FIELD: electrical engineering.
SUBSTANCE: proposed method for producing spiral skirt 2 for high-voltage insulator 1 allows for manufacture of actually cylindrical backing 3, extruder 10 incorporating extrusion head 11 that governs extrusion direction A, makes use of extruder 10 for extruding insulator skirt 2 and application of the latter onto backing 3 while rotating this backing relative to extrusion head 11. Novelty is that extrusion direction A actually coincides with longitudinal axis of backing 3; the latter is fed through extrusion head 11. Skirt manufactured by this method can be used for high-voltage insulators, high-voltage lightning arresters, or high-voltage cable entries.
EFFECT: ability of producing high-voltage parts having relatively small diameter.
