Compact Busduct

The stable operation of a compact (sandwich) busway system relies on precisely matched core components and high-quality materials. Its core components mainly include conductors, insulation layers, housings, and joints, which work together to ensure efficient and safe power transmission.

As the core of power transmission, conductors are made of high-purity electrolytic copper or aluminum alloy through precision processing into copper or aluminum bars. They feature high current-carrying capacity, low resistance, and low power loss, and can be customized in cross-section according to different power requirements to suit various industrial and building applications.

The insulation layer is critical for safety protection. It uses heat-resistant, highly flame-retardant polyester film or epoxy resin to tightly wrap the conductor surface, effectively isolating phases and preventing contact between conductors and the housing, thus eliminating risks of electric leakage and short circuits. It also offers excellent aging resistance to extend the service life of the product.

The housing is integrally formed from cold-rolled steel sheet or aluminum alloy, treated with pickling, phosphating, and plastic spraying, providing corrosion resistance and impact resistance. Some upgraded models adopt an I-shaped structure with additional cooling fins, which significantly reduce operating temperature rise.

Joints are key connecting components. They use precision fittings of the same material as the conductors, combined with anti-loosening locking structures to optimize contact performance and reduce contact resistance, ensuring stable connections. They also provide good electrical conductivity and sealing performance, suitable for splicing busway sections of different lengths to guarantee overall transmission efficiency.

Compared with air-type, enclosed-type, and cast-resin busducts, sandwich-type busducts offer significant advantages in structure, performance, and practicality. Featuring a tightly arranged conductor structure, they are smaller in size and lighter in weight. With the same current-carrying capacity, they occupy less space and allow more flexible and efficient installation, making them ideal for space-limited applications such as high-rise buildings, data centers, and industrial plants.

In terms of electrical performance, sandwich-type busducts have uniform insulation spacing and shorter heat dissipation paths. Coupled with an optimized housing structure, they produce lower temperature rise and less power loss during operation, ensuring greater energy efficiency and stability over long-term use. Unlike air-type busducts, they avoid poor heat dissipation caused by insufficient internal air convection. Compared with fully cast-resin busducts, they eliminate the disadvantages of slow heat dissipation, difficult maintenance, and high cost. Meanwhile, the joints adopt an anti-loosening design with low contact resistance and stable conductivity, effectively reducing failure risks. The housing provides strong protection and mechanical strength, with good corrosion resistance and deformation resistance, enabling a wider range of application environments.

Overall, sandwich-type busducts combine high current-carrying capacity, efficient heat dissipation, compact structure, easy installation, and high cost performance. They are the preferred solution in modern power distribution systems with stronger versatility and more prominent comprehensive benefits.
