Precision engineering for the MV grid.
Shanghai Zhongce Electric (ZC Electric) — a KAM PAU company. Small yet refined. Specialized in cubicle GIS and core components, 35 kV and below.
Empowering global power grids.
Focus on MV / HV switchgear — small yet refined, beautiful yet specialized.
Delivering safe, reliable and sustainable electrical components and full-set solutions.
Founded in 2016, ZC started in installation and maintenance, then built independent R&D for vacuum circuit breakers, disconnectors, operating mechanisms and complete C-GIS. We manufacture in Shanghai and Yangzhou. Sales offices: Hong Kong (a subsidiary), plus Malaysia and Houston — both wholly owned by the Hong Kong company. Houston trades as Nexus Power Supply (NXPWR).
