Manufacturing Plants
Okonite is America’s oldest existing independent manufacturer of wire and cable.

Since 1878, we have been the foremost provider of quality insulated cable products to the electric industry. Since 1976, Okonite has operated under an Employee Stock Ownership Trust (ESOT) form of ownership.

Okonite’s manufacturing facilities include six plants across the United States, which have the capability to produce a full line of insulated cable products ranging from 300V to 345kV. Three of which can produce Okoguard EPR insulated cables offering our customers triple redundancy on many items.

At Okonite, we believe in continuous modernization and lean manufacturing programs which have resulted in a series of plant expansions and upgrades. These initiatives have added to our capacity as well as improved manufacturing efficiencies. We invite you to come see any of our facilities and get a first-hand look at what Okonite is doing to support the markets we serve.

Orangeburg SC Compound Plant
Orangeburg SC Compound Plant
Okonite manufactures all thermoset insulation and jacketing compounds in-house. We believe strongly that this is the only way to maintain the highest quality finished cable products. The Compound Plant is where we produce compounds that are integral to our Okoguard EPR insulation system. This modern facility uses a “closed loop” system for maximum cleanliness in insulation compounds.
