HolloBus

What is a HolloBus?

HolloBus for Verticals

The latest patented design by STS, the system is intended to go higher up a building than anything else currently on the market. By a large difference as well. 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, 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, 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.

construction of the building, and afterwards as a permanent power source.

HolloBus Direct Replacement

THE HOLLOBUS SYSTEM by Superior Tray Systems

The HOLLOBUS system is the next step on the electrical power distribution “evolutionary” scale. It’s the natural replacement of the cabling and of the non-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 project’s requirements.

Advantages

  • SuperiorBus, Highbus and HolloBus can be used in the same project! They connect seamlessly to each other and to all power sources and switchgears.
  • They all have a 99-year life span.
  • They all are maintenance free for the first 40-50 years.
  • Our systems can be designed to provide any amperage and voltage drop.
  • Cost effective. In average, 50% less than any system on the market, giving the exceptional quality of our systems.
  • We adapt our concepts, designs and manufacturing process to fit your requirements, and not the other way around.
  • The loyalty and full support of STS team to our clients.
