    Cast resin transformer (Standard)
    It's characterized by good impulse withstand voltage with excellent insulation ability of epoxy resin and design of session dividing winding and has no fire or explosion risk by electric arc with its own self-extinguishing characteristics.   
         

    (1) Strong short-circuit force

    It has high durability for electric mechanical power, external shock and abnormal vibration on the disconnection because the coil of cast resin transformer is molded into Epoxy Resin in the high-degree vacuum. 

    (2) Fire Retardant 

    No fire risk and self-extinguishing ability using Epoxy Resin with excellent combustibility. 

    (3) Easy inspection and maintenance 

    Convenient maintenance without the high-level audemars piguet replica insulation ability decrease because of simple design and good waterproofness.
