Recently, the Wenzhou Development and Reform Bureau approved the Wenzhou Leqing Yannan 110 kV Transmission and Transformation Project. The construction site of this project is located in Furong Town, Yueqing City, with a total static investment of 90.21 million yuan.

Yannan 110kV Substation New Construction Project

Substation Main Transformer Vision 3 × 50MVA, construction 2 in this phase × 50MVA main transformer, using 110/10kV on load tap changer, with main transformer tap changer 110 ± 8 × 1.25%/10.5kV, wiring group YNd11, impedance voltage 17%. Three 110kV long-term outgoing lines, two in this phase; There are 36 10kV long-term outgoing lines and 24 in this phase.

The 110kV electrical main wiring adopts internal bridge+line transformer group wiring in the future, and internal bridge wiring is used in this phase; 10kV prospective adopts single bus four section wiring, and this phase adopts single bus section wiring. Vision Installation 3 × 3600+3 × 4800kvar capacitor bank, 2 installed in this phase × 3600+2 × 4800kvar capacitor bank. Three sets of arc suppression coils will be installed in the future of the substation, and two arc suppression coils will be installed in this phase × 630kVA.
