CUTOUT-ARRESTERCombinations,page 14

Application

The primary purpose of any cutout is to provide protection to thelines of your system and the various apparatus on those linessuch as transformers and capacitor banks. Chance Type Ccutouts provide reliable protection from low-level overloadsthat just melt the fuse link, intermediate faults, and very highfaults, through maximum interrupt capacity.

In addition, Type C cutouts can also be used as a sectionalizingdevice. With the use of a portable loadbreak tool, Type C cutoutscan function much like an overhead disconnect switch. Thereare 300 amp disconnect blade Type C cutouts available.

Ratings/Specifications

STANDARD Type C cutouts have maximum design voltageratings to simplify the confusing ratings of cutouts. There areno restrictions on application to grounded wye, ungroundedwye, or delta systems having maximum operating voltages(line-to-line) equal to or less than the cutout maximum designvoltage rating. (See the LINKBREAK and LOADBREAK cut-outs for their specifications.) Interruption tests have beenperformed at full system line-to-line voltage. In each voltageclass, there are continuous current ratings of 100 amps, 200amps and 300 amps. See the table on page 6 for other specifica-tions.

Insulators

The insulators used on Type C cutouts are a sky-glaze gray.The metal to metal leakage distance on the 15 kV cutoutinsulator is 8.7 inches (220 mm), 12.6 inches (320 mm) on the27 kV (125 kV BIL), 17.3 inches (440 mm) on the 27 kV (150kV BIL), 26 inches (660 mm) on the 36 kV (170 kV BIL), and28.4 inches (720 mm) on the 36 kV (170 kV BIL) .

Fuseholders

The solid cap on the single vent fuseholder is a copper alloy,silver-plated to provide efficient current transfer. An integralring is provided in the top tube casting for opening andclosing the fuseholder with conventional disconnect toolsfrom the ground, from a bucket truck or from the pole.

The toggle type trunnion casting is a selective silver-plated bronze for efficient current transfer to the lowerhinge contacts. A cam shaped projection on each side of thetrunnion casting provides high pressure parallel currentpaths to the lower contacts. These projections, or pivot pins,are cast full round for smooth rotational operation in thehinge. The link ejector assists in arc interruption during lowfault current or excessive overload conditions. A groove in thecenter of the link ejector allows the fuse link’s pigtail to godirectly from the fuse tube to the attachment nut. A curvedejector minimizes bending stresses in the pigtail to preventbroken strands. A stainless steel torsion spring on the linkejector helps to rapidly eject the link from the bore of thefuseholder during interruption. The 200 amp link ejector hasa wider groove area and increased spring force to accommo-date the larger links.

The link ejector is pinned to the trunnion casting with astainless steel pin to provide resistance to corrosive elementsand provide smooth pivotal action. An interlocking featurebetween the link ejector and tube casting prevents excessivetension on the fuse link during closure, thereby preventinglink breakage.

The link ejector employs a hammer effect to enhance toggleaction of the trunnion during low fault and overload interrup-tions, hence dropout action is enhanced. The link ejectorprovides sufficient surface area to facilitate re-fusing bylinemen wearing gloves.

Quality Construction

Efficient Current Transfer

The Chance Type C cutout has an all copper current path. Allcontacts are silver-plated. Terminals are tin-plated bronzefor use with copper or aluminum conductors.

Loadbreak Hooks

Galvanized steel hooks are standard on all Type C cutouts,except the arc chute version, for use with a portable loadbreaktool. These sturdy hooks are mounted on the top support andserve to guide the fuseholder into the latch socket whenclosing at an off-center angle.

Top Contact

The top contact is attached to the galvanized-steel hood by astainless rivet to provide a smooth self-aligning action duringclosing even in severely corrosive environments. The topcontact provides a socket-type cavity for latching the fuse-holder and prevents any possible “over-travel” of the fuse-holder. The top contact is made of a highly conductive copperstrip with silver-plated embossments to resist corrosion. Thecontacts are held under constant pressure designed to main-tain firm contact with the fuseholder contact surface untilfault interruption is accomplished.

