A mounting device for mounting a line surge arrester on a power tower includes a base having at least one fastening structure for fastening to a tower-side component, and a joint unit for positioning the line surge arrester. The joint unit has a joint for pivoting the line surge arrester about a joint axis. At least one position is a mounting position and at least one other position is a working position of the line surge arrester. The mounting device furthermore has parts of a drive mechanism. The parts are permanently connected to the base and/or to the joint, for driving the pivoting of the line surge arrester. A line surge arrester unit includes a line surge arrester and the mounting device. A method provides for mounting a line surge arrester on a power tower.

An insulator arrangement for an overhead line includes a suspension insulator for securing an overhead line to a tower and a line arrester arrangement which is disposed electrically parallel to the suspension insulator. The line arrester arrangement has a surge arrester, which is electrically connected to ground or earth potential, and a spark gap, which is connected to the surge arrester in series and which includes a first spark electrode connected to the overhead line and a second spark electrode connected to the surge arrester. The line arrester arrangement has an assembly or mounting insulator which can be secured to the overhead line. The first spark electrode is secured to a first securing device at a first end of the assembly or mounting insulator, and the second spark electrode is secured to a second securing device at a second end of the assembly or mounting insulator.

Overvoltage arresters are used to protect against overvoltages in electrical energy transmission systems. An overvoltage arrester has a discharge column which extends along a longitudinal axis and is clamped in between end fittings by a plurality of tensile elements which radially surround the discharge column and are secured in the end fittings. At least one of the end fittings has a first thread for attaching a connecting bolt. Furthermore, the end fitting has a fitting body with a second thread for receiving a pressure screw for generating an axial force on the discharge column. Accordingly the first and second threads overlap along an axial section.

A hanging arrangement for items of electrical operating equipment includes an upper fastener for suspending the hanging arrangement, a plurality of items of operating equipment being arranged so as to hang in a parallel manner from the upper fastener, and a lower fastener which is arranged so as to hang from the items of operating equipment. The items of operating equipment are connected to the fasteners in each case by flexible contact device.
