<p>The invention relates to an insulating board (11) between the winding and core sheet pack of a ballast or transformer, said board being intended to be placed between the inner gable surface (4) of a winding loop (2) and the gable of a core sheet pack extending through the winding loop opening (5). The insulating board is provided with hinge members (13) to carry outer side flaps (12), whose free ends are fitted with catching claws (15) which can be brought into engagement with counter-catch means (14) mounted on the insulating board. Mounted in its position, said insulating board, together with its outer side flaps, surrounds the end sections of surface insulations (3) and holds said surface insulations fixed in position without requiring the use of binding tapes.</p> |
