TFT2 - Triplex 2mils (50micron)

TFT2 is a three-ply composite of TUFQUIN 2mils (0,05mm) mineral insulation paper bonded to both sides of polyester film with the means of a high quality resin. TFT laminates provide excellent value in use as they exhibit a balanced blend of electrical, physical, and thermal capabilities on a cost effective basis.

With the thermally stable outer layers of TUFQUIN the composite is certified by UL as component for electrical insulation systems in CLASS N 200°C. Additionally the inorganic content in TUFQUIN provides excellent resistance to hot cut-through in high temperature applications. The high thermal conductivity of TUFQUIN/film laminates promotes cooler running equipment, leading to longer insulation life, better reliability, and more efficient use of power. TFT laminates are non-hygroscopic and exhibit low moisture absorption characteristics, thus reducing the need for extended drying cycles prior to varnishing or encapsulation.

Due to the central polyester-ply TFT has a good memory shape and snapback. TFT laminates exhibit also excellent resistance to tear initiation and tear propagation in both the machine direction and across the machine direction. The good elongation characteristics let TFT laminates absorb the stress of heavy duty winding applications.
TufQUIN TFT laminate insulations are designed for use as slot cell, phase and wedge insulation for motors and generators through Class 200°C(N). They may also be used as layer and ground insulation in dry-type transformers Class 200°C(N).
