An item of electrical equipment includes a core clad with a glass fiber material. The glass fiber material is preimpregnated with a resin. A layer of a substance is applied to the glass fiber material. The substance is formed at least partly of high-temperature vulcanizing silicone rubber. A corresponding production method is also provided.

Surge arrester and production method for a surge arrester

An arrangement and a method have precisely one resistor stack for switching high voltages. The arrangement contains a switching device that has two contact devices, which are arranged in an insulator. The contact devices are separated from each other by a separation path, wherein the separation path can be bridged by a movable contact piece. One contact device is in contact with the resistor stack in a common housing. The common housing is formed by a direct coating of the resistor stack and the insulator.

Arrangement and method for switching high voltages having a switching device and precisely one resistor stack

A tensioning device is provided for a surge arrester having an end fitting and tensioner. The tensioning device has an axial clearance for receiving a tensioner and a region being conically tapered in axial direction to be introduced into a clearance of the end fitting being shaped for a substantially exact fit. The conically tapered region has delimitation walls defining the axial clearance for the tensioner being movable toward a clearance interior. An antifriction layer is applied to the surface of the conically tapered region. A production method for a surge arrester and a corresponding surge arrester are also provided.

Tensioning device for a surge arrester, production method and surge arrester

A surge arrester is connected in an output current path from an electrical power supply system. A cut-off arrangement is also provided in the output current path and has a first electrode and a second electrode. The second electrode has a recess in which at least part of a gas generator is arranged. The recess is covered by a cover. When the cut-off arrangement responds, an additional volume for accommodation of expanded gas is provided upon demand, in addition to an arcing area provided in the interior of the cut-off arrangement.

Disconnection arrangement and method for operation of a disconnection arrangement

A circuit breaker device has a first electrode piece and a second electrode piece. In order to ensure protection from weather, the circuit breaker device is equipped with an electrically isolating housing. The electrically isolating housing has a first shell and a second shell. The first shell serves as a volatile casing for the second shell during production.

Disconnecting switch device and method for production of a disconnecting switch device

A surge arrester has a discharge current path. The discharge current path is surrounded by an insulating sleeve. The insulating sleeve has at least one area that is optically transparent.

Surge arrester

The invention relates to a surge voltage protector () which comprises a discharge current path with at least one varistor block (). In order to prevent the varistor blocks () from bursting when an inner error is produced and an electric arc connected thereto is created, a coating () is applied in the region of the outer covering area of at least one varistor block (), said coating being made of a substance which triggers an electric flashover when a critical temperature of the varistor blocks () is exceeded.
