Modular Smart Substation for Yichuan LNG Energy Project — Yan’an, Shaanxi

Completed smart substation with transformer and prefabricated modules — Yichuan LNG Yan'an Zhongxin General

Zhongxin General delivered four prefabricated smart substation modules to an LNG energy project in Yichuan County, Yan’an, Shaanxi — dispatched November 10, 2025, two weeks ahead of the contractual deadline. The modular four-unit architecture (35kV switchgear, 10kV switchgear, secondary equipment, reactive power compensation) dramatically reduced on-site construction time and civil works costs. The main transformer is an SZ20-16000/35 OLTC unit — 16,000 kVA, 35kV/10kV — meeting GB 20052-2024 Grade 2 and EU 548/2014 Tier 2 energy efficiency standards. SCADA confirmed normal operation on April 26, 2026.
