Abstract: It provides a surge arrester (1) and its manufacturing method. The surge arrestor (1) includes an active part (10) extending along a longitudinal direction (14) of the surge arrester (1), a first electrode (11) having a first interlocking part (110), being arranged to rest against a first end (100) of the active part (10), a second electrode (12) resting against a second end (101) of the active part (10), wherein the second end (101) opposes the first end (100) in the longitudinal direction (14) of the surge arrester (1), a flexible insulating housing (13), being arranged around an assembly of the first electrode (11), the active part (10) and the second electrode (12), and a second interlocking part (132) formed on an inner surface of the flexible insulating housing (13). The first interlocking part (110) of the first electrode (11) is arranged to fit with the second interlocking part (132) of the flexible insulating housing (13) for preventing relative movement of the first electrode (11) and the flexible insulating housing (13) in the longitudinal direction (14) of the surge arrester (1). The flexible insulating housing (13) includes: a support member (130) mechanically connecting and supporting the assembly of the first electrode (11), the active part (10) and the second electrode (12), which has a plurality of supporting elements (130a,130b) being arranged parallel to the longitudinal direction (14) of the surge arrester (1) and being arranged laterally at sides of the assembly of the first electrode (11), the active part (10) and the second electrode (12), and an insulating expandable part (131) with a plurality of sheds extending outwards, being moulded around the support member (130) and being spaced apart from the assembly of the first electrode (11), the active part (10) and the second electrode (12). Because the support elements (130a,130b) are mechanically connected by the flexible insulating housing (13), by exerting outwards radial force on the flexible insulating housing (13), the cross- section of its inner space is enlarged, thus making it easier to insert the assembly of the first electrode (11), the active part (10) and the second electrode (12) into the flexible insulating housing (13). Besides, the interlocking mechanism ay prevent an undesirable relative movement between the electrode (11,12) and the flexible insulating housing (13) in the longitudinal direction (14).

Abstract: Der Hüllkörper (1) dient dem Umhüllen des Endes, einer Abzweigung oder einer Verbindungsstelle eines Hochspannungskabels. Er weist ein Element (3) mit einer nichtlinearen Strom-Spannungs-Kennlinie auf, welches dem Steuern des elektrischen Feldes im Hüllbereich dient. Das Feldsteuerungselement (3) enthält ein Polymer und einen in das Polymer eingebetteten und Mikrovaristoren enthaltenden Füllstoff sowie mindestens einen längs einer Achse (2) erstreckten und flächenhaft ausgeführten Hohlkörperabschnitt mit einer durch Verformen des Hüllkörpers (1) an eine Aussenfläche des Kabels führbaren axialsymmetrischen Innenfläche. Um eine gute Feldsteuerung auch bei Kabeln zu gewährleisten, die mit hohen Spannungen betrieben werden, ist die Innenfläche des Hohlkörperabschnitts abweichend von der Aussenfläche des Kabels ausgebildet und zwar derart, dass durch Verändern der Anzahl der Mikrovaristoren pro Flächeneinheit infolge Dehnung und/oder Schrumpfung des Hohlkörperabschnitts nach dem Verformen die Feldsteuerung im Hüllbereich erreicht ist.

Abstract: The invention relates to a sleeve (1) which surrounds the end, a branch, or a joint of a high-voltage cable. Said sleeve comprises an element (3) with a non-linear ampere-volt characteristic, which controls the electric field in the vicinity of the sleeve. The field control element (3) comprises a polymer and a filler that is embedded in said polymer and contains microvaristors, in addition to a flat hollow-bodied section that extends along one axis (2), with an axially symmetrical internal surface that can be guided onto an external surface of the cable by deforming the sleeve (1). The aim of the invention is to guarantee excellent field control, even for cables operating at high voltages. To achieve this, the internal surface of the hollow-bodied section is configured differently from the external surface of the cable, in such a way that the field control in the vicinity of the sleeve is achieved by modifying the number of microvaristors per unit of surface area by means of the extension and/or shrinkage of the hollow-bodied section after deformation.
