Features: 
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.
