Transformers

'DyBond' products are flexible insulation materials coated with class B resin (not fully polymerised) on one or both sides. This material can also be resin coated (in thermal class H) over the entire surface or spotted with resin. DyBond tapes are used as electrical insulators...

DYFILM® PET film

DyFilm® is a polyester film is obtained by condensation between ethylene glycol and terephthalic acid. Due to its excellent electrical, chemical and physical properties, DyFilm® is widely accepted and required in all markets, industries and applications where it is required...

DyFlex® is an insulation product obtained by combining a non-woven polyester-based non-woven fabric with a polyester-based PET film. The non-woven fabric is made of highly calendered short fibres, laminated onto PET film with the appropriate adhesive substances. The laminate is then...

Coveme yTerm® is an insulation product resulting from the combination of Nomex® aramid paper and polyester film. The layers of Nomex are bonded to the polyester film with suitable adhesives. DyTerm® laminates are suitable for use in electrical equipment at the following operating temperatures...

NOMEX® aramid paper

Nomex aramid paper – is mainly used as a dielectric insulator in systems operating at high ambient temperatures. Consumption charts for insulation materials show that an insulation system based on 'Nomex' paper has a service life of more than 20,000 man-hours in...
