Product Description

General
Farady offers a complete range of distribution transformers designed to grant the reliability, durability, and 
efficiency required in utility, industrial, and commercial applications. Farady's liquid-filled transformers are 
manufactured in accordance with the most demanding industry and international standards.Compliance 
with important standards, from IEC to VDE, is a matter of course, just as much as the exclusive use 
of high-quality materials. Qualified employees implement the demanding standards in daily practice.