Hinge

The hinge on the Type C cutout employs large pivot areas forthe fuseholder’s trunnion and is cast of a copper alloy chosenfor its strength and corrosion resistance. The hinge contactsare highly conductive copper alloy stampings and are platedto assure low resistance current transfer from the trunnioncasting. The parallel current paths are backed up by highstrength cantilever springs and are riveted to the hingecastings. Fuseholder can be dropped into place and easilylifted up and out. No tricky maneuvering.

Type C STANDARD Cutout

Chance Type C fuseholders are also mutually interchangeable with the S & C Electric Company’s Type XS cutout.

PRODUCT FEATURES

InterchangeabilityChance was the first to design a cutout that could inter-change fuseholders and mounting assemblies with those ofanother manufacture. Standard Type C fuseholders andmounting assemblies are mutually interchangeable with theS&C Electric Company’s Type XS cutout (within the samevoltage class).

FusetubeThe 1⁄2-inch inside diameter of the Type C cutout’s 100ampere fusetube increases internal pressure giving superiorand reliable expulsion action. During frequently encoun-tered intermediate fault ranges this diameter also permitshigher TRV (transient recovery voltage) values to be toler-ated. This small bore design eliminates any concern relatedto high impedance phase-to-phase faults on ungrounded wyeand delta systems.

The inside liner is constructed of a synthetic arc-quenchingmaterial. The tube is made of fiberglass which permits thesmaller bore and provides a higher burst strength. It isprotected from the weather and environment by a specialultra-violet resistant coating.

Also, the Chance fusetube operates with fuselinks from allmajor suppliers.

BracketsC cutouts come packed one per carton including a NEMAHeavy Duty “B” bracket with captive 11⁄2" bolt for crossarmmounting.

Type X brackets, also for crossarm mounting, provides 25⁄8"additional clearance between the crossarm and the cutout.

“D” brackets are used to mount cutouts and/or arrestersdirectly to the pole. Three brackets may be used for three-phase application. Type D brackets provide a clean, quickmounting without crossarm or special pole bands.

All the above brackets are galvanized steel for long lastingservice. Cutouts can be ordered without any brackets.

Higher Interrupt CapacitiesBy using a copper arc shortening rod inside the top of thefusetube, higher interrupt ratings are obtainable. An arcshortening rod is attached to the cap of some fusetubes andlowers the fuse link within the fusetube. This permits a muchshorter arc, resulting in less arc energy, and higher inter-rupting capacities.

For 200 A tubes, it allows for full voltage rating.

It is necessary to use fuse links with removable buttonheadswhen arc shortening rods are employed.

170 kV BILA 170 kV BIL Type C cutout is available for use in areaswhere the 28.4-inch minimum leakage distance to ground isrequired. See ordering data, page 6.

Extra Corrosion Protection (150 and 170 kV BIL only)Type C cutouts are available with components of stainlesssteel inserts, hood and bolts, and copper alloy loadbreakhooks to offer greater corrosion resistance for environmentalareas where corrosion can become a major factor. To order astainless steel/copper alloy cutout add the suffix “S” to theend of the catalog number with the rating specificationsdesired. In additon, an optional spring assist may be providedto further enhance the toggle and drop out action in highlycorrosive applications.

TerminalsTin-plated bronze parallel groove type terminals are stan-dard on Type C cutouts. They can accommodate aluminum orcopper conductor sizes ranging from No. 6 (13.3 mm2) solidcopper through 4/0 (160.6 mm2) ACSR or 250 (167.5 mm2)kcmil stranded copper. The parallel groove design is perfectfor handling two different sizes of conductor as is the casewhen arresters are being used. Eyebolts are also available.See ordering data, page 10A-7.

15 kv - 110 kV BIL15/27 kV - 125 kV BIL

changeable with any other manufacturer’s cutout.

All standard non-loadbreak fuseholders and the linkbreakfuseholders are interchangeable and fit into both the non-loadbreak and Type C LINKBREAK cutout mounting assem-blies produced after January 1985. Mounting assemblies aresame as Type C STANDARD cutouts, shown on page 10A-7.

Ratings / SpecificationsThe 15 kV Type C LINKBREAK cutout has a maximumdesign voltage rating of 15 kV. There are no voltage restric-tions on application to grounded wye, ungrounded wye, ordelta systems having maximum operating voltages (line toline) equal to or less than the cutout maximum design voltagerating.

