Type AR (Automation-Ready)Switch

14.4kV, 25kV or 34.5kV  900 Amperes Continuous/Interrupt

Description

The Hubbell unitized Type AR switch is a distribution-level,loadbreak,gang-operatedside-breakswitch designed to meet not only today’s needs but well into utilities’ future of distribution automation. Designed for nominal system voltages of 14.4kV and 25kV threeandfour-wiresystems and 34.5kVgrounded-wyesystems. The Type AR switch is available with a variety of options, and in ratings for present and planned requirements.

To minimize field installation time, the Type AR switch is pre-assembled,adjusted and mounted on a crossarm. Instal- lation time is even faster for a Type AR switch with the hookstick-operationoption.

Variations and Configurations

The Type AR switch is available in five basic configura- tions:

•Horizontal •Vertical •Phase-over-Phase•Delta •Inverted

All feature clockwise opening and are operable by torsional or reciprocating controls as well a hookstick operation option (full-lengthdown-the-polecontrolorcrossarm-mountedhookstick-operationcontrol).

Hook stick Operation  The Type AR switch can be operated by a hook stick operation. This option eliminates control pipe sections down the pole and their attendant adjustment during installation and maintenance.

Extra Pipe  The extra pipe section includes guide, coupling, and all hardware for attachment.

Extension Links  When deadending to the AR switch, exten- sion links must be used to give needed clearance. The end clevis has a slotted hole for inserting the machine bolt with- out having to remove the extension bar. The extension links supplied are 14 inches long,hot-dipgalvanized, and REA accepted. Catalog No. C2070112; six required per switch.

Surge Arrester Brackets Three brackets can be supplied for mounting six surge arresters (utility supplied) for overvoltage protection.

Sensor Brackets Extension Brackets can be supplied, or added to the AR Switch, to allow for the additon of line volt- age/current sensors.

Crossarm Braces Crossarm braces may be specified as an option.

ESPpolymer Insulators  The distribution insulators, 2.25inch bolt circle, are available in aU.S.-manufacturedESP polymerdesign.Theyarelightweight,durable,andtheyofferlong-termperformance in every type of environment.

Terminal Connectors  CatalogNo.ATC1343,fortifiedcadmi- um-platedaluminumparallel-grooveclamp can be supplied with switches. Six per switch.

TheChanceunitizedD7isadistribution-level,gang-operated,side-breakswitchfor15through38 kV applications. It ispre-assembled,adjusted, and mounted on a common support at the factory forthree-phaseservice.D7 switches meet acontinuous-currentratingof 600 amperes, a momentary rating of 40,000 amperes, athree-secondshort time current rating of 25,000 amperes, and applicable NEMA and ANSI standards. It is available in 15 kV (110 kV LIW*), 27 kV (150 kV LIW*), 34.5kV (150kV LIW*) or 38 kV (200 kV LIW*). The D7 is a600-ampereloadbreakswitchwiththeDuogap® expulsioninterrupters.WiththeDuogap,theD7iscapable of switching load currents up to 600 amperes, with full recovery voltage across the switch, and interrupting transformer magnetizing andline-chargingcurrents. This switch may be used for disconnecting, line sectionalizing, circuit breaker bypassing, and isolating.

*Lightning Impulse Withstand (BIL)

Convenient Installation

Field installation time of this pre-assembledswitch is greatly reduced below what is usuallyrequiredtoinstallseparategang-operateddistributionlevelswitches.Thethree-phaseunitisconveniently raised in one piece to its mounting position, secured to the pole, control sections attached, and field adjustment made. Proper synchronization and phase spacing have been made at the factory. Unitized switches are installed in 2 to 4 hours, compared tonon-unitizedswitches that take 6 to 8 hours.

600 Amperes

Chance 15.5, 27 and 38 kV Duogap expulsion interrupters .

The arcing horn will pick up load current upon closing to prevent burning or arc pitting on the main contact surfaces.

Design Features

The jaw socket and hinge terminal castings of the D7 are bronze with tin-platedNEMA terminal pads. The blade is a round tubular copperwithflattenedendstoallowforasilver/coppercontact.Afour-pointsilverplated contact is supplied on the jaw end to make the switch easier to open and close. Anall-coppercurrent path is provided.

