Vorrichtung zum Schutz bzw. zum Verbinden elektrischer Stromkreise

摘要

The protection or connection device for electrical circuits has a housing comprising at least one opening serving to introduce at least one cable comprising electrical conductors and at least one further opening which enables permanent or detachable connections to be made via the electrical conductors to connection or control conductors. The housing is filled with an insulating encapsulation or embedding compound. According to the invention, the encapsulation or embedding compound for ensuring a high temperature stability and, consequently, short-circuit immunity even at extremely high temperatures but nevertheless accompanied by high insulation resistance is composed of a binder matrix which comprises, as main component, a cured mixture of a) finely divided SiO2 and b) at least partly water-soluble silicates
