Cast Resin Transformer is a new technical transformer. It is safer, quieter and saving environments more. You do not need to concern the problem of changing insulation oil, and have better specification than oil type transformers. We have great cooperation experience with Germen and French. In 1984, technical cooperation was made with ABB-ASEA LEPP, Germany, by using the original manufacturer's coil to assemble. In 1987, technical cooperation was made with FRANCE TRANSFO, France, to bring in advanced technology and automatic production equipment. Until 1999, there had been more than 7000 molded type transformers made by Shihlin Electric & Engineering Corporation functioning normally worldwide.

- High voltage coils
- Conductor material: Good quality copper (or aluminum) wire with high electrical conductivity is used.
- Winding: The unique technique by French FRANCE TRANSFO is applied. The voltage gradient of the coil is lower that makes the product have the higher coil life and voltage stress capability.
- Resin: SiO2 is added to the world top quality F graded resin to increase the resin thermal conductivity and reduce the thermal stress.
- Resin reinforcement: Fiber glass mesh is used on the outermost and the innermost layer of the coil to reinforce resin. Not only the resin thickness can be maintained but also the coil mechanics in absorbing short circuit can be increased.
- Casting: The Italian fully automatic resin casting system is applied. The whole process is under tight monitoring control to ensure the quality of each vacuum casting procedure.
- Low voltage coils
- Conductor material: Good quality aluminum (or copper) foil with high electrical conductivity is applied. This technique reduces electromagnetic force.
- Winding: High performance winding machine is used.
- Insulation materials: European high quality F graded insulation materials are applied.
- Core
- Silicon sheets: The sheets are made by using Japanese or European top class high permeability materials.
- Cutting: The German GEORG equipment is used for cutting the silicon sheets and the V-NOTCH and the STEP-LEPP shearing methods are also applied to sharply increase the iron core performance and reduce core noise.
