As energy demand and generation capacity continue to grow, utilities are looking for distribution switching systems that are reliable, resilient, and efficient.  When used with smart and flexible controls they can minimize the load under outage conditions and maximize their system uptime.

The Scada-Mate SD Switching System with an S&C 6800 Series Automatic Switch Control can meet these technical, operational, and economic challenges. The switching system includes vacuum interrupting technology, has no greenhouse gas and is totally environmentally friendly.

The three-pole operated Scada-Mate SD Switching System is designed for overhead distributed automation and to operate in 14.4-kV and 25-kV power distribution systems. It is rated 900 amperes continuous and interrupting and features peak withstand of 41,600 amperes. It has a five-time duty-cycle fault-closing rating of 12,500 amperes RMS symmetrical.

S&C Regulator Bypass Switches are used to bypass and isolate voltage regulators for maintenance. They’re also suitable for bypassing and isolating other devices, such as the current transformers of primary metering equipment. These switches feature a no-external-arc interrupter for breaking the magnetizing current of the regulator.

S&C’s Regulator Bypass Switches are manufactured in accordance with a quality system certified to ISO9001:2000.

Loadbuster Disconnect Switches, when used with the Loadbuster tool, S&C’s portable loadbreak tool, provide the ultimate in low-cost, universal live switching. They offer the operating flexibility of a system with multipoint interrupter switches . . . without the cost associated with building an interrupter into every switch.

S&C’s Loadbuster Disconnect Switches are manufactured in accordance with a quality system certified to ISO9001:2000.

Recloser Bypass Disconnects are used in combination with a separately mounted S&C Loadbuster Disconnect® Switch to bypass and isolate automatic circuit reclosers for maintenance or inspection. These station-type devices are also suitable for other applications, such as bypassing and isolating current transformers.

S&C Recloser Bypass Disconnects are available in voltage ratings of 14.4 kV, 25 kV, and 34.5 kV and, depending on which S&C Recloser Bypass Disconnect is specified, can be applied on circuits having a continuous current level through 600 amperes.

Scada-Mate Switches are integer style three-pole, group-operated load interrupter switches available in voltage ratings of 14.4 kV through 34.5 kV. They’re factory-assembled on a one-piece base and include an integral stored-energy operating mechanism. Circuit making and breaking are accomplished within sealed interrupters, in a controlled SF6 environment.

All functions — sensing, control, and communication — are provided in one economical, completely self-contained, fully tested, integrated package.

The Loadbuster tool is the original lightweight, easy-to-use portable loadbreak tool for use with disconnects, cutouts, power fuses, and fuse limiters. It brings load-switching capability through 34.5 kV and 600 amperes nominal, 900 amperes maximum to your overhead distribution system.

The Loadbuster tool cuts installation and operation costs. There’s no need for load interrupters on each device. Switching procedures are simplified too . . . minimizing the duration and scope of outages. This rugged, reliable device interrupts with no external arc, meeting OSHA requirements for opening circuits under load.

S&C Alduti-Rupter Switches provide no-external-arc circuit interruption for overhead distribution feeders and outdoor distribution substations. They are ideally suited for the following switching duties:

• Line switching
• Transformer switching
• Cable switching

Alduti-Rupter Switches are available in voltage ratings through 69 kV in seven rugged group-operated, three-pole styles. They can be tailored to suit any configuration and mount on any structure. Alduti-Rupter Switches are offered in ratings of 600 through 2400 amperes continuous and 1600 amperes interrupting.
