Abstract: 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.

Abstract: An insulator includes an end fitting and a connecting device disposed on the end fitting for connecting the insulator to a suspension device. The insulator also includes an additional operating device. The end fitting and the connecting device are formed in one piece. An arrangement is also provided for dissipating overvoltage using the insulator according to the invention.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A fastening clamp for holding objects on a profiled support reliably secures the objects to the profiled support for extended periods of time. The clamp has two clamping brackets which are disposed opposite to each other in a clamping direction and delimit a clamping gap configured to receive a leg of the profiled support. At least one connection web is rigidly connected to the clamping brackets, a clamp element pressing device is connected to the clamping brackets and configured to generate a clamping force in the clamping direction, a transverse clamping unit is fastened to the clamping brackets or to one of the connection webs and has a clamping tongue configured to reach behind the profiled support, and a clamping tongue contact pressure device is connected to the transverse clamping unit and configured to apply a transverse clamping force to the clamping tongue.
