Le matériau de la couche de gaine (1) est un matériau écologique en polyoléfines sans halogènes à faible émission de fumées ayant une résistance aux hautes températures jusqu'à 110 °C. Le matériau de la couche d'isolation (2) est un matériau d'isolation en polyéthylène réticulé ayant également une résistance aux hautes températures jusqu'à 110 °C. La couche en ruban de mica (3) est fabriquée en enroulant deux couches superposées d'un ruban de mica de type phlogopite calciné. L'organe conducteur (4) est fabriqué en torsadant plusieurs fils de cuivre nus recuits. Le câble de puissance est résistant au feu jusqu'à 1050 °C, extrêmement proche du point de fusion du cuivre. Le câble de puissance est capable d'un fonctionnement efficace même lors d'un incendie important dont la température est comprise entre 950 °C et le point de fusion du cuivre, améliorant ainsi significativement la sécurité durant l'usage, et assurant la sécurité des personnes.
