ABSTRACT:
To install a high voltage device, particularly a high voltage breaker having two interrupting chambers and a high voltage insulator in a simple earthquake resistant manner, an end flange of the high voltage insulator on the ground potential side is rotatably suspended from the support beam of a steel frame. A vibration damper is preferably provided between the high voltage breaker and its suspension device. The vibration damper is attached to a ball received in a socket which is mounted on the support beam. The two interrupting chambers which are connected to one another in a V-shape, are connected to high voltage lines. This inverted suspension is also suitable for current and voltage transformers and overvoltage arresters.
