FLEXEL Autonomy of a “Premium Quality” Heating Cable = Premium quality ( EU sourced ) calibrated resistance wire = Advanced fluoropolymer insulation ( for long life ) = 100% aluminium earth screen ensures full earth protection = Abrasion, cut and crushproof PVC minimises PVC minimises potential damage during installation The Heating Element The Heating Element: is constructed of a metal that has a resistance so that when current flows through it, heat is produced. Flexel only use premier quality copper alloy wire that has been produced by long established quality European manufacturers to ensure consistent calibrated resistance and long life. Our heating elements use an inner insulation of Fluoropolymer, a synthetic material, as it has very good electrical properties and a high melting point which makes it particularly suitable for use in underfloor heating cables. 100% Earth Screen 100% Earth Screen: The Earth Screen on an electric underfloor heating cable is designed to ensure that if the cable is cut or damaged the system automatically trips the RCD turning the system off. The traditional screen design is to place the earth wires in a braided sock format which encompasses the inner heating cores. The improved modern method, used in all Flexel cables, is to envelop the entire cable construction with a layer of
