ClampStar®

ClampStar® is an engineered electrical and mechanical shunt that, along with proactive maintenance practices improves safety and prevents unplanned outages.

ClampStar is the industry’s only PERMANENT life extension solution for virtually all overhead conductors.

Increasing power flows on some of the oldest lower-voltage circuits, especially during emergencies has put significant pressure on a power grid that was built mainly to serve local markets.

ClampStar is necessary to help bring the power grid up to a level of acceptable physical soundness and reliability.

Corona Shields
CSC-0883-230	Corona shields are generally required for applications above 138 kv. The appropriate shielding is obtained by combining the ClampStar unit number with the highest anticipated system voltage. Example: CSC-1108-230 designates shielding for corona free performance of CRU/CSF/CSR-1108 units installed on a 230 kv system. **Same shield is used for 230 and 345 KV applications
