ABSTRACT:
The invention relates to line insulators made of organic material. Such an insulator comprises a bar (7) of high tensile strength, a protective sheath (8) made of an elastomer material, a plurality of fins (4) and an anchor fitting (2) at each end. In accordance with the invention, at least one inner part of the insulator is semiconductive along the whole length which separates the anchor fittings (2); this part may be constituted either by the sheath (8) itself or by the bar (7) and the bedding material in said fittings. Application, in particular, to line insulators intended for use in highly polluted zones.
