Fuji Electric’s cast resin transformer works in Chiba was established in 1974, which became the first cast resin transformer works in Japan. Chiba works has produced over 90,000 cast resin transformers of which 3,000 units were exported to 55 countries all over the world.

Since the beginning of operation in 1998, Shanghai Fuji Electric Transformer has been awarded various certifications including ISO 9001 and has produced over 10,000 cast resin transformers.

Epoxy resin is safe against fire since it has self-extinguishing properties and is fire resistant.Our cast resin transformer passed the all tests of IEC 60076-11 in 2006.

A sheet coil and wound core construction minimize total loss remarkably, thus reducing the electricity charges and saving energy.

Cast resin transformer is made smaller and lighter comparing with oil-immersed transformer. Thus it can be installed in slim type cubicle, which minimizes the installation space.

No insulation oil is required, so maintenance and inspection are easy.

Cast resin transformer is manufactured with vacuum casting method using metal pattern, its resin layer is thick and the surface is smooth. Thus it has following excellent characteristics.

(1) Weight reduction The aluminum winding weights approximately one half of the 　 copper winding.

Vacuum-casting method realizes highly reliable, voidless molded winding with excellent partial discharge characteristics.

Void-less

All winding conductors are molded. They have remarkable humidity resistance which prevents insulation materials from deteriorating due to dust and dirt during operation.

Resistance to humidity and dust

Molded winging is highly resistant to secondary short-circuit fault and surface cracking.

Robust construction

Vacuum-casting process is carried out automatically with advanced customized facilities, to manufacture highly reliable molded winging.

High reliability

Molded insulated parts are fire resistant since they have self- extinguishing properties.

(3) Downsizing Sheet winding has high lamination factor.

(5) Surge stability Sheet winding is effective to reduce potential oscillation caused by surge voltage.

(4) High insulation reliability In case of sheet winding, the voltage between turns is only for one turn.

(2) Large mechanical strengthAluminum’s thermal expansion coefficient is close to resin, thus reducing thermal stress effectively.

Features of ProductFeatures of Product

Partial discharge freeWe have developed the materials, structures and manufacturing systems that realize excellent partial discharge characteristics.From the viewpoint of cast resin transformer’s reliability, the excellent partial discharge characteristics is the most important. Thus we have adopted the following stricter standard than any other standards.

The insulation of cast resin transformer is composed of resin-air composite insulation.The distributed voltages of individual transformer parts depend on their respective dimensions.Thus, appropriate dimensions for insulation are designed with electric field analysis of the individual parts of the winding including air space.

Molded winding composed of conductor and insulating material (e.g regin) is subjected to thermal stresses due to the difference in the thermal expansion coefficient between conductor and resin, and the thermal distribution in the winding block, where the winding temperature varies with the load fluctuation of the transformer.The stress value obtained in thermal stress analysis is used to design optimum winding structure for high crack-resistance of winding.

a) Routine tests: ・Measurement of insulation resistance ・Measurement of winding resistance ・Measurement of voltage ratio and check of phase displacement ・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

b) Type tests: ・Lightning impulse test ・Temperature-rise test ・Measurement of sound level
