<p>An open-wire insulator and a method for the production thereof. For the avoidance of the problems resulting from the connection between the annular flanges and a bar of reinforced plastic forming the core in previously known structures, the insulator according to the invention comprises an open-wire insulator comprising a core (3) of cast resin and an outer covering formed by plate-like flanges (1) piled one upon another and distance sleeves (2), said covering surrounding the core portion (3) formed of a cast resin capable of reacting with the covering essentially on all sides except the end faces and in which insulator the core is reinforced with fiber glass.</p> |
