Switchgea
Development Directions of Switchgear under New Quality Productive Forces
      Enhancing development quality and transitioning from the previous extensive economic growth model to intensive, high-quality development are equally crucial for the evolution of switchgear.         The switchgear industry suffers from severe homogenization, with low-quality products proliferating unchecked through simple repetition, competing solely on price and cost while neglecting quality. This approach consumes vast material resources without regard for sustainability, prioritizing short-term compliance over long-term reliability.

GWZC-9000 Drainage Pumping Station Automation System
Drainage Pumping Station Automation System—Forging a New Urban Flood Control Ecosystem
Drainage pump stations employ electromechanical systems for active water discharge, IoT and AI for precise regulation, and backup power for reliability. Digital twin platforms optimize decision-making with failure prediction and damage assessment. Each ¥100M investment reduces annual losses by ¥230M while saving 30% energy, as proven by Tokyo's flood defense system.
