Electric Utility Grade Transformer

 An Electric Utility Grade Transformer from Niagara Transformer can take care of all of your power needs.  This transformer can come as a single-, double-, or three-phase transformer.  It can come in copper and aluminum allowing you to have it fit your specific needs.  This Utility Grade Transformer transfers the same amount of power that it receives.  However, it can increase or decrease the voltage or current levels that come in.  To keep power losses at a minimum, the transformer's system usually decreases the current level.  
Niagara Transformer can adhere to different county codes and regulations when installing and maintaining your new Electric Utility Grade Transformer.  Our skilled technicians have had years of experience and will install your new transformer efficiently and safely.
