Top-of-the-range TEFZEL 18 AWG electrical wire, used in aeronautics and racing vehicles.
Designed to offer maximum conductivity, extreme thermal resistance and exceptional durability in demanding environments.
This wire is used in aviation, motor racing and top-of-the-range electrical preparations. It combines lightness, chemical resistance and exceptional thermal stability thanks to its ETFE (Tefzel) insulation.
Its silver-plated copper design guarantees excellent conductivity while limiting corrosion and electrical losses.
Its thin but robust insulation saves weight and makes bundles easier to handle, ideal for compact installations or those subject to strong vibrations.
Tefzel wire cross-section 1mm2 = 10 amperes
Tip: To power appliances that require more current, we recommend multiplying the wire by 2 or 3.
The advantages of Tefzel wire:
-
TEFZEL (ETFE) insulation: resistant to heat, fuels, oils and solvents
