What is a HolloBus?

The latest patented design by STS, HolloBus is a cable bus system intended to go much higher up a building than any other cablebus power distribution system currently on the market. Significantly higher. The technology is based on using a round hollow conductor. It is available with either a hollow copper conductor or an aluminum alloy conductor. The hollow conductors are coated with a special nonconductive polymer thus giving them a wet/dry rating and a low/med voltage rating. HOLLOBUS is fire stopped where it passes through walls or floors; and it’s water sealed where it passes through walls or floors.

HolloBus, like HIGHBUS and SuperiorBus cable bus systems, comes with 2-hour fire stops, where it passes through walls or floors. As well, the systems come with environmental seals. The rigid enclosure is made from aluminum. The support blocks are manufactured from a glass filled polymer.

The system has the ability to cope with a 1” +/- variance every floor (others buss duct 1” in 200’). The tap and joining enclosures use a flexible buss to connect 2 parts. The system can be supplied as either NEMA 1 (dry) or NEMA 3r/4x (wet).

HolloBus Direct Replacement

HolloBus, as its predecessor HIGHBUS, can be used as provisional power supply during the construction of the building, and afterwards as a permanent power source.

The latest patented design by STS is also designed to replace traditional bus duct with the 21st Century bus duct, which is never affected by water, by fire and by movement.

HOLLOBUS by Superior Tray Systems

The HOLLOBUS system is the next step on the electrical power distribution “evolutionary” scale. It’s the natural replacement of cabling and un-reliable bus ducts. Our system is intrinsically safe, flexible, reliable, and efficient. It is capable of ampacity and voltage (up to 15kV) customization, based on your project’s requirements.
