摘要： The invention relates to a bobbin for an electrical coil comprising an plastic core made of an electrically insulating plastic material and to a polyamide composition that can be used as the electrically insulating plastic material in the bobbin, comprising a semi-crystalline semi-aromatic polyamide comprising units derived from aliphatic diamines consisting of a mixture of 10-70 mole % of a short chain aliphatic diamine with 2-5 C atoms and 30-90 mole % of a long chain aliphatic diamine with at least 6 C atoms; and units derived from dicarboxylic acids consisting of a mixture of 5-65 mole % aliphatic dicarboxylic acid and 35-95 mole % aromatic dicarboxylic acid comprising terephthalic acid, and wherein the combined molar amount of terephthalic acid and the long chain aliphatic diamine is at least 60 mole %, relative to the total molar amount of the dicarboxylic acids and diamines. The invention also relates to an electrical coil comprising the bobbin and an electrically conductive winding around the core of the bobbin.
