Mesh cable trays and cable tray connections

Mesh cable trays are a specialized type of cable tray that provide flexible, ventilated support for cables, and they connect to standard cable tray systems using compatible fittings, couplers, or splice kits.

Overview of Cable Trays

A cable tray system is a structured framework designed to support and organize electrical, control, and communication cables. It consists of straight sections, bends, tees, risers, reducers, covers, and support elements such as wall brackets or trapeze hangers, forming a rigid and accessible pathway for cables. Standard cable trays can be made of solid, ventilated, or ladder-style designs, providing mechanical support and protection while allowing easy maintenance and upgrades.

Mesh Cable Trays

Mesh cable trays, also known as wire mesh trays, are constructed from a grid of metal wires, offering high ventilation, flexibility, and ease of installation. They are particularly suitable for power, control, and data cables in environments where frequent changes or branching of cables are required. Mesh trays allow cables to be fed in multiple directions, and their bendable structure enables simple creation of turns, branches, and exits.

They are available in different types depending on load requirements and cable quantity.

Connection Methods

Connecting mesh cable trays to each other or to standard cable trays requires specialized accessories to ensure structural integrity and alignment: Couplers and splice plates: Used to join straight sections of trays securely, maintaining load-bearing capacity. Bolts or clip systems: Provide rigid connections for heavier cable loads or industrial applications. Proprietary connector kits: Offered by manufacturers for tool-less or fast installation, ensuring compliance with load ratings and standards.

Compatibility considerations: It is recommended to use trays and connectors from the same manufacturer to avoid misalignment or uneven load distribution. Integration with Standard Cable TraysMesh trays can be integrated into a larger cable tray system by using fittings such as horizontal or vertical bends, tees, and reducers, similar to standard trays. Support elements like wall brackets, suspended supports, or center suspensions are used to attach both mesh and standard trays to the building structure.

This allows a continuous, organized, and safe cable routing system that combines the flexibility of mesh trays with the structural strength of standard trays.

Key Advantages

Flexibility: Mesh trays allow easy modifications and branching of cables. Ventilation: Open grid design reduces heat buildup. Compatibility: Can be connected to standard cable trays using appropriate fittings and connectors.

Efficiency: Reduces installation time while maintaining compliance with electrical standards. In summary, mesh cable trays are a versatile subset of cable tray systems that can be seamlessly connected to standard trays using couplers, bolts, or manufacturer-specific kits, providing both flexibility and structural support for complex cabling installations.
