HighBus Is The Leading Manufacturer Of Cable Bus Systems For High-Rise Buildings
HIGHBUS is a custom-engineered modular cable bus system designed for vertical power distribution in high-rise buildings. It integrates seamlessly with other STS systems, offering the longest industry warranty (minimum two years). With advanced features such as water-resistant components and seismic adaptability, HIGHBUS ensures efficient, durable, and flexible power distribution that meets the unique needs of modern construction projects.
For Complex High-Rise Power Distribution Projects
The HIGHBUS systems is engineered for thermal contraction-expansion and building sway with fewer components and connection points allowing for rapid trouble-free installation with zero misalignment issues.

☑ System Balance
Properly balanced systems ensure equal impedance between conductors within each phase of a cable bus system. This ensures the maximal current carrying capacity is achieved.

☑ Safety
Cable bus uses fully insulated power cables from source to load. Shock absorbers protect damage to cable insulation during short circuit. The entire system is protected by a welded aluminum enclosure.

☑ Reliability
Cable bus is 100% maintenance free and has a long service life. There are no conductor splices to torque and monitor.

☑ Quick Drawing Layout
All systems are supplied with complete layout drawings to ensure an efficient installation. Based on a customer supplied centerline sketch, layout drawing packages can be generated with in-house written software routines.
Optimized Efficiency
HIGHBUS provides significant space and cost savings compared to traditional bus duct systems. By reducing the inductance and improving voltage drop by up to 50%, HIGHBUS ensures superior power distribution efficiency. Its innovative design uses parallel cables to form phases and neutral, minimizing electromagnetic interference and improving overall system performance. Additionally, it allows for easier installation and a more compact footprint, reducing the need for large feeders and the associated costs.


Water Protection
HIGHBUS is engineered to withstand water events, including flooding up to 12 inches. Its waterproof floor flange water dam and patented sealed enclosures protect cable terminations from water damage, making it the only system that can function as both a provisional and permanent power supply. Designed to operate in wet and dry conditions, the system reduces the need for costly replacements due to water damage during construction and the building’s lifespan. The inclusion of firestop pillows at building penetrations further enhances the water-resilient capabilities of HIGHBUS.
Reliabililty & Durability
The HIGHBUS system is designed for maximum reliability and durability. Its permanent conductor connections, which use two bolts per cable (surpassing the industry standard of a single friction joint), ensure long-lasting performance. The system is maintenance-free and can be used as provisional power during construction, continuing to serve as the main power supply after completion. Furthermore, the system’s modular design allows for easy installation and trouble-free operation, minimizing downtime and operational disruptions even in extreme conditions.


Provisional Power
HIGHBUS serves as an ideal provisional power source during construction, with the ability to operate in both wet and dry conditions. It can be installed as early as the 7th floor of a building’s construction and continue to serve as the permanent power solution once construction is completed. The system’s modular design, which includes pre-configured terminations and tap boxes, allows for quick setup and flexibility during the early stages of a building project, while maintaining reliability as the building’s primary power system.
Engineered Excellence
The HIGHBUS system showcases superior engineering, integrating advanced design elements for seamless performance in high-rise construction projects. Engineered for vertical power distribution, it features custom lengths for specific floor heights and systems designed to carry up to 4000A per phase at 600V. The system is built with minimal components, reducing installation complexity and space requirements. Additionally, it is equipped with environmental seals and firestop technology, ensuring resilience against water, fire, and seismic challenges. Manufactured by Superior Tray Systems with decades of experience, HIGHBUS reflects the company’s commitment to precision and innovation.
