Our position as a global manufacturing leader enables us to offer our customers a cutting-edge incombustible transformer, which utilizes the superior insulation characteristics and the self-extinguishing characteristics of epoxy resin.
Fuji Electric customers rely on our cast resin transformers for a wide variety of applications and installations, with units in operation in various buildings, hospitals, public facilities, factories, and so on.
Fuji Electric's commitment to the environment can be seen in all of our products, and our high efficiency transformers are no exception, manufactured to help save energy and reduce CO2 emissions.
Fuji Cast-Resin Transformer can be applied to power transformers, distribution tansformers, transformers for static converter (such as VSD : variable-speed drive ).
Japan's largest capacity cast resign transformer at 17MVA, the units are installed on the 13th floor of a 41story building using the site-reassemble method. This technique allows for product installation in applications with size and weight restrictions.
3-phase 60Hz 13MVA(AN)/17MVA(AF) 22.0/6.6kV
Insulation class H
Deployment of Cast Resin Transformers
2008 - 3 units deployed to a high-rise building the city of Osaka, Japan.
The unit is disassembled following the factory test and is reassembled on-site following a verification test
Effective method to accommodate limitations on weight and size
Easy to replace the existing transformer without harming existing construction
Verification tests carried out on-site; measurement of voltage ratio
Optimum design results in compact size and lightweight transformers
Compact and light : Space saving with slip-on cable joint ⇒ Possible to install inside the shaft
High efficiency : 99.2% or more at rated power
Salt resistance : (*)ESDD 0.06mg/cm2
Vibration resistance : acceleration 0.5G (max.3G for TR body)

refer to IEC60076-11
3-phase 50Hz 2700kVA 33.0/2x0.59kV
Insulation class H
With protection enclosure IP21
Approximately 170units delivered to the railway substations in the Middle East in 2009
Our product is manufactured with vacuum casting method using a premium metal pattern, resulting in a thick resin layer with a smooth surface
Epoxy resin possesses self-extinguishing and fire resistant properties, making it safe in flammable environments
Fuji Electric's cast resin transformer successfully completed and passed all tests of IEC 60076-11 in 2006.
Void-less : Excellent partial discharge characteristics.
In order to maintain superior quality, Fuji Electric voluntarily adopted the following stricter standard:
All units are subjected to partial discharge test.
Voltage that is twice that of the operating system is applied to ensure safety
Partial discharge is less than 10 pC (Pico-coulombs intensity)
Cast resin transformers are also coated in high-vacuum chambers to reduce air and other gases in the resin that could produce partial earth discharges. In effect, they hermetically seal the transformer's core.
Measurement of insulation resistance
Measurement of winding resistance
Measurement of voltage ratio and phase displacement check
Measurement of short-circuit impedance and load loss
Measurement of no-load loss and current
Separate-source AC withstand voltage test
Induced AC withstand voltage test
Partial discharge measurement
Lightning impulse test
Measurement of sound level
Fuji cast resin transformers were officially certified after successful completion of all test items under IEC60076-11
This includes special test items and type test items by KEMA and CESI.
Certificate organization KEMA(Netherlands), CESI(Italy)
Japan's first manufacturer to obtain IEC60076-11 certification
Third party certification ensures objective confirmation of product compliance
Special test certification; climatic class C2 (crack resistance)
; environmental class E2 (moisture resistance)
; fire behavior class F1 (fire resistance)
; short-circuit test
