Powering the City’s Arteries, Safeguarding Millions of Journeys
— Zhongyi Cable Supports the Safe Operation of the Beijing Subway
In a metro network serving tens of millions of passengers daily, the reliability and safety of the power system form the very foundation of urban mobility. Drawing on deep expertise in rail transit infrastructure, Zhongyi Cable has supplied specialized medium-voltage power cable solutions for multiple lines of the Beijing Subway.
To withstand the demanding conditions of subway environments—including humidity, confined spaces, vibration, and electromagnetic interference—we utilized waterproof armored structures and specialized insulation materials. These ensure long-term performance stability under constant vibration and temperature fluctuations. The cables’ excellent flame-retardant, fire-resistant, and low-smoke zero-halogen properties strictly comply with the highest fire safety standards for underground transit, providing critical time for passenger evacuation in emergency situations.
From Line 1 to the Capital Airport Express, Zhongyi Cable’s products are now deeply integrated into Beijing’s rail network, operating reliably every day to keep the city moving efficiently. We apply military-grade quality standards to deliver power transmission solutions that modern urban rail systems can truly depend on.
Our company’s main production includes High Voltage Cable, Low Voltage Cable, Electrical cables, and Control Cable, all made by factories we have known for many years.
