Beschreibung
Zusammenfassung:	Electrical insulation system based on poly(butylene terephthalate), optionally containing further additives, wherein said poly(butylene terephthalate) (i) has been obtained by polymerizing a cyclic low molecular weight oligomeric poly(butylene terephthalate) resin, contains (ii) at least one filler material or a mixture of such filler materials in an amount of up to 85% by weight, and (iii) at least one hydrophobic compound or a mixture of such compounds, preferably an organopolysiloxane, in an amount of 0.1% to 10% by weight, calculated to the weight of the insulation system; method of making said electrical insulation systems.
