    摘要: An electrical switch which includes an insulative housing having a wall defining an axial bore therein, a first electrical contact disposed in the housing bore and a second electrical contact movably disposed in the housing bore between an open position and a closed position. When the contacts are in their open position, the second electrical contact is spaced apart from the first electrical contact and when the contacts are in their closed position, the second electrical contact is in electrical contact with the first electrical contact. The switch includes features to enhance safety and operation by reducing the possibility of arcing or flashover before and during the switching operation and to provide of visual indication of the state of the switch.

    摘要: An electrical connector component for sending and receiving communication signals through a power distribution line generally includes an internal conductor, an insulative housing surrounding the conductor and a signal filtering device having a medium-voltage end in electrical contact with the internal conductor and an opposite low-voltage terminal. The signal filtering device is adapted to substantially block passage of power signals yet substantially permit passage of communication signals between the medium-voltage end and the low-voltage terminal. In a method for sending and receiving communication signals through a power distribution line, an access point on a power distribution line is provided without de-energizing the power distribution line, passage of power signals through the access point is blocked and passage of communication signals through the access point are permitted.

    摘要: A high voltage loadbreak bushing insert includes an insulative housing having a first end section, a second end section opposite the first end section, a mid-section disposed between the first and second end sections and a transition shoulder portion disposed between the second end section and the mid-section. The second end section is dimensioned for insertion into a power cable elbow connector and the mid-section is dimensioned to be sealed against an elbow cuff of the power cable elbow connector. The transition shoulder portion includes at least one raised portion protruding radially outwardly from the transition shoulder portion. The raised portion is adapted to force the elbow cuff of the power cable elbow connector to expand in a radially outward direction upon withdrawal of the second end section from the power cable elbow connector, thereby venting a cavity formed between the bushing insert and the power cable elbow connector.
