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
CSC-0883-345 **
