C'est pour permettre \u00e0 l'usine de fabrication de consid\u00e9rer l'augmentation de la temp\u00e9rature de limite et le minimum de l'air de jeu pour une isolation ext\u00e9rieure. G\u00e9n\u00e9ralement, les fabricants r\u00e9pondent aux exigences de haute altitude des zones en renfor\u00e7ant l'isolation ext\u00e9rieure de coussinets, de l'augmentation de la distance de fuite le long des surfaces et de la clairance \u00e0 la terre, et l'\u00e9largissement de l'air, les espaces entre les bagues de mise \u00e0 la terre des composants.
