・Transformer Applications Designs
Fuji Cast-Resin Transformer can be applied to power transformers, distribution tansformers, transformers for static converter (such as VSD : variable-speed drive ).
・High-Rise Building Applications Designs
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.
・Wind Turbine Applications Designs
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)
Able to withstand AC 77kV Separate-source test voltage for 2000m above sea level site
3-phase 60Hz 2700kVA 0.69/34.5kV Insulation class H
Approximately 500units delivered since 2007
・Railway Applications Designs
Withstand cyclic load; excellent overload capability
Provision for harmonics of rectifier
; taking into account of the additional losses
Withstand 170kV Lightning impulse test voltage
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.
Partial Discharge Free
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
秒速牛牛官网 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.
