Cable management systems that utilize cable trays instead of conduit create flexible wire support solutions that make cable easier to access, mark and remove. Cable tray systems are made of steel, aluminum and fiber-reinforced plastic structures that are available in a number of structural parts that include ladders, channels, ventilated, mesh single rail and more.
Cable trays are a part of a planned cable management system to support, route, protect and provide a pathway for cable systems, according to OSHA 1910.399. These systems support cables across open spans and are treated as a structural component of a facility’s electrical system.
A reliable cable management system is an investment, but when it’s well planned, it can save you time and money while keeping your facility power systems reliable.
CONSIDERATIONS FOR BUILDING A RELIABLE CABLE MANAGEMENT SYSTEM
LOCATION
What elements will your cable management system be exposed to? Cable trays can be rated for outdoors, indoors, corrosive and classified hazardous locations, and areas with high electrical noise and vibration, according to OSHA SHIB 01-16-2008. Cable tray systems are popular in hazardous locations, but when improperly used and exposed to flammable or combustible gases, vapors and dust could result in explosion. Always check the National Electric Code (NEC) compliance.
MATERIAL
Material type is also important depending on the location. Aluminum is lightweight, can handle heavy loads and is corrosion resistant in most environments. Steel works great in indoor and outdoor locations, with the exception of saline environments. Salt will corrode the steel over time. Stainless steel is great for high- and low-temperature environments. It works well in areas where contamination and appearance are a concern. The last material option for cable management systems is fiberglass. Fiberglass is best for extra corrosive and harsh environments.
COMPONENTS
Once the layout design, location and materials have been determined, it’s time to choose the right cable management system for the job. Make sure you find a system that offers a full range of accessories to ensure a smooth installation. Eaton’s B-Line Series offers one of the widest ranges of cable management solutions in a variety of styles, materials and finishes. Their support recommendations with straight sections, cable tray fittings, vertical adjustable splice plates, heavy-duty expansion splice plates and cable ladder solutions can help eliminate substantial costs in both labor and support materials on any given project.
ALL ABOUT THE SAVINGS
The cable ladder systems were engineered to reduce the number of structural supports needed in cable ladder installation, resulting in a lower installation cost through structural steel savings, according to a B-Line Series white paper on structural steel savings.
B-Line Series cable management products are designed to work together for faster installation. For example, the KwikSplice cable channel has a dovetail side rail and guided splice plate system for a fast and easy install. Fittings are shipped pre-assembled with an integrated splice attachment that helps reduce the total installation time. The KwikSplice cable channel can also be cut and spliced at any point along the tray, reducing jobsite complexities by simplifying field modification. Quick connect fittings and accessories provide additional versatility and time savings.
When the right considerations for cable management design, location, material and product are implemented, the result includes a reliable system built with savings on installation time, labor and material.
