CLASSIC CONNECTORS USA, LLC. (CCU) a Mansfield, OH based manufacturing company is licensed by CLASSIC CONNECTORS, INC.

At Classic Connectors, our flagship ClampStar® technology is a premier Grid-Enhancing Technology (GET) that provides a permanent life-extension solution for overhead conductors. ClampStar units are engineered electrical and mechanical shunts designed to reinforce critical connection points—such as splices, suspension clamps, and deadends—without requiring power interruption.

Transmission networks face a massive bottleneck: while HTLS conductors such as ACSS can handle high loads, aging legacy connectors overheat and fail. ClampStar acts as a permanent electrical bypass, instantly unlocking latent capacity and allowing existing lines to safely operate at continuous temperatures up to 250°C. This “speed-to-market” solution is critical for meeting soaring AI data center power demands and strict N-1 reliability mandates without the 5-to-10-year delays of building new transmission lines.

Furthermore, ClampStar plays a vital role in proactive wildfire mitigation by eliminating the high-resistance connections that cause catastrophic wire-down incidents in dry environments. Our specialized Conductor Repair Units (CRU) also permanently restore full mechanical and electrical integrity to lines suffering from gunshot damage, lightning strikes, or severe wear. Additionally, our high-performance CST tap connectors safely upgrade lower-performing clamps to deliver enhanced system reliability.

By bypassing thermal hardware limitations, ClampStar allows utilities to drastically reduce congestion costs, harden the grid, and safely maximize capacity.
