Unable tomaintain asbestos in arc chutes? Concernedabout the reliability of renewal and upgradingoptions being offered by others? Contemplatingtearing out the cubicles and starting anew?Don t! There is a practical is a committed engineering companythat has vast experience enabling cost-effectiveexpansion, upgrading and modernization ofmedium voltage power systems or compatible for match and line up withswitchgear using GE VERTICAL lift magne-blastbreakers, Powercon equipment provides a level ofprotection not previously available.

4 Among thebenefits:v AdaptabilityReadily expand present GE line-ups. Add on toeither end; indoor, outdoor, common aisle,protected some modernization approaches, Powerconswitchgear does not require the expense or floorspace needed for transition compartments. Buspass-throughs and connections are at the samelevel. Just remove the side panels and bolt Up To Date Equipment andTechnologyThere are no remanufactured or previously usedbreakers, structures or component partsemployed. Powercon SWITCHGEAR is all new, andbacked up by new equipment warranties InterchangeableKey parts of Powercon SWITCHGEAR areinterchangeable with original GE VERTICAL lift line-ups. For example, GE magne-blast breakers with ML-13 storedenergy mechanisms are directlyinterchangeable electricallyand mechanically with modernGE PowerVac VL VacuumCircuit Breakers.

5 As a result, yougain an important safety marginfor system availability Quality Assurance FromOriginal DesignsPowercon SWITCHGEAR units arebuilt from available originalengineering documentationwhich have been maintained onvertical-lift installations since theearly 1950 s added assurancethe new equipment will deliverdurability, reliability andperformance experienced withthe original VL breakers arecompletely design tested to and Cycloaliphatic Insulation Superior toPorcelainCycloaliphatic bus supports and/or thru-bushingsare used on all live conductors main bus, run-backs and PT connections. Cycloaliphatic is thematerial that has proven best for severeenvironments of high humidity, and contaminationsuch as encountered in refineries, paper mills andcoastal locations.

6 Of course Porcelain is Vacuum InterruptionFor power switching, the new equipment relies onVacuum Circuit Breakers. Among theiradvantages, the breakers perform numerous full-load switching operations with little deteriorationto interrupting contacts a major reason forcritical breaker maintenance. On average, thebreaker can be routinely maintained in one-thirdthe time required for magne-blast 4 of 8 PC-260 PROTECTION OPERATOR CAN SEEWhen lowering a breaker, the operator has completecontrol.
