THE FUTURE OF ELECTRICAL POWER DISTRIBUTION

Wet/Dry

Worlds’ Only WET/DRY Rated Busway!

Revolutionary Systems Design

While this industry disruptor was designed to merge into current systems for early adopters; Hollobus Technologies Inc. will be THE name in distribution in years to come. The HOLLOBUS power feeder systems are intended for high-efficiency and trouble-free installation. Regardless of the length, shape, or obstacles the project has.

GEAR INTERFACE

Proprietary Bus Plug Connection - compliant with 110.14(c)

Purpose built; each Hollobus Gear plug is uniquely engineered for seamless compatibility with any gear type. Aligned exclusively with Superiorbus™ and Highbus™ to allow cablebus system sizing reduction by up to 50%. HOLLOBUS – while revolutionary – will also integrate with the complete line of STS products.

REVOLUTIONARY DESIGN

Hollobus’ advanced electrical power distribution system is both cost-effective, robust, and efficient. Designed to withstand water, seismic, and weather events, the HB ™ system is Fully Wet/Dry Rated, ensuring reliability in extreme conditions. As well as reduced power loss; Hollobus ™ decreases voltage drop by 25%.

Advantages of Hollobus

Cost Effective

Decreases power loss / volt drop by 25%. Hollobus is a stackable and expandable system allowing project flexibility like never before.

Robust Fail Proof

Can be used as temporary power during high rise construction in 10′ +/- 1″ cartridges. Purpose built.

Fully Wet/Dry Rated

Replaces both dated cabling and unreliable bus duct with FULLY wet / dry rated systems designed to survive water, seismic and similar events.

Patented Technology

Solution to 110.14 (C) cable bus connection requirement.

Easy Modular Installation

Modular cassettes in spans up to 45 feet. Pre-fabricated connections decrease installation time and costs exponentially.

Full 2 Year Warranty

Double the industry standard.

Hollobus Systems are Purpose Built

Safety First
Our system is intrinsically safe, flexible, reliable and efficient, as well as cost effective.. Capable of all voltage loads. First to market is our low voltage system. Certified to UL, CSA, NOM, and Management ISO 9001.

Fully WET/DRY Rated
The Hollobus system was designed to survive extreme weather events, whether it is energized or not. Our patented sealing technology allows water to pass through the system without any detrimental effects.
Built to NEMA 4 standards - not just Splash or Humidity tolerant; our system and enclosures will eradicate any concerns of water penetration failure.

Adjustable
Hollobus’ modular design is Sway friendly with our proprietary expansion/contraction system; modular and usable as temporary power during construction, Hollobus provides unparalleled quality and ease of installation.

COST EFFECTIVE
While being technologically and mechanically advanced; Hollobus will reduce costs. Increased efficiency reduces material costs, engineered for unparalleled ease of installation, reducing labor costs. TRULY a Win - Win

High Rise Specialists
Our patented technology allows ±1 inch of length tolerance per floor. 10 ft ±1”
This is especially critical for contractors, as floor height deviation is a common phenomenon in high-rise constructions.

Hollobus Systems

Up to 25% less voltage drop than traditional busduct
Up to 25% more length of the runs than traditional busduct
Operationally safe and durable
No temperature derating - Low temperature and naturally passive cooling*
Higher integrity and reliability (99-year structure lifespan)
Suitable for DC applications.
Vertical applications specifically designed to minimize the feeder count needed to power the building. Most buildings can be condensed to a SINGLE feeder when using Hollobus, saving you space, time and money.
Insulation plays the leading role in electrical distribution. Hollobus uses a durable, long-life, chemical and water resistant self-extinguishing epoxy/cross-linked polymer RTI 125C.

HB Plug: Gear Interface

The Hollobus gear interface is designed to meet the requirements of article 110.14(c) of the NEC – an historically overlooked requirement for derating at connections with cable bus; requires the use of a much larger cablebus system to be code compliant.

The interface allows a Superiorbus product to connect to the interface at a 90 deg C free air rating, and no more derating for your low voltage cable bus applications reduces system requirements by as much as half!.

The Hollobus interface connects to the gear connections with a flexible interface on one end and has a 90-degree C rated cable connection on the other end. These systems are designed to be dropped into place and bolted up with minimal labour.

HB Plug: Gear Interface

Expansion / Contraction Systems

This design is a High-Rise Tap Box; typically installed every third floor, featuring pre-configured load tap points to serve floors above and below.

Proprietary expansion and contraction systems accommodate multiple movement modalities, including sway, compression, seismic activity, and short-circuit events, effectively addressing any design challenge.

110.14(c) White Paper:
NEC Governance USA

110.14 Electrical Connections. 110.14(c) Temperature Limitations. 110.14(c)(1) Equipment provisions. 110.14(c)(1)(b) Termination provisions
Often overlooked in the past, more and more inspectors are aware and checking for derating compliance. This white paper—coming FEB 2025—will outline the scope of this code and the numerous ways it can be misread, leading to a possible non-energization. ALSO, the solution to safely comply without oversizing the cablebus — see HB Busplug—Gear Interface.
