Abstract

The invention relates to a surge arrester comprising a stack of arrester elements (1), for example of zinc oxide, arranged between two end electrodes (2) in an elongated insulating casing (3) of polymeric material, for example EPDM rubber. To mechanically reinforce the arrester, a tube (4) of fibre-reinforced plastic is arranged between the stack of arrester elements (1) and the polymer insulator (3). This tube (4) is manufactured by profile drawing, so-called pultrusion, whereby all reinforcement fibres extend in the axial direction of the tube. This gives the tube (4) a high tensile strength while at the same time the strength in the radial direction is relatively low. This is advantageous in the event of an arrester failure with an internal short circuit, since the tube will then easily crack up and provide a rapid pressure relief without any explosion hazard.
