PEAK transormers rom Cooper Power Systems areuniquely designed to provide you with additional capability tomanage increased loads and temporary overload capacitywithout loss o lie expectancy when compared to mineraloil-lled transormer alternatives. Utilizing an advancedhigh-temperature insulation systemcomprised o thermallyupgraded krat paper, Envirotemp FR3 dielectric fuid,and an optimized core and coil designa 75 C AverageWinding Rise (AWR) PEAK transormer will result in a smallerootprint and a lighter unit capable o the same ratings as aphysically larger 65 C AWR rated unit. PEAK transormersare lled with the biodegradable alternative to transormeroil, Envirotemp FR3 dielectric fuid, a critical enabling

technology which extends transormer lie and raises reignition resistance. Combined, all o this results in a lowerlietime cost o ownership verses comparable fuid-lledtransormers.

Stretch Your System Investment With PEAK Transformers

A New Era in Transformer Design Standards

that Optimizes Overload Capacity andReliability in a Smaller Footprint

Cooper Power Systems introduces PEAK transormer technology or reliableelectric power voltage transormation with overload capacity to at least 112% insmaller, lighter units than comparable uid-flled transormers.

A Long History o Innovation

New technology has always driven changes in transormerdesign standards. With each revolution, the new transormertechnology exceeded the limits o previous designstandardsincreasing operating temperature, lie expectancy,and capacity. In 1956, Cooper Power Systems was the rstto design and sell the 65 AWR transormer. It wasnt until1964 that 65 AWR became the NEMA standard. Today,

the PEAK transormer design is driving the need or the newstandard, expected in all o 2012.

The new PEAK transormer is available in bothpole- and pad-mount designs.

Increased Overload Capacity

Utilities are now able to operate PEAK transormers beyond rated load to at least 112% to more precisely size transormebased on the period o peak demandwithout reducinginsulation lie.

Smaller kVA transormers perorm at the level o largertraditional units

Fewer transormers need to be installed on a network o same size since each PEAK transormer can handle morload more houses can be supplied per unit

Aging equipment can be replaced to add increased relia

to an existing system or long-term distribution planning

PEAK Transformers

Increased Overload Capacity

PEAK transormers are designed to accommodate heavier base loading, as well as peak loading greater than 100%, orextended periods o time without degrading the insulation system or the lie o the transormer.

Product or Service Description Here

Smaller, Lighter Transormers

When compared to traditional transormer operation at thesame kVA rating, the PEAK Transormer will be smaller andlighter. These units will use less material and ewer gallons odielectric fuid resulting in a better value, as well as loweringrelated costs o handling and operating the larger transormers.

Easier to handle and install

Reduces shipping costs

Reduces warehouse space needed

Banks o pole-mounted units require less space onutility poles

No need to upgrade utility poles and superstructure

when adding kVA

Increased Reliability

Moisture and thermal stress are the enemy o transormerreliability and lie. Longer lie contributes to systemreliability perormance. The capacity to load PEAKtransormers continuously at higher temperature andvarying loads without causing damage to the transormercontributes to better overall system reliability.

Insulation system lie is extended by a minimum othree to our times the standard ANSI lie o 20.55years, even at these higher operating temperatures

Filled with a bio-based dielectric fuid that is ULand FM Global recognized as a less fammablefuid, providing signicant enhanced re saety

Soybean oil-based fuid creates a barrier againstwater at the surace o the insulation making thethermal krat paper in the coil windings stronger andlonger lasting

Meets NEC standards or reduced clearancedistance without re suppression
