The only OSHPD approved, liquid-filled
transformers rated up to 10,000 kVA for
applications in seismic zone areas
Seismic solutions from Cooper Power Systems
Cooper Power Systems now offers liquid-filled substation and pad-mounted
distribution transformers from 45 to 10,000 kVA with approved certification from the
California Office of Statewide Health Planning and Development (OSHPD) organization.
Hassle-free qualification in seismic zone areas with OSHPD certification and anchorage
pre-approval with Cooper Power Systems transformers
What is OSHPD and how will it affect electrical
construction projects?
Pictures from the third-party test facility are shown below:
One of many branches of OSHPD regulates the design and
construction of healthcare facilities in California to ensure
they are safe and must remain functional in the event of a
natural disaster – including earthquakes. The organization has
significant influence over worldwide seismic standards and
the International Building Code (IBC). The intent is to provide
reasonable assurance of seismic performance to avoid serious
injury, loss of life, loss of function, and minimize repair cost in
critical facilities.
OSHPD released new requirements effective January 1, 2011.
These requirements affect California facility construction
projects today, but has the potential to expand beyond
California to seismic construction sites throughout the US.
Qualified projects will need two forms of approval: product
approval and anchorage approval prior to installation.
Cooper Power Systems has both and can furnish necessary
documentation with our offering.
Special seismic certification pre-approval
(OPS-0121-10)
For product approval, Cooper Power Systems passed the test
to remain operable following a significant seismic activity. This
includes product, components, supports, and attachments.
Seismic qualification is granted by passing an international,
IBC recognized, shaker table testing standard. Possessing
this certification assures end users the product is compliant for
OSHPD regulated projects. Our design is qualified for a spectral
response acceleration at short periods (Sds) level of 1.93 for an
array of transformer sizes and accessories.

Anchorage pre-approval
(OPA-2557-10 through OPA-2562-10)
Product approval is only one part of the qualification needed
to comply with OSHPD. You also need anchorage approval.
We’ve done the work for you.
Cooper Power Systems can provide certificates that fulfill
OSHPD requirements and eliminate the need for a third party
consultant or site inspection of the anchorage layout. We’ve
determined the number of holes and proper anchorage
provisions in our designs with final calculations validated and
stamped by a licensed California structural engineer.

Cooper Power Systems transformer standard designs are capable of withstanding a
significant seismic event. Our standards include:
• Sturdy electrical framework held within a sealed, multi-point anchored tank
• High-efficiency rectangular core designs coupled with compact and electrically
balanced coils
• Rigid core and coil assembled in a well-built mechanical frame
• Accessories firmly mounted to either the interior or exterior of the tank body
Features
•Designs shaker-tested for structural and functional integrity
•Designs interpolated to validate similar sizes in between maximum and
minimum tested
•Designs complete with pre-determined anchorage provisions and bolting
recommendations
Benefits
• Cooper Power Systems transformers can cover nearly all locations as designs
are compliant to Sds 1.93, seismic specifications
• Select from a host of customized designs with the industry’s largest array of
transformer sizes and accessories available to integrate with the transformer
• Save time and approximately $2500/unit by avoiding engineering consulting fees
by having pre-approved anchorage design / recommendations (OPA-2557-10
through OPA-2562-10)
Specify your transformer with Envirotemp™ FR3™ dielectric fluid
Envirotemp™ FR3™ fluid is the most advanced material used in the construction
of transformers today. Because of its unique interactions with solid insulation and
moisture, this bio-based fluid enables insulation systems to age more slowly than
traditional dielectric coolants. Users can accelerate their return on investment
by specifying 75 °C average winding rise (120 °C hottest spot temperature)
transformers while maintaining the transformer’s current expected life. This enables
the smallest footprint transformers available.
Envirotemp™ FR3™ fluid is the most environmental friendly dielectric coolant
available today. It is readily biodegradable, and is non-toxic. The fluid is essentially
carbon neutral per the National Institute of Standards and Technology (NIST) life
cycle impact analysis Biobased for Environmental and Economic Sustainability
(BEES v4.0e) report.
With a flawless fire safety record, specifying Envirotemp™ FR3™ fluid delivers a step
function increase in mitigation of long term liabilities. Envirotemp™ FR3™ fluid-filled
transformers meet the National Electric Code (NEC) for indoor installation without
users incurring expenses associated with fire mitigation equipment or fire vaults.
Improved safety, reduced long term liabilities, and faster return on investment, results
in Envirotemp™ FR3™ fluid being recognized as a best-in-class dielectric coolant.
