Glass-fibre-profiles connected with insulating tapes.


Glass-fibre-duct-spacing-mats are a cost effective cooling channel solutions with free selectable / adjustable distances of single profiles. Also different profile-shapes can be used in one mat.


Glass-fibre-duct-spacing-mats are used in transformer and coils with cooling channels. They can be used in automated winding processes.
