Empresa de Transmisi\u00f3n El\u00e9ctrica S.A. (ETESA) has just started the construction on a critical capacity upgrade to an existing double circuit 230 kV transmission line in David City, Panama. The project is supported by\u00a0Elecnor, an EPC firm.<\/p>\n

ETESA was able to use all 220 of the existing metal lattice suspension and anchor towers without requiring any structural upgrades by using high-performance, high-capacity ACCC conductor. The conductor which is developed and produced by CTC Global, is available through a number of authorized manufacturing partners,<\/p>\n

ETESA selected 23.55 mm 2 Dove size ACCC conductor to replace ACAR conductor on the Mata de Nance – Veladero line that had been in service for many years. The transmission line, located in the Province of Chiriqui, comprises a 230 kV transmission line and double three-phase circuit, which\u00a0starts in the existing S\/E Mata de Nance Substation, located in the town of Mata del Nance, and its termination in the existing Substation S\/E Veladero in El Veladero. The 84.5-km project includes both river and mountain crossings with a 37-km continuous section of suspension structures only.<\/p>\n
