The invention relates to bases for cutout circuits and to a method for the production thereof. Said circuits are used in medium-voltage distribution lines to protect the lines and are manufactured in such a way that connection of the supporting arm to the insulator is performed in a safe and reliable manner due to the fact that it has a rigid insulating core (1) on which the support arm (4) is effectively held either by a piece (6), stuck thereto or by configuring the core (1) and the arm (4) as a single piece. The parts (3) enabling connection of the insulator to the fuse holder element (5) are fixed on the ends of the core (1), wherein the entire assembly is insulated by an injection-molded polymeric material (2), which makes the cutout circuit safe, resistant and light. |
