Selected SUNENG supply scope

SUNENG supplied selected electrical products and components for the Tianyu 110 kV outgoing works.

Project context.

The Tianyu project connects the 110 kV outgoing network to Tianyu 220 kV substation in Ji’an, Jiangxi. This phase covers the Yuqing I and II, Yufu, Yudong and Yushan outgoing works, together with local reconnections on the Hehong, Geshui II, Gezhu II and Gefu lines.

The completed works include 53 towers and poles. Single-circuit, double-circuit and shared three-circuit sections respond to the different route and connection requirements. The network diagrams explain the connections; the field photographs show lattice towers, steel poles, foundations and conductor arrangements along the routes.
