What is the Busway system?

Busway system, also known as the conductor bar system, is used to replace electric cables at construction sites. The system is built in the form of a hard-sheathed rod, using an internal copper or aluminum core to conduct electricity. The outside of the busbar is covered with insulating material to increase safety compared to using traditional conductors.

The design of busbars in a building can have many types of guide shafts, but in general there are 3 types as follows:

• Connection from transformer to main distribution cabinet (LV Panel) (horizontal rise)
• Connection from generator to main distribution cabinet (LV Panel) (horizontal rise)
• Busbar shaft from the distribution cabinet to the floors (vertical rise)
• Also possible forks (using T connections)

The structure of Busway

• The cover is made of high-grade steel and aluminum to reduce hysteresis and loss due to eddy currents when large currents are passed. The cover is coated with ANSI 49 gray epoxy for protection against static electricity, rust and corrosion from acids and other chemicals. In addition, the cover is sealed, not vented to avoid external impacts and dust.
• Conductors are made of high grade copper with purity up to 99.9% cold drawn, silver plated or aluminum. This part has high conductivity for the purpose of ensuring the best conductive process, suitable for each design capacity. In addition, the joints or contact points are copper-aluminum bimetallic layers using molecular fusion technology (Molecular Fusion). This helps to ensure rigidity when the product is installed.
• The insulator is equipped with polyester film grade B 1300c DuPont Mylar or F 1550c Dupont Melinex, providing effective insulation, avoiding electrical leakage due to environmental influences, endangering human life.
• The racking system is designed and installed based on the manufacturer's standards. In particular, the feeder and plugin guides when installed indoors have a maximum distance of 30m when installed horizontally, 5m when installed vertically and 1.5m when installed outdoors for both cases.

Advantages of Busway system

Busway is designed with diverse configurations and rich designs to increase the aesthetics of the building. The electrical conductors after installation are arranged neatly in each block. This helps to facilitate monitoring and maintenance when something goes wrong. In addition, the conductor bar makes construction and installation more flexible thanks to the connector and coupling sizes designed based on certain standards.

Busway has a large electrical conductivity, can be up to 6300A, 7500A and withstands short-circuit currents higher than normal conductors, thanks to the core made and manufactured from pure copper. At the same time, Busway also helps to save maximum electricity. The couplings are capable of conducting electricity with a standard distance of 3m, so that the potential for voltage drops is lower than when using traditional power cables.

The heat dissipation and durability of the conductor are great thanks to the cover made of metal, which protects the system from external forces. In particular, the conductor bar is a product manufactured according to IEC 60529/IEC 61439-6/IP54 standards, so the contractor can be completely confident about the product quality.

Considerations when installing Busway system

• Avoid water or any other liquid - spray on the guide.
• Avoid strong impacts that damage the Busway cover, causing distortion and scratches. Specifically, do not drill, hang, anything to the surface of the system, do not swing or use the Busway system as a fulcrum.
• Do not disassemble, adjust or change parts of the Busway system without consulting the supplier. Arbitrary deception can cause serious incidents and damage not only to the works but also to human life.

With the motto "We care for you", Taisei VN is constantly improving and developing service quality to bring customers the best experience.
