YueBiao New Compact Busway
It combines the best of sandwich and air-insulated designs, fixes the usual weak spots, and performs on par with the top global brands—your go-to replacement for big-name imports.
High value, high margin, bid-winning edge!
The shell is one-piece, high-grade aluminum alloy: light, sleek, and corrosion-proof. Deep-fin side plates double as heat sinks, so it runs cool, stays stiff, and handles long spans without breaking a sweat—rock-solid for decades.
Advantages of Compact Busway
The chief benefit of dense-type bus duct is rapid heat dissipation; hence most modern designs use aluminum alloy shells for their superior thermal conductivity. A basic electrical rule applies: the same conductor (identical material, cross-section and insulation) performs very differently at different ambient temperatures. Rising temperature reduces current-carrying capacity, and that reduction in turn drives temperature still higher—a vicious cycle. Thus effective heat dissipation is critical to the reliable performance of any bus duct.
