Transformer Tapes

Power transformer tapes are mainly used in core, layer and final insulation of coils and transformers, phase and coil-end insulation. We can also find them in the sealing connection leads for final insulation, strengthening of edges in slot insulation and for slot insulation in general. Our power transformer tapes contain a variety materials for different purpose, such as fibre reinforced transformer tape, oil resistance blue self-adhesive tape, nomex paper insultion tape, double-sides tape with heat resistance, amorphous metal transformer tape. Oil-resistant tapes can resistant against most transformer oils including chlorinated oils. “transformer oil miscibility test” by the third party is very good. tapes are suitable for insulation wrapping of oil filled power transformer with little affects the dielectric loss and total hydrocarbon of transformer oil, and no hydrogen evolution.

Fibre Reinforced Transformer Tape

The fiber tape with oil resistance one-side adhesive tape is made of reinforced resin-type fiber composite and electrical polyester film, after special treatment of solvent resistance and high temperature resistance, has the characteristics of strong viscosity, voltage resistance, oil immersion resistance and chemical corrosion resistance.

Oil Resistance Blue Self-adhesive Tape

the oil resistance blue tape is made of electrical polyester film with thermosetting polyacrylate adhesive. It has the characteristics of strong viscosity, high dielectric strength, oil immersion resistance and class B of heat resistance. The oil resistance blue tape widely used in the manufacture of oil filled transformers, especially for sealing of inner coil, phase and coil-end insulation.

Nomex Paper Insulation Tape

Nomex paper insulation tape is made of high temperature resistant polyamide fiber paper (which is recognized as a high-quality electrical insulation material globally) coated with high-performance adhesive. It has the characteristics of high temperature resistance, flame retardant, voltage resistance, chemical solvent resistance, flexibility and wear resistance.

Heat Resistance Double-sided Insulating Tape

The heat resistance double-sides insulating tape has strong persistence adhesion, high initial tack,  good weather resistance and voltage resistance. large amount of coating guarantees good adhesion to rough surface, it can firmly adhere laminated cardboard, dispensing paper, electrical composite film, knitted polyester tape and other insulation materials for transformers for a long time. Its short-term temperature resistance can reach 200 degrees.

Amorphous Metal Transformer Tape

The transparent tape for amorphous alloy transformer with oil resistance is made of electrical polyester film, after special treatment of solvent resistance and high temperature resistance, has the characteristics of strong viscosity, high voltage resistance, oil immersion resistance and chemical corrosion resistance. It hardly affects the dielectric loss and total hydrocarbon of transformer oil, and has no hydrogen evolution.
