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 insulation ability decrease because of simple design and good waterproofness.
