation
  • Multiple standard and custom profiles
  • Improves winding stability
  • Drawing-based lengths and tolerances

Typical applications

  • Axial cooling oil ducts
  • Winding support
  • Transformer insulation structures
Quotation preparation

Information to include with your RFQ
