About Us

Dear Valued Customer:

I am pleased to announce the establishment of Tiffin Insulators Company and welcome you to our website. Tiffin Insulators Company is rich with a long history in low voltage electrical insulators offering 34.5 kV and below applications (Low Voltage Assembly) and  C&I (Construction and Industrial and Pole Line Hardware) business dating back to 1894 when owned by Federal Porcelain until 1927.

After Federal Porcelain’s ownership, the Company had several owners throughout the 20th century, both private and public. Perhaps, one of the most well known names of the Company was Porcelain Products. The Company had this name for many years up until 2000. Most recently
, the name changed to Tiffin Insulators Co., LLC, now a privately owned US Company.

Tiffin Insulators Company will continue to service all of your Low Voltage OEM Assembly and C&I needs through the same dedicated staff with over 250 years combined experience.  Although our name has changed, our business has not; as we will continue to deliver quality products with the highest service level in the industry that you have grown accustomed to over the past 120 years. The Tiffin Insulators’ team looks forward to growing our business together for another 120 years.  Please browse around the website and check out our catalogs. As always, please feel free to contact me directly at any time and thank you for your continued business.
