PCT No. PCT/SE94/00097 Sec. 371 Date Sep. 11, 1995 Sec. 102(e) Date Sep. 11, 1995 PCT Filed Feb. 8, 1994 PCT Pub. No. WO94/22150 PCT Pub. Date Sep. 29, 1994A surge arrester with an elongated polymer housing (1) includes a stack of arrester elements (2), for example of zinc oxide. To limit the radial voltage stress which may arise in the polymer material upon pollution, the polymer housing (1) is provided on the outside with field-equalizing control electrodes (6) in the form of bands or rings of metal at regular distances along the arrester. The control electrodes (6) are electrically connected to the ZnO stack (2, 3) inside the housing (1).
