Customer Benefits

 

Safe

The IP55 protection level provides water resistance and is dustproof. The busway remains highly reliable even in harsh environmental conditions, such as high humidity and dripping water. Delta has considered all aspects of the structure design.

• Installation: Attentive foolproof designs are available for every installation step
• Operation: Tool-less design for users to easily install plug-in units
• Compliant with IEC 61439 / UL 857

 

Reliable

The busway structure is an Aluminum housing. The busway adopts epoxy cast technology, which is filled and molded into one piece. Its advantages include:

• Minimizes risk from the stronger structure during lifting and assembly on data center sites
• Shield technology ensures optimum sequencing of the conductor. The integrated composite materials reduce EMC significantly and mitigate the interference to precision devices
• No maintenance is required

 

Efficient

The product design and installation uses many plug-ins and modular design concepts and is easy-to-use during the installation, operation and expansion phases.

Benefits of the continuous plug-in and modular design are:

• Unconstrained by space or location, the busway can be designed effectively and installed without professional technicians
• The plug-in unit adopts a modular design that can be expanded simply and quickly
• Customers can save time on waiting for materials if there is any change in design
• Users can save time and costs on installation, expansion, and alteration

Busway for Data Center Applications

With the recent wave of Big Data and IoT, data centers are responsible for more computing, communication and storage functions. In addition to the increase of their scope, the power density of a single rack cabinet has gradually increased. Effective space utilization is a great challenge for data center construction.

The Delta Cast Resin Busway System BR Series is exclusive for data center applications. Thanks to the epoxy insulation technology, it has a compact structure and size, as well as low EMC that allows it to overcome space limitations in server rooms. Data center designers can easily do wiring construction close to data cables without fear of an impact on their health due to low electromagnetic radiation.

In addition, the plug-in unit can be customized per customers’ requirement. It is flexible for use with different power supply systems of server racks. The plug-in unit also applies the flexible successive plug-in slots and is hot swappable. Therefore, it is not constrained by data center space. Customers can carry out expansion or distribution anywhere, which is very flexible.
