FAQs about New Style Cable Tray
The three main types of cable trays are Ladder Cable Tray, Ventilated Trough Cable Tray, and Solid Bottom Cable Tray.
Ladder Cable Tray: The most commonly used type, accounting for about 75% of installations. This tray consists of two side rails connected by rungs, allowing for excellent airflow and heat dissipation, which is particularly important for high-voltage cables. It is ideal for managing a large volume of cables and is widely used in industrial and commercial settings. The open design provides easy access for installing, maintaining, and securing cables.
Ventilated Trough Cable Tray: This tray has a more solid design than the ladder type but includes ventilation holes for airflow. It is often selected for aesthetic reasons, as the cables do not droop in visible areas. The ventilated trough tray offers more support for cables compared to ladder trays, though it is not as suitable for cables that need maximum airflow.
Solid Bottom Cable Tray: Typically used for cables that require additional protection from electromagnetic interference (EMI) or radio frequency interference (RFI). The solid base prevents moisture accumulation and offers shielding for sensitive electrical systems, making it ideal for locations that demand superior protection.
Each tray type serves different needs depending on the specific installation environment, the type of cables being managed, and the overall design requirements.
While cable trays are an excellent solution for routing power and control cables, there are certain types of cables that are not permitted for installation on them, according to various electrical codes like the National Electrical Code (NEC).
Non-Plenum Cables: Cables that are not rated for plenum spaces are generally not suitable for installation in cable trays, especially in commercial or industrial buildings. Plenum-rated cables are designed to be fire-resistant and to emit low smoke in case of a fire, which is crucial in areas where airflow is a concern, such as air ducts or other enclosed spaces.
Cables Without an Insulated Jacket: Cables that lack an outer insulated jacket or protective covering (such as some unjacketed power cables) should not be installed in cable trays, as the cables need to be adequately protected from physical damage and environmental hazards.
Cables with Limited Fire Resistance: Cables that are not rated for fire resistance or do not meet specific fire ratings (like CMR, CMP, or NPLF) are not allowed in cable trays, particularly in areas that require fire safety compliance. This includes cables that could pose a higher risk of fire spreading in the event of a malfunction or heat buildup.
Communication and Low-Voltage Cables: In some cases, low-voltage or communication cables (such as telephone or data cables) may not be suitable for tray installations due to different codes or standards. These cables often require separate, dedicated pathways to ensure signal integrity and safety.
To ensure safety and compliance, always check the manufacturer’s recommendations and relevant local electrical codes before installing any cable in a tray.
The life expectancy of a cable tray largely depends on the material used, environmental conditions, and the level of maintenance it receives over time.
Material: The most common materials used for cable trays include galvanized steel, stainless steel, and aluminum. Galvanized steel cable trays typically last between 20 to 50 years, depending on the environment in which they are installed. If installed in corrosive environments (such as coastal areas), they may have a shorter lifespan unless they are treated or coated with special corrosion-resistant materials.
Environmental Factors: Environmental conditions can significantly impact the life expectancy of a cable tray. For instance, trays exposed to extreme heat, moisture, corrosive chemicals, or salt air will degrade more quickly than those in dry, clean environments. Stainless steel trays, particularly in marine or industrial environments, are known for their durability and can last up to 50 years or more if properly maintained.
Maintenance: Regular inspection and maintenance are essential for maximizing the lifespan of cable trays. Checking for wear, corrosion, and ensuring that the tray is free of debris and obstruction will help extend its operational life. Well-maintained trays tend to last longer, whereas neglecting upkeep may shorten their lifespan.
Ultimately, a properly installed and maintained cable tray system, made from high-quality materials and located in favorable conditions, can last for decades.
When comparing cable tray systems to conduit installations, cable trays tend to be more cost-effective, especially for larger-scale projects or where flexibility is required. Several factors influence the cost comparison:
Material and Installation Costs: Cable trays are generally less expensive to install than conduit systems because they do not require the same level of labor-intensive work. Tray systems are often modular and can be installed more quickly, reducing labor costs. In contrast, conduit systems usually require more precise measurements, fittings, and additional labor to bend and install, driving up installation costs.
Maintenance: Over time, cable trays are easier and cheaper to maintain than conduit systems. Conduit systems are sealed and require more effort to inspect and maintain cables, especially if damage occurs. With cable trays, it is easier to access and replace cables, and since the system is open, regular inspections are simpler and less expensive.
Flexibility: One of the biggest advantages of cable trays is their flexibility. Cable trays can accommodate changes and additions more easily than conduits, which often require significant modifications. This flexibility allows for easier upgrades or additions to the electrical system without the need for expensive retrofitting.
Long-Term Savings: Though the upfront costs of cable trays may be slightly higher for some configurations, the long-term savings in terms of installation, maintenance, and flexibility make cable trays a more cost-effective solution overall. They also have a higher load-bearing capacity and are more suited for larger installations, which makes them an ideal choice for industrial and commercial buildings where flexible cable management is a priority.
