Founded in 1971…

Five employees used a $5,000 investment and followed their dream of producing the world’s finest quality substation power connectors. Now, with over 50 years of experience, hard work, and dedication, our company grew from a 2500 square foot building to a facility consisting of over 100,000 square feet – including office, production, and inventory spaces.  

We are an approved supplier to most major investor and government-owned utilities across North America; we also service contractors, distributors, OEMs, packagers, and other substation service providers. We offer a complete line of substation power connectors including bolted, welded, compression, and EHV applications. 

SEFCOR, Inc. is an American-Owned ESOP company that is ready to provide industry leading solutions for your next substation project. Contact us or your local sales representative for information on how we can best support you.
