Trieda izol\u00e1cie definuje maxim\u00e1lnu povolen\u00fa teplotu vinutia. Trieda B = 130 \u00b0C, trieda F = 155 \u00b0C, trieda H = 180 \u00b0C.

T\u00e1to tepeln\u00e1 rezerva 35 K dramaticky predl\u017euje \u017eivotnos\u0165 izol\u00e1cie: \u017eivotnos\u0165 izol\u00e1cie sa zhruba zdvojn\u00e1sob\u00ed pri ka\u017edom zn\u00ed\u017een\u00ed prev\u00e1dzkovej teploty o 10 K (Montsingerovo pravidlo).
