Adhesive tapes for oil – filled transformers  - With more than 20 years experience in electrical insulation tapes products, Von Roll is offering the full range of adhesive tapes which are essential for oil - filled transformer manufacturing. The offered products are suitable for all applications in the construction of windings.

Adhesive tape Intertape 4238  - High tensile strength, conformable backing with aggressive adhesive for a variety of heavy duty insulating and holding applications. This tape is very resistant to chemicals, solvents and ageing, and offers high dielectric strength and insulation resistance.

Adhesive tape 51600 PV3 - Is a woven polyester backing system that provides a high tensile strength. The aggressive adhesive makes this tape ready for a variety of heavy duty insulating and holding applications. Excellent solvent and oil resistance.

Adhesive tape 52402PV3 - Paper/Glass filament reinforced tape. It is expressely engineered as a construction tape for use in the manufacture of oil - filled distribution and power transformers. The paper backing allows the oil absorbtion to minimize the air entrapment.

Adhesive tape PG22 - Paper tape with excellent adhesion to and transfer free removal from a variety of prepared aluminum surfaces. Suitable to get clean paint break lines. A pressure - sensitive masking tape designed, primarily for the aircraft industry where resistance to high solvent polyurethane based paints is a necessity.
