Dovetail Spacers
Dovetail spacers lock into dovetail strips to form the radial cooling ducts of a transformer winding. We make them from pressboard with a precise dovetail profile so they sit firmly and keep duct spacing even along the whole winding height.

Common questions
What is a dovetail spacer used for?
Dovetail spacers slot into dovetail strips to form the radial cooling ducts between winding discs. They keep the duct spacing even and hold their position when the winding is clamped.
Can you supply matching dovetail strips?
Yes. We cut dovetail strips to the same profile as the spacers so the two parts fit together correctly.
Can the profile be made to my drawing?
Yes. We make standard dovetail profiles and custom profiles to drawing.