Interrupters

Chance Duogap® expulsion interrupter converts any D7 to a loadbreak switch.Built-insockets on each switch accept the interrupter. The Duogap may be ordered with the switch or may behotstick-installedfor load management conversion. For more on the Duogap, see Bulletin No.14-9405.

Terminal Pads, Arcing Horns

Two-holeNEMA terminal pads are standard. The D7 terminal pads are bronze withtin-platingto providelow-resistanceefficient current transfer.

A stainless steel arcing horn is provided to pick up load current, thus preventing burning or arc pitting on the main contacts.

Insulators

The Vee configuration of the insulators simulates a low profile with less bulk and a pleasing visual appearance. The gray-toneinsulator for the unitized D7 switch is NEMA3-inchBC.

15 thru 34.5 kV Switch Base and Bearings

The base castings consist of high strength, high corrosion resistant aluminum alloy. Thislightweight aluminum is comparable to bronzein almost all metal technical categories, such as: ultimate tensile, tensile yield,elongation,hardness,modulusofelasticity,thermalconductivity, and electrical conductivity. Bearings are high-strength,high-densityDelrin, for smooth pivotal action.

Conductorsaredead-endedtoeachindividualswitchbase.Pull-offholesare designed for a6,000-lb.working load rating. The switch frame is limited to an unequal loading of 700 lb.

Common Support

The 4 x 4-inchcommon support member is furnished in either galva- nized-steelor fiberglass tubing. The “interphase” shaft which connects the three rotating insulators is constructed of the same material as the crossarm.

Controls

Controls are either all metal or metal with a vertical fiberglass section. Three options combine the metal or insulated interphase shaft with the metal or fiberglass common support.

Type D6 Switches  —  Non-Unitized

15 to 38 kV

600 Amperes

Application and Ratings

The Chance Type D6 is a distribution-level,gang-operated,side-breakswitch for 15 through 38kV applications. D6 switches meet acontinuous-currentrating of 600 amperes,amomentaryratingof40,000amperes,athree-secondshort-time current rating of 25,000 amperes, and all applicable NEMA and ANSI standards. It is available in 15 kV (110 kV LIW*), 27 kV (150 kV LIW*) and 38 kV (200 kV LIW*). The unit is a600-ampereloadbreak switch with Duogap® expul- sion interrupters. Each switch comes prefitted with a socket to accept the Duogap. Orders also may specify switches come without the interrupters. With the Duogap, D6 is capable of switching load currents up to 600 amperes, with full recov- ery voltage across the switch, and interrupting transformer magnetizing andline-chargingcurrents. The D6 switch may be used for disconnecting, line sectionalizing, circuit breaker bypassing, and isolating.

Design Features

D6 jaw socket and hinge terminal pads are bronze castings withstainlesssteelsupports.Thebladeisroundtubularcop- per with flattened ends to allow for a silver/copper contact. Silver contacts are used to ensure smooth, easy operation.

Bases and Bearings

The switch base for 38 kV (200 kV LIW*) is galvanized-steelhat-section.A sealed, greaseless main bearing supports the rotating insulator. Thestainless-steelballs are encased in ahigh-strength,heat-treatedaluminum housing for mainte- nance-freeoperation.Theswitchbasefor15kV(110kVLIW*)and 27 kV (150 kV LIW*) is extruded aluminum channel and the bearings arehigh-densityDelrin.

Insulators

The Sky-Glaze® insulator is gray porcelain NEMA3-inchBC.

Blade Opening

All side-breakD6 switches open in thecounter-clockwisedirection.

Terminal Pads, Arcing Horn

NEMA-standard,two-holeterminal pads accept aluminum or bronze connectors.Tin-platedbronze D6 pads reduce resistance to assure efficient current transfer. A stainless steel arcing horn picks up load current, preventing burning or arc pitting on the main contacts.

Interrupters

Chance Duogap® expulsion interrupter makes the D6 a loadbreak switch.Built-insockets on each switch accept the interrupter. The Duogap may be ordered with the switch or may behotstick-installedfor load management conversion. For more on the Duogap, see BulletinNo.14-9405.

Alternate Mounting Arrangements

The standard D6 switch design allows for a multitude of mounting and control configurations. The switch can be mounted horizontally or vertically. Controls can be installed on any side of the pole or off the switch ends for structure mount. Some common configurations are shown below. Consult factory for other requirements.
