Composite Technology Corporation has completed its second ACCC conductor transmission line in Mexico.
The 22 kilometre Hawk ""Ciudad del Carmen - 166 SLT 1002 Compensacion y Transmision Noreste-Sureste"" line was installed in December and was recently successfully energized.
ACCC conductor consists of a hybrid carbon and glass fibre core which is stranded with trapezoidal shaped aluminium strands. The high strength structural core carries most of the conductor’s mechanical load, while the fully annealed aluminium strands carry all of the conductor’s electrical current.
By selecting and installing ACCC Hawk conductor, the Comision Federal de Electricidad (CFE) was able to upgrade the existing 115kV line to 230kV without modifying or replacing any of the 11 lattice steel towers spanning the Gulf of Mexico from the mainland to an island.
Two key issues considered by the utility in this project were sag clearance for boating safety and corrosion due to the harsh marine environment. ACCC conductor was selected due to the non-corrosive nature of the ACCC composite core and to avoid the expensive cost and difficulty of replacing structures over the waterway, while increasing CFE's capacity with less sag at higher temperatures.
John Brewster, President of CTC Cable, commented, ""After almost two years of study and preparation, we are pleased with the successful completion of the Carmen project. We are optimistic about the prospects for the use of ACCC conductors in Mexico and we look forward to continued cooperation with CFE and COBRA.""
