The HighBus is designed to meet the unique challenges of electrical distribution in high rises, the revolutionary HighBus system is the latest iteration of the SuperiorBus. HighBus is a custom-engineered, modular cable bus power distribution system designed for use in high rise apartments and office buildings. This innovative system is durable, intrinsically safe, and reliable. It is also more cost-effective than electrical distribution systems currently on the market.

Pro Tips

  • Cost-effective
  • Balanced system with verified phase arrangement
  • Flexibility tolerates building sway
  • Water dam and watertight seals endure up to 12” of water flooding
  • Reduced footprint by up to 50% compared to standard bus duct


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. The system provides numerous advantages including substantial cost savings on labor, maintenance, and space. Furthermore, the HolloBus system minimizes power loss and voltage drop. The system is designed around hollow conductors.

The HolloBus technology is intended for high-efficiency and trouble-free installation, regardless of the length, shape, or obstacles. It can be used on its own or can be converted to the HighBus system for specific rating requirements. Additionally, it can be hooked up to SuperiorBus, for tapping off to auxiliary gear around complex architectural features and through walls. All three systems in the same project!

Pro Tips

  • Cost-effective
  • Fail-proof Fully wet/dry rated
  • Easy modular installation
  • Patented technology
  • Two-year full warranty
