| A switch is provided for insertion directly into a high voltage power line to provide means for electrically disconnecting an extension of the line. The switch employs an insulator having high tensile strength and a high dielectric constant which can physically support a power line and also withstand the electrical forces applied through the line. The electrical circuits are either completed or broken through action of a switch blade which can conduct electric current between hardware components connected to end fittings on the insulator. The end fittings are tapered and faced by steps to prevent their being pulled from the hardware or rotated with respect to the hardware.

| Disconnecting switch assemblies are located in a triangular configuration on an inverted cross-shaped frame adapted to be secured to the top of a power line pole. Each switch assembly includes a pivotally mounted insulator carrying a switch blade for engaging a stationary contact carried by a stationary insulator. The pivoted insulators at the ends of the transverse piece are interconnected by a shaft which is connected by a link to the pivoted insulator at the top of the upright piece to effect conjoint switch operation. The transverse and vertical pieces are tubular and the shaft and link are enclosed thereby. Dead end connections adjacent the switch assemblies permit dead ending the respective conductor thereto. Each switch blade and the respective switch contact are so positioned that the switch blade cannot gravitate to the open position when closed and vice versa. Each switch contact is carried by an insulator that is mounted at the distal end of a support bracket in angular relation to the respective pivoted insulator.

A new and improved apparatus is provided to permit a live or hot electrical power line to be cut in the field for line service or other purposes. The apparatus is connected at each end to the line at positions spanning the site of the cut. The attached end portions are then moved closer to each other, easing the tension on the portion of the line to be cut. The apparatus is then connected to the live line with jumper cables, forming a parallel electric circuit. The line is then cut and a cut end tied back. Flow of current through the apparatus is broken. An interrupter in the apparatus suppresses any arc which may tend to form. |