The 15/27 and 22/36.4 kV Type C LINKBREAK cutouts havemaximum design slant voltage ratings. These cutouts are tobe used on systems which have phase-to-ground voltages nogreater than the value listed to the left of the slant (/) andwhich have phase-to-phase voltages no greater than thevalue listed to the right of the slant.

The Type C LINKBREAK cutout is to be used with onlyChance, McGraw-Edison and Kearney fuselinks. S&C Elec-tric fuselinks and other fuselinks which require more than 1inch elongation before breaking must not be used with theType C LINKBREAK cutout.

A sharp downward pull on the lever with a hookstickbreaks the fuselink.

15 kV - 110 kV BIL unit

ApplicationThe Chance Type C 100 amp LINKBREAK cutout providesshort circuit protection to utility lines with the added featureof mechanical linkbreak capability in a loadbreaking func-tion. Linkbreak cutouts provide reliable protection fromoverloads that just melt the fuselink through the maximuminterrupt capacity of the fuseholder and also provide induc-tive and capacitive loadbreak capability. For loadbreak rat-ings see chart, next page.

The unit will also accept the Type C 200 amp non-loadbreakfuseholder or a 300 amp disconnect blade. Each LINKBREAKcutout includes standard loadbreak hooks to use with por-table loadbreak tools. This method is particularly useful forswitching of the 200 amp fuseholder and 300 amp disconnectblade.

Design / Product FeaturesConstruction and product details shown on page 10A-3 applyto the LINKBREAK cutout except that the link-ejector on thelinkbreak fuseholder is a copper-alloy casting instead of astainless-steel stamping.

The unit utilizes a stainless-steel linkbreak lever to mechani-cally break fuselink elements thereby obtaining load inter-ruption within the fuseholder. The long lever is positioneddirectly in-line with the cutout, rather than on one side or inback of the cutout for convenient pull-down operation.

Application

The Type C Loadbreak Cutout is available for application on15, 25 and 35 kV distribution systems. The addition of the arcchute expands the flexibility of the Chance protective devicesfamily by providing loadbreak capability for cutouts anddisconnect solid blade units. The loadbreak cutout providesshort circuit protection to utility lines with the added featureof a loadbreaking function.

The loadbreak cutout is applicable for transformer andcapacitor bank switching or line sectionalizing.Loadbreak cutouts provide protection from overloads thatjust melt the fuselink through the maximum interruptcapacity of the fuseholder. They also provide loadbreakcapability through 300 amperes.

Design

All design features and most components of the loadbreakunit are identical to those incorporated in the Type C stan-dard cutout. The loadbreak portion of the Type C Loadbreakcutout is a heavy duty, reliable load interrupter that providesa positive visible loadbreak. A common loadbreak mountingassembly will accept the Chance Type C 100 amp and 200amp loadbreak fuseholders or a 300 amp loadbreak discon-nect blade.

Ratings/Specifications

The 15kV Type C loadbreak cutout has a maximum designvoltage rating of 15kV. There are no voltage restrictions onapplicaton to grounded wye, ungrounded wye, or delta sys-tems having maximum operating voltages (line to line) equalto or less than the cutout maximum design voltage rating.

The 15/27 and 20/34.5 kV Type C loadbreak cutouts havemaximum design slant voltage ratings. These cutouts are tobe used on systems which have phase-to-ground voltages nogreater than the value listed to the left of the slant (/) andwhich have phase-to-phase voltages no greater than thevalue listed to the right of the slant.

Fuseholders and mounting assemblies from other manufac-turers' loadbreak cutouts are not interchangeable withChance loadbreak cutouts. Likewise, Chance fuseholdersand mountings are not interchangeable with other manufac-turers' loadbreak cutouts.

Operation

The self-contained loadbreak device enables the lineman tointerrupt load current by means of a simple hookstick opera-tion. To break the current, the lineman inserts a hookstickinto the operating ring and rapidly opens the device. Uponopening, a spring-loaded stainless steel blade mechanismsnaps out through a gray arc chute and elongates, cools andextinguishes the confined arc. The loadbreaking operation isindependent of the operating speed of the lineman. The fuseremains undamaged. No special or portable tools are re-quired to operate the unit. In the open position, the fuse-holder or blade hangs in an approximate vertical position forthe visible-break.
