    Abstract: A surge arrester (100) and a method for manufacturing the surge arrester (100), the surge arrester (100) comprises a preassembled active part (110) extending in a longitudinal direction (Y), and a separately produced flexible housing (120) defining a bore (121) in the longitudinal direction (Y) and having an opening at an end surface (126) of the flexible housing (120), the flexible housing (120) is arranged surrounding the active part (110) via the bore (121) and in contact with the active part (110), the contact causes a deformation of the flexible housing (120) in a circumferential direction (C), and the deformation generates a pressure applied on the active part (110) along a radial direction (R).

    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).
