State Grid builds 296-meter high transmission tower in Brazil, highest in South America

Date: 29 Mar 2012

The Brazil 500KV Spanning-Amazon Transmission Project, constructed by Zhejiang Electric Power Transmission & Transformation Corporation, has officially started assembling the 296-meter-high tower, the highest in South America.

Being apart of SGCC’s “going global” strategy, the project combines China's elite forces and sophisticated equipment in the transmission tower construction field. The Brazil 500kV Tucurui-Xingu-Jurupari transmission line is 508.33 kilometers long and, after it is completed, will be able to transport about 4 GW power across the Amazon River to Manaus and Macapa. The span over the Amazon River is the main component of this project and is co-constructed Zhejiang Electric Power Transmission & Transformation Corporation, China Cable Corporation, and Zhejiang Shengda Steel tower Co., Ltd. Zhejiang Electric Power Transmission & Transformation Corporation is responsible for erecting the transmission tower and the stringing construction of the large span.

Reportedly located in Almerim, the large span will also need the construction of 2 steel pipe towers with a base height of 296 meters, each weighing about 2500 tons. The large-span conductors use 4x779.4 mm special high-strength aluminum stranded lines with a steel core and has a main span of 2148 meters and a span of 3908 meters in the strain section.
