Type PSI/II Live-Front 6-Compartment Pad-Mounted Switchgear

  • 15 kV
  • Available as UL® listed
  • Live-front 600-Ampere Switch Compartments
  • Live-front 200-Ampere Fuse Compartments
  • Manual, Automatic Source Transfer and SCADA Controlled
  • An exceptional combination of switch (up to 5) and fuse (up to 5) compartments, including bus-tie configurations
  • Meets IEEE C37.74 requirements, including 3-time fault-closing of switches
  • Meets enclosure security requirements in ANSI C57.12.28

Federal Pacific 6-Compartment, Live-front Pad-mounted Switchgear (available as UL® listed) provides the convenience of installing a single enclosure with two 600-ampere switches and up to four three-phase sets of fuses. Installations with concentrated loads can now be served from a single switchgear assembly. The six-compartment configurations require less land space than two four-compartment units, which was the only choice in the past. In addition, the 6-compartment units are more economical than two four-compartment units both in initial and installed costs. There is no sacrifice in operating flexibility and as a result, an outage on the main-feeder cable can be readily isolated and sectionalized. For 8-compartment designs, consult the factory.

Type PSE Dead-Front Pad-Mounted Switchgear

Federal Pacific Manual Dead-Front Type PSE Pad-Mounted Switchgear meets or exceed all ratings in IEEE C37.74 and with UL® listing of both 15 kV and 25 kV models. The enclosure provides increased security of fuse and switch components from environmental concerns and enhanced isolation of medium-voltage circuits to limit exposure of operating personnel.

Federal Pacific PSE pad-mounts feature a low-profile, heavy-gauge enclosure with cross-kinked roof to eliminate potential for standing water. Stainless-steel hinges and hinge pins combined with padlockable, self-resetting, three-point auto-latch door security system assures durability while controlling access to the interior.

Double-door construction allows clear access to elbow terminations. Ground rods that are full width of door opening make grounding of circuits and installation of surge arresters easy to achieve using shotgun clampstick. Enclosure bottom flange includes gasketing to isolate and protect the finish during installation and throughout the service life of the switchgear. Galvanized-steel floor plate on bottom of compartment containing medium-voltage components isolates interior from moisture and ingress of other contaminates.

The electrostatically deposited, baked-on powder epoxy finish meets IEEE, ANSI and UL® requirements and provides a tough, durable high-gloss finish with protective qualities essential to insure long-term protection of the metal.

Type PAV -15kV Pad-Mounted Air-Insulated Vacuum Switchgear

  • Footprint – Same as equivalent conventional 15kV dead-front pad-mounted switchgear configurations.
  • 33″ Bushing Height – Same as conventional dead-front pad-mounted switchgear.
  • Cable Configuration – Same as conventional 4-compartment and 2-compartment dead-front pad-mounted switchgear.
  • Vacuum Bottle Technology – Provides two thousand (2000) mechanical operations.
  • 630A Three-Phase Vacuum Switches – with visible isolation blades, tested to C37.74.
  • Vacuum Fault Interrupters – Eliminate fuses on the load taps up to 630A continuous, tested to C37.60.
  • Three-phase Load-Side Fault Interruption – Eliminates “single-phasing” of three-phase loads.
  • No External Power or Battery Sources are required to manually close (and trip open) switch or fault interrupter positions.
  • “Trip Free” Operation – Allows the interrupter to trip open immediately if closed into a fault.
  • CT-Powered Relay Option – Eliminates the need for a UPS or other battery back-up. Other relays and power options are available. Consult factory.
  • Fully Rated, Interlocked, Visible Isolation – Isolation blades are interlocked with vacuum bottles to prevent load switching with the isolation blades, providing full voltage and BIL withstand gap when open, irrespective of vacuum bottle contact position.
  • Visible Isolation Blades are lockable.
  • Base Adapters (Optionally Available) – Provide an easy transition from existing live-front pad-mount installations to a vacuum solution

Federal Pacific’s Type PAV (Pad-mounted Air-insulated Vacuum) pad-mounted switchgear is designed for seamless integration of vacuum bottle technology into existing URD systems as well as for Commercial/Industrial applications.

The Type PAV (Pad-mounted Air-insulated Vacuum) pad-mounted switchgear, features vacuum fault interrupter and/or vacuum load interrupter switch designs, both of which provide integral and interlocked visible isolation blades.

The PAV requires no external power or battery source for basic switching operations and offers a CT-powered relay option for fault interruption, with no additional external power required. This technology affords “trip-free” operation and enables the PAV to provide 2,000 mechanical operations, while offering the same footprint, bushing height and cable configuration as conventional, dead-front pad-mounted switchgear.

In addition, the PAV is available with an optional base adapter, which facilitates an easy transition from existing live-front pad-mounted installations to a vacuum solution in conventional 4 – compartment and 2 – compartment designs.

The Type PAV switchgear provides a convenient alternative option to upgrade from conventional pad-mounted traditional switch-fuse products for customers who need resettable fault interrupter solutions, three-phase protection to prevent “single-phasing” larger loads, and/or require more switching operations than is available with conventional air-break switches.

Fitting a vacuum product into the footprint of conventional dead-front pad-mounted switchgear often has been a challenge up to this point, but Federal Pacific is now able to match the footprint of conventional PSE dead-front switchgear. If a customer has already purchased conventional air-break switch-fuse switchgear products and wants to upgrade to a vacuum interrupter technology, the PAV fits the common existing dead-front pad-mount footprints, such as the PSE switchgear, and, with the use of a base adapter of live-front pad-mounted switchgear, such as the PSI/II switchgear.

Due to these unique features, the PAV provides Customers the forward-looking flexibility  to easily integrate basic vacuum technology into their existing distribution systems, replacing dead-front or live-front switchgear, with room to enhance the technology and operational features with the addition of external power and communications.

  • 15 kV – 25 kV
  • Visible Disconnect on each vacuum interrupter
  • Vacuum Interrupter Switches – 200 amp and 600 amp
  • Resettable Vacuum Fault Interrupters – 200 amp and 600 amp

  • Two-Way and Multi-Way configurations
  • Front Access or Front and Rear Access
  • External Manual or Motor Operation
  • 200 amp bushing wells
  • 600 amp bushings
  • Insulated Main Bus

Federal Pacific PVE Models of Pad-Mounted Switchgear combine air-insulated vacuum load-break interrupters for switching of primary feeders with air=-insulated vacuum fault interrupters for protection of lateral load-feeder circuits. These vacuum switching and protection components are arranged in a variety of circuit configurations to provide the range of choices typically available in all other types of pad-mounted switchgear, including manual, supervisory-controlled, automatic-transfer and automatic sectionalizing (self-restoring) models. The vacuum interrupters are enveloped in a rugged 11-gauge steel enclosure with cable connections through 600 ampere bushings or 200 ampere bushing wells chieving a dead-front design with high-voltage components isolated from the environment by a galvanized steel floor plate.
