The invention relates to a conductor (2) for electrical equipment, the conductor comprising at least one hollow section member (2) of electrically conductive material that is elongate along a longitudinal axis (Y), the conductor having an outside surface in which at least a portion forms corrugations (23, 24) in a plane perpendicular to the longitudinal axis. The conductor may advantageously form a movable contact (blade) (2) of a high voltage disconnector.

A railroad vehicle includes a plurality of vehicle units, a cable, and a disconnector. In the plurality of vehicle units respective vehicles are coupled. The cable is placed astride the vehicles to connect the power supply unit of each vehicle unit. The disconnector is installed at some midpoint in the cable and electrically separates the vehicle units from one another.

A high voltage folding disconnect switch including a folding switch blade that folds as it opens or closes and which is divided into a fixed blade portion attached to a rotating insulator and a folded blade portion having an electric contact surface engaging a break jaw contact surface. A trigger lever-locking bar is mounted to the fixed blade portion. The trigger lever-locking bar includes a trigger finger for contacting a trigger surface mounted on a stationary insulator. The trigger lever-locking bar has a cam slot for interaction with a cam follower pin that locks the movement of the folding blade so that premature straightening of the blade is prevented until any ice build-up on the switch has been alleviated.

A blade position detector and rollover indicator is operatively attached to an elongated movable switch-blade assembly of a horizontally mounted high voltage vertical break disconnect switch. The blade position detector and rollover indicator is gravity responsive and attached in predetermined position to the elongated disconnect blade assembly that reacts when the proper angle of closure of the blade is obtained in an intermediated closed switch position and finally when the proper angle of blade rollover is obtained in a fully closed switch position to provide a visual indication of full closure of the disconnect switch.

A switch assembly that includes a cutout mounted fault interrupting switching device and ice shields that block ice build-up on the assembly that may otherwise impede a dropout operation of the switching device. The switching device includes a switch, an upper electrical contact and a lower electrical contact. The switch assembly includes an upper coupling assembly configured to releasably engage the upper electrical contact and a lower coupling assembly configured to engage the lower electrical contact in a pivoting engagement, where the switching device is operable to pivot relative to the lower coupling assembly when the upper electrical contact is released from the upper coupling assembly. The switch assembly further includes an upper ice shield coupled to and formed over the upper coupling assembly and a lower ice shield coupled to and formed over the lower coupling assembly.

A system for collecting information related to an electrical switch. The system including a first switch, a second switch, and an external device. The external device is configured to receive the first and second signals corresponding to the first and second switches. Wherein the external device is located remotely from the first switch and the second switch.

The invention relates to a fast earthing switch including two contact members of which at least one contact member is movable along an actuation direction in relation to the other contact member between a closed position, in which the contact members are electrically connected, and an open position, in which the contact members are electrically unconnected, the contact members defining an arcing region in which an arc is generated during a current interrupting operation and in which an arc-quenching medium is present; and an insulating member that is electrically insulating; wherein the movable contact member includes a first channel that at least sectionally extends along the actuation direction, the insulating member includes a second channel that at least sectionally extends along the actuation direction, the insulating member and the movable contact member are coupled to each other and the channels are in fluid communication to direct the arc-quenching medium.

A vertical break disconnector for electrical connection or disconnection is described. The vertical break disconnector is provided with a first and second housing unit with one or more contacts for electrical current conduction. The first housing unit supports an engagement mechanism to engage or disengage with the one or more contacts of the first and second housing unit to electrically close or open the vertical break disconnector. The engagement mechanism includes a conducting element pivotably coupled to the first housing unit at a first end of the conducting element over a rotating shaft a rotating lever mounted on the first housing unit and a connecting link mounted on the first end of the conducting element to couple the conducting element to the rotating lever. In operation, the rotating lever causes the conducting element to turn and twist to electrically close or open the vertical break disconnector.
