Analysis of critical field procedures for power HV overhead transmission line splices installed after restructuring of Brazilian electrical sector

The electricity transmission system lines in the Brazilian re-structured market is the subject on this work. Also are studied transmission lines field procedures considering economy and reliability of ACSR (Aluminum Core Steel Reinforced) cables and compression splices. The work describes compression splices field surveys with suppliers and users concessionaires and also suggest some procedures and inspections routines to improve system reliability.
