What is Cable Bus?
Cable Bus is a power distribution system using multiple parallel conductors braced in a rigid enclosure. A standard range of Cable Bus systems are available from 600 volts to 218,000 volts and up to 10,400 amps. However, Cable Bus systems are adaptable and can be conducted to suit a customer’s particular requirements. Cable Bus can be used in a wide range of utilities, industrial and municipal projects which require a direct connection between a source and load.
Cable Bus is an electrical busway that consists of an assembly of fully insulated conductors mounted in a ventilated metal housing, utilizing cable support blocks to maintain cable phasing, spacing and short circuit protection.
Typical applications include: data centers, high risk construction, mining, industrial, wastewater treatment, backup generators, electrical substations, hospitals, and more.
What is a Superior Cable Bus?
SuperiorBus is a custom engineered Cable Bus power distribution system using multiple parallel conductors braced in a rigid enclosure. But due to the design and ingenuity, it is vastly more efficient and reliable than standard Cable Bus. Each conductor is not only insulated and fully continuous from source to load, it is evenly spaced inside a wet dry rated cable tray for maximum current and durability.
Standard SuperiorBus systems can carry 400 to 32,000 amps and beyond, with voltages from 208 volts to 218,000 volts. Systems can be designed for specific customer requirements. It is fully certified and easy to install, Superior Cable Bus can be any ampacity requirements for any situation.
As long as a cable at a voltage rating specified by a customer can be found, or made a Cable Bus system can be designed to suit their specific needs.
Cable Bus Power Distribution Systems Are:
– Cost Friendly –
In most electrical applications over 1,000 amperes, Cable Bus costs significantly less than non-segregated bus duct, cable in tray or conduit and wire systems. As ampacity and/or the cost of copper increases, the cost savings of Cable Bus over other systems is even greater. Copper prices continue to rise and remain higher than ever before. Less copper is used in construction when compared to competitive technologies which results in unparalleled cost savings.
Since Cable Bus is continuous there are no power losses from intermediate splices or connections. Cable Bus has a lower impedance and lower voltage drop because its conductors are properly phased, spaced and secured in a pre-engineered system. This reduces operating costs by providing long-term energy savings. The use of parallel conductors, combined with our free air rating, allows you to operate fully and efficiently with less conductor than would be called for with other types of systems. We cover Electrical Grids: What are Bus and Busbar? in this article.
– Reliable –
Due to having continuous runs of cable, faulty splices are prevented as well as wet dry rated. Cable Bus is proven and tested to be the most reliable system on the market.
Insulated conductors are designed and manufactured to remain unaffected by moisture and is ventilated for indoor and outdoor applications so that they can withstand the harshest outdoor environments. As a result, the parts are less likely to fail as does not require heater strips, filter breathers, or thermostats required by other power distribution technologies.
Each system’s phasing arrangement ensures optimal load balance. The system’s short circuit capacity is tested to over 100,000 RMS sym. amps. Polymer cable support blocks will not decay, rot or lose structural integrity from exposure to weather in order to provide maximum performance.
– Flexible –
As there might be some unforeseen obstructions during installation, Cable Bus accommodations can be made with field adjustments during installation. If the placement of equipment requires a different length of Cable Bus, additional product sections can be adjusted in the field quickly to satisfy the required length.
A Cable Bus is also designed to withstand the harshest environment – since the enclosure is ventilated and actually runs more effectively when wet and is not affected by water. Cable Bus can easily routed around unforeseen field obstructions like structural steel, piping, and other immovable equipment.
