Construction Industry Solutions

Before the 1980s, modern buildings primarily used reliable cables for electrical distribution. However, with the rapid urban development and the sharp increase in building power loads, the limitations of cable tapping and small capacity became increasingly evident. To address these challenges, busbar trunking systems—characterized by their large capacity and convenient branching—were widely adopted and popularized in various modern buildings as a superior alternative to traditional cables.

In contemporary buildings, a 10 kV dual-power supply with a single busbar section is commonly used, featuring automatic switching and mutual backup capabilities. Additionally, in some large and super high-rise buildings, 35 kV power supply lines are also widely adopted, utilizing either a direct drop or a two-stage step-down mode. Given that the primary loads in the construction industry include lighting, air conditioning, elevators, office equipment, and household electrical appliances—most of which are low-voltage and single-phase—the electrical systems in buildings often exhibit characteristics such as high harmonic distortion rates, large load fluctuations, and significant three-phase imbalance.

Drawing on years of experience in building electrical design, manufacturing, operation, and maintenance, our company offers comprehensive one-stop services, ranging from components and complete switchgear to system operation and maintenance management. This holistic approach effectively addresses the challenges of frequent procurement faced by our customers.
