In Dry Cast resin transformers, our insulating tubing made of DMD, Nomex® and Mylar is used to cover the tie rods.

It is supplied with high wall thickness to ensure perfect insulation and guarantee mechanical rigidity.

In oil type transformers, crepe paper or Nomex tubing is used, as it is softer, more easily “shrinkable” and oil-impregnated; in this application it is used to cover the primary/secondary connection cables.
