Abstract

La presente invención se refiere a una cubierta para un dispositivo eléctrico, la cual comprende: una envoltura exterior; una pared interior hecha de un material eléctricamente no conductor impermeable a la humedad, y que protege a dicha envoltura exterior contra el rompimiento de la misma por el choque térmico causado por el calor producido dentro de la cubierta; y un elemento de ancla para fijar la cubierta sobre un soporte mecánico; dicha envoltura es hecha de un material aislante capaz de soportar una alta tensión mecánica, y es moldeado sobre dicha pared interior y alrededor de dicho elemento de ancla, por lo que dicha pared interior es integrada con dicha envoltura, y dicho elemento de ancla es unido fijamente al material aislante que constituye la envoltura exterior.
