Arizona is undergoing rapid infrastructure growth. At Harbor Energy Solutions, we are ready to support this growth with custom-engineered cable bus systems that deliver unmatched reliability, safety, and cost-efficiency.
As the independent U.S. representative of Superior Tray Systems (STS), we provide high-performance power distribution solutions that meet the unique requirements of industries throughout the state. From commercial skyscrapers and data centers to hospitals, naval installations, and renewable energy projects, Harbor Energy Solutions is the go-to provider for cable bus systems in Arizona.
Why Cable Bus?
Cable bus is a robust power distribution system that uses multiple insulated, continuous conductors housed in a rigid enclosure. Unlike traditional bus duct or cable tray systems, cable bus is custom-engineered for each project. It handles high amperage loads (from 400A to 32,000A) and voltage ranges from 208V up to 218kV. It is maintenance-free, scalable, and can be installed indoors or outdoors.
Its modular nature and adaptability make it ideal for Arizona’s diverse environmental conditions and urban density challenges. Whether it’s a wind farm on the Columbia Plateau or a high-rise in downtown Seattle, our cable bus systems deliver.
Why Harbor Energy Solutions?
Harbor Energy Solutions brings a rare combination of technical expertise, product access, and on-the-ground experience in electrical project management, layout, and installation. Our exclusive partnership with STS, a leading engineering and manufacturing firm, strengthens our ability to deliver state-of-the-art solutions.
When you work with us, you get:
- Full collaboration with STS engineers
- Custom layouts and volt drop analysis
- CSA, UL, NOM-certified systems
- Installer training and manufacturer support
- Pre-configured systems to simplify installation
We don’t just sell a product. We manage the process from concept to commissioning.
Serving Arizona’s Diverse Industries
Cable bus systems are suited for nearly any environment requiring stable, high-capacity power distribution. Here are just a few of the sectors we serve in Arizona:
- Data Centers With the explosion of cloud computing and AI, Arizona has become a hub for data centers. Cable bus provides high reliability, low voltage drop, and a minimal footprint—perfect for data-heavy environments.
- Hospitals From Seattle’s medical campuses to regional facilities, uninterrupted power is non-negotiable. Our systems include redundant configurations, environmental seals, and are watertight and fireproof.
- Marine Installations Cable bus systems are ideal for naval yards and port facilities across Puget Sound, thanks to their corrosion-resistant enclosures and robust design that stands up to marine environments.
- Industrial Sites and Energy Projects The hydroelectric plants, wind farms, and heavy industries of Eastern Arizona need systems that can handle extreme loads and weather. Our ruggedized cable bus systems are designed for exactly these conditions.
- High-Rise Construction For the booming real estate sector in urban areas, our HighBus system is a game-changer. It fits into compact vertical shafts and reduces voltage drop by up to 50%, solving a major problem in high-rise electrical design.
SuperiorBus and HighBus: Our Flagship Systems
SuperiorBus is the core offering from STS—a custom-engineered cable bus system for general use in high-capacity, high-reliability settings. SuperiorBus systems come with:
- Ampacities from 400 to 32,000A
- Voltage ratings from 208V to 218kV
- Insulated, continuous conductors
- Custom layouts to match building geometry
HighBus takes this a step further, designed specifically for high-rise residential and commercial buildings. Benefits include:
- Modular sections for quick installation
- Integrated fire stops and waterproof seals
- Pre-configured terminations
- Up to 4000A per phase at 600V
- Use as temporary and permanent power source
HighBus reduces costs over the lifecycle of a building and simplifies both design and construction.
From Blueprint to Reality
One of the standout advantages of working with Harbor Energy Solutions is our ability to turn your vision into a finished system. Whether you start with a full blueprint or just a basic sketch, our collaboration with STS allows us to take your idea and create a full electrical design package, including:
- Physical layouts
- Electrical calculations
- Voltage drop simulations
We follow your project through every phase: design, fabrication, shipment, installation, and final testing.
Proven Certifications and Standards
Our systems meet and exceed safety and performance standards. STS products are CSA, UL, NOM, and ISO 9001 certified. We also provide the only CSA/UL-certified ventilated cable bus/cable tray enclosure available today. In a state like Arizona where regulation and safety are paramount, these certifications are more than checkboxes—they’re your assurance of long-term reliability.

Training, Support, and Long-Term Partnership
Choosing Harbor Energy Solutions means entering into a partnership, not a transaction. We work alongside you and your contractors to ensure success, offering:
- On-site or virtual installer training
- Direct access to manufacturer engineering staff
- Custom design support and product selection analysis
- Fast and efficient logistics planning
We stand behind our systems and the people who install them.
Energy-Efficient, Cost-Effective, and Built to Last
Cable bus systems offer 20-30% cost savings over traditional systems. That means lower capital expense and reduced operating costs. These savings come from:
- Faster installation
- No need for cable trays or conduit
- Minimal maintenance
- Longer life cycle
When it comes to ROI, cable bus simply outperforms.
