ABSTRACT:
A method of providing a shed (2) for a high-voltage insulator (1) includes providing a substantially tubular substrate (3), providing an extruder (10) having an extruder head (11) defining an extrusion direction (A), using the extruder (10) to extrude the shed (2) and applying the shed (2) on the substrate (3) while rotating the substrate relative to the extruder head (11). The extrusion direction (A) substantially coincides with the longitudinal axis of the substrate (3), and the substrate (3) is fed through the extruder head (11).
