15 kV, 200A

GENERALThe Cooper Power Systems LoadbreakElbow Connector is a fully-shieldedand insulated plug-in termination forconnecting underground cable totransformers, switching cabinets andjunctions equipped with loadbreakbushings. The elbow connector andbushing insert comprise the essentialcomponents of all loadbreak connections.

Cooper Loadbreak Elbows are moldedusing high quality peroxide-curedinsulating and semi-conducting EPDMrubber. Standard features include acoppertop connector, tin-plated copperloadbreak probe with an ablative arc-follower tip and stainless steelreinforced pulling-eye. An optionalcapacitive test point, made of corrosionresistant plastic, is available for usewith fault indicators (see CatalogSection 320-10).

Cable ranges are sized to accept awide range of cable conductor andinsulation sizes. This range takingallows the same elbow to be used oneither 175 mil or 220 mil cable withina given conductor size.

The coppertop compression connectoris a standard item to transition from thecable to the loadbreak probe. An aluminum crimp barrel is inertia-weldedto a copper lug. The aluminum barrelmakes the connector easy to crimpand the copper lug ensures a reliable,tight, cool operating connection withthe loadbreak probe.

INSTALLATIONCable stripping and scoring tools,available from various tool manufac-turers, are recommended for usewhen installing loadbreak elbows. Afterpreparing the cable, the elbow housingis pushed onto the cable. The loadbreakprobe is threaded into the coppertopconnector using the supplied installationtool or an approved equivalent. Use ashotgun stick to perform loadmake andloadbreak operations. Refer toInstallation Sheet S500-10-1(5000050751) for details.

(6) LBI215 Loadbreak Bushing Inserts

15 kV, 200A

GENERALThe Cooper Power Systems RTE®

Bushing Insert threads into a universalbushing well to provide the samefunction as an integral loadbreakbushing. Using bushing inserts makesfield installation and replacementpossible and efficient. Bushinginserts and elbow connectors comprise the essential componentsof all loadbreak connections.

The RTE Bushing Insert uses apatented “ALL COPPER CURRENTPATH,” containing only one currenttransfer point, within the insert itself.The uncomplicated nature of the cur-rent path design delivers superior,reliable performance.

An internal hex broach allows forpositive torque controlled installation.Using the optional installation torquetool the bushing insert can be proper-ly tightened into the bushing well with-out the fear of accidentally breakingthe bushing well stud.

Cooper's exclusive latch indicatorring, located on the circumference ofthe bushing's collar, eliminates theguesswork of loadbreak elbow instal-lation on the bushing insert. Thebright yellow ring provides immediatefeedback to determine if the elbow isproperly installed on the insert. If theyellow ring is completely covered bythe loadbreak elbow, it is fully"latched," if the ring is visible, theelbow can be installed correctlybefore any problems can occur.

The bushing insert meets all therequirements of ANSI/IEEE Standard386 and is completely interchangeablewith mating products that also meetANSI/IEEE Standard 386. Whenmated with a comparably ratedcomponent, the bushing insert providesa fully shielded and submersibleconnection for loadbreak operation.

INSTALLATIONNo special tools are necessary. The insert can be installed by handor with the assistance of a torque tool.Using the hex-broached base (seeFigure 2) and the optional InstallationTorque Tool, consistent installationcan be easily achieved. Refer toInstallation Instruction Sheet S500-12-1for details.

15 kV, 9 kv MCOV, 200A

Printed in U.S.A.

GENERALThe M.O.V.E.™ Surge Arrester combines metal (zinc) oxide varistortechnology in a premolded rubberelbow to provide overvoltage systemprotection in an insulated, fully shielded,submersible, deadfront device.

The arrester housing interface conforms to IEEE Standard 386™ –Separable Insulated ConnectorSystems. The arrester housing ismolded of EPDM insulating rubber,which provides deadfront safety in asmall, hotstick operable unit.

M.O.V.E. Arresters are used onunderground systems in pad-mountedtransformer and entry cabinets, vaults,switching enclosures and other instal-lations to provide shielded deadfrontarrester protection. They are designedfor use with 200 A loadbreak interfacesthat conform to IEEE Standard 386™

to limit overvoltages to acceptable lev-els, protect equipment and extendcable life.

CONSTRUCTIONThe rubber body is constructed of highquality precision molded peroxide-curedEPDM insulation and semi-conductivematerials.

The copper alloy probe and proberetainer are connected to the MOVblock stack via welded flexible tin-platedcopper leads. This ensures that thecolumn cannot be damaged duringinstallation and that a reliable currentpath to the MOV blocks is maintained.The disk column is composed of MOV disks bonded together withhigh-conductivity, silver-loaded epoxyto yield the most reliable electricalconnection and eliminate air voids. The#4 AWG flexible copper ground lead,which reliably carries current to groundduring voltage surges, is attached tothe housing by a brass magneformedend cap. The brass end cap providesa tight, weatherproof seal.

OPERATIONInstalling a M.O.V.E Arrester at the endof a radial system or at both ends of anopen point on a loop system providesexcellent overvoltage protection. Theaddition of a second M.O.V.E. Arresterat the mid-point on a rotatable feedthruinsert provides optimum protection.

600 A feeder circuits can be protectedwith elbow arresters installed on theCooper T-OP™ II Separable ConnectorSystems.

STANDARDSThe M.O.V.E. Arrester complies withthe latest revisions of IEEE StandardC62.11™ "IEEE Standard for MetalOxide Surge Arresters for AC PowerCircuits" and IEEE Standard 386™

"Separable Insulated Connectors forPower Distribution Systems Above600 Volts."

INSTALLATIONAll Cooper M.O.V.E. Arresters can beinstalled or removed from energizedbushings with a hotstick. No specialtools are required. The arrester isplaced on a 200 A interface by using ahotstick. Refer to Installation InstructionSheet S235-55-1 for more details.
