Introduction
The Cablofil cable tray system is designed for use in a wide range of commercial and industrial applications, offering a combination of performance, safety, and cost-effectiveness. This article provides a detailed overview of the Cablofil cable tray, focusing on installation considerations, technical specifications, and frequently asked questions based on official documentation and product resources. The system is engineered to support complex configurations, ensuring adaptability and ease of installation in environments where cable management is critical.
The data presented here is derived from official technical documentation, product specifications, and user inquiries sourced from the Legrand website and associated support resources. These materials provide essential insights into the structural design, material composition, and application suitability of the Cablofil system. The information is particularly relevant for U.S.-based professionals, including electricians, engineers, and IT technicians, who are responsible for implementing and maintaining cable tray systems in industrial and commercial settings.
Key Features and Design Characteristics
The Cablofil cable tray system is characterized by several design elements that enhance its functionality and usability in complex environments. One of the most notable features is the Special Safe-T-Edge, which protects installers from sharp edges and prevents cable fraying. This feature is particularly important in environments where worker safety and cable integrity are priorities.
Another key attribute is the wire mesh design, which is smooth and round to resist the accumulation of dirt and dust. This design is beneficial in clean environments such as manufacturing plants or laboratories where contamination control is necessary.
The standard 10-foot lengths of the cable tray allow for straightforward handling and installation, reducing the need for on-site cutting and assembly. The large mesh size—2 inches wide by 4 inches long—enables easy routing of cables without the need to cut or modify the tray. This feature enhances flexibility during installation and allows for efficient cable access.
The Cablofil system is also known for its lightweight yet durable construction, which ensures maximum strength with minimal weight. This characteristic makes it ideal for applications where structural load capacity is a concern, such as in suspended ceilings or overhead installations.
Installation Considerations
Proper installation of the Cablofil cable tray system is essential to ensure both performance and safety. While the product documentation does not provide a complete, step-by-step installation manual in the provided source material, several key considerations and best practices are highlighted through user inquiries and supporting technical resources.
Compatibility and Accessories
The Cablofil system is designed to be adaptable to a wide range of configurations, supported by a comprehensive range of universal and unique accessories. These include fittings, connectors, and expansion kits that allow for seamless integration into existing infrastructure. For example, the Expansion Splice Kits (EZ-2) are recommended for use in spans where thermal expansion and contraction may affect the integrity of the system.
Users are encouraged to consult the Cutsheet and Installation Instructions provided by the manufacturer for detailed guidance on accessory compatibility and installation requirements. These documents typically outline the necessary hardware, fasteners, and mounting methods for different types of installations.
Fastening Recommendations
A common question among installers concerns the appropriate type of fasteners to use in specific environments. One of the frequently asked questions from the source material relates to the use of stainless steel bolts and screws when installing the cable tray within a PLC (Programmable Logic Controller) panel. The recommendation to use stainless steel fasteners suggests that corrosion resistance and durability are important factors in such applications.
However, the source material does not provide a definitive answer or official recommendation from the manufacturer. Therefore, users are advised to refer to the Installation Instructions or contact technical support for confirmation on the appropriate fastening materials for their specific project.
Cleanroom and Environmental Considerations
The Cablofil system is also being used in clean environments, such as ISO 07 cleanrooms, where contamination control is a critical factor. One of the questions posed in the source material asks whether the electroplated zinc-finished cable tray, such as the CF105 4" High Side Rail, is suitable for use in such environments.
While the source material does not provide a direct answer from the manufacturer, the smooth and round wire mesh design of the Cablofil system appears to be well-suited for cleanroom conditions. This is because the design minimizes the accumulation of dust and dirt, which is essential in maintaining the required environmental standards.
Voltage and Load Capacity
Another frequently asked question concerns the voltage rating of the Cablofil system when using 3C/2 TC-ER cable. The question specifically asks whether the model can be rated for 480V.
The source material does not include an official response to this inquiry, but users are directed to consult the Installation Guide and technical bulletins for detailed information on voltage compatibility and electrical ratings. It is also recommended to verify the cable tray’s load capacity and ensure that it meets the requirements of the specific electrical installation.
Expansion and Support Requirements
The source material includes a question regarding the intervals at which Expansion Splice Kits (EZ-2) should be installed. The user notes that this information is not included in the Installation Guide, which is a common concern among installers who rely on manufacturer documentation for precise guidance.
While the source material does not provide a definitive answer, the general principle for expansion joints in cable tray systems is to accommodate thermal expansion and contraction caused by temperature fluctuations. The intervals at which these joints should be installed depend on the length of the run, the ambient temperature range, and the material properties of the cable tray.
Installers are advised to follow industry standards, such as those outlined in NEC (National Electrical Code) or UL (Underwriters Laboratories) guidelines, when determining the placement of expansion joints. In the absence of specific manufacturer recommendations, consulting a qualified electrical engineer or technical support representative is recommended to ensure compliance and optimal performance.
