Group-Operated Switches
General Information
- Description
There are two series of Bridges Electric® group-operated switches: the Topper® Series and the Vector® Series.
The Topper® Series takes its name from the original Topper® Switch, a pole-top only design whose compactness, ease of installation and unique synchronized operation is unequalled. Many additional construction designs are now available in addition to the original pole Topper®. The Topper® Series is conservatively rated and has superior fault close, three second, continuous and loadbreak ratings. The Topper® is available in ratings of 15 kV – 38 kV, 110 kV – 200 kV BIL and 600 A – 1,200 A loadbreak.
The Vector® Series is a line of group-operated air-break (GOAB) switches designed for superior performance in three-phase loadbreak switching while remaining competitive in price. The Vector® is available in ratings of 15/25 kV and 38 kV, 150 kV and 200 kV BIL, 900 or 1,200 A continuous current and 600 or 900 A loadbreak.

Description
The Bridges Electric™ Vector® series is a line of group-operated switches designed for superior performance in three-phase loadbreak switching while remaining competitive in price. The Vector is available in ratings of 15/25 kV and 38 kV, 150 kV BIL and 200 kV BIL, 900 A or 1,200 A continuous current and 600 A or 900 A loadbreak. The Vector is manufactured as a true unitized switch; it is not three single-phase switches mounted to a crossarm. The switch is completely factory assembled and adjusted eliminating the need for fine tuning in the field following the installation of the switch. The standard Vector switch incorporates bolt-on interrupters; plug-in interrupters are available as an option.
The unique base assembly consists of a 3” x 5” (76 mm x 127 mm) galvanized steel or 4” x 6” (102 mm x 152 mm) fiberglass tubular housing, oil impregnated sinter bronze bushings, “O” rings with covers and stainless steel end caps (ABS plastic for fiberglass base) that enclose the operating mechanism of the switch for superior weather protection. The internal operating mechanism incorporates an innovative balanced-force concept for easeof operation by balancing the leverage forces on the rotating insulators.
Installation is made simple with the factory-installed “single-point lift bracket.” Provisions for dead-ending all three conductors is standard (on most models) along with the “pole hugger” design for aesthetics. All Vector® series switches are available in pipe-operated versions, hookstick-operated gang (the HOG) versions and motorized versions with SCADA control.

- Galvanized steel extended arrester bracket set - option A2.
Enclosed Operating Mechanism
Enclosed Operating Mechanism
Simple, Conservative Design
Unique push-pull action of the two interposing rods balances the forces acting on the rotating insulator shafts. The internal operating mechanism gives a very clean and pleasing appearance. It also provides weather protection.
- Internal operating rods - plated steel on steel base, fiberglass rods on fiberglass base
- 4" x 6" (102 mm x 152 mm) fiberglass switch base
- Blade, hinge and jaw terminals are 3/8" x 2" (10 mm x 51 mm); 1/2" x 2" (13 mm x 51 mm) for 1,200 A
- Contact pressure is preset at the factory by use of a stainless steel spring and mechanical nut
- Silver washers (two per side) provide an excellent mechanical swivel point, as well as a sound electrical connection
- Two-hole tinned terminal pads - standard on 900 A; four-hole pads standard on 1,200 A
- 3" x 5" (76 mm x 127 mm) hot-dipped galvanized steel base.
Automation
Automation
The Bridges ElectricTM line of switches is very versatile when it comes to operating a motorized switch locally or remotely. The Auto Vector (AV), AutoPack Vector (APV), Auto-Throwover (ATO) and Auto-Sectionalizer are all reliable means of motorized switching and are each tailored to meet the specific needs of electric utilities. We can offer voltage sensors mounted directly to the switch unit for three-phase voltage monitoring, as well as the Bridges Electric Remote Current Monitoring System (RCMS), which is a cost effective alternative for current monitoring and fault detection. The Bridges Electric line of switches has provided reliable solutions to electric utilities for their distribution automation needs for many years.
