Teflon plates for electrical insulation (sold in sets of 4)

Set of 4 teflon insulating plates (PTFE) to electrically isolate the transformer from its support and to promote the isolation of the tank. They are placed between the down supports of the electrical transformer (profiles, rollers) and their support (retention tanks, fire dampers, sills,...)

The insulating plates PTFE are placed under the supports of the electrical transformer (wheels, rollers, plates or beams), and the supports of the transformer (concrete still, retention tank, pit or other). The insulating properties of teflon allow the transformer to be electrically insulated from its support, with the characteristics required to promote mass-tank insulation. Sold in sets of 4.

PTFE plates : their excellent insulating and thermal propreties

PTFE plates are excellent electrical insulators and have a high surface resistivity. They are also resistant to arcing and have a very low electrical loss factor.

They are non-combustible and highly resistant to high and low temperatures thanks to a melting point of 327°C. With its non-adhesive and non-wettable surfaces, its wear resistance can be adapted to addition of fillers (glass, carbon or graphite). Thanks to its high chemical resistance to all product, PTFE plates are weather resistant and don't absorb any moisture during rainy periods.

Please choose the appropriate pre-cut plates from the various sizes and ticknesses, taking care to check your avilable bearing surface and the insulation class you require.
