Cable trays are also called wire troughs

Cable trays are sometimes referred to as wire troughs, particularly when describing ventilated or channel-style trays. Cable trays are structural systems used to support and organize electrical cables in commercial and industrial installations, offering an alternative to conduit systems and open wiring. Among the various types, a trough cable tray—also called a ventilated trough—features a bottom with slots or holes, providing both support and airflow for cables.

This design allows heat dissipation while maintaining cable organization, making it suitable for mixed power and control cables. Terminology: Wire troughs or cable troughs generally refer to cable trays with a deep, solid, or ventilated bottom that forms a channel-like enclosure for cables. Solid-bottom trays provide maximum protection but limited ventilation, while ventilated troughs balance support and airflow.

Other types include ladder trays, wire mesh trays, and channel trays, each optimized for specific cable loads, heat management, and installation environments. Key Points: Wire troughs are essentially a subtype of cable trays, emphasizing a channel or trough shape. They are commonly used in industrial and commercial facilities where moderate protection and ventilation are needed.

The term “wire trough” is less formal but widely understood in engineering and construction contexts to describe these tray types. In summary, while not all cable trays are called wire troughs, ventilated or channel-style cable trays are often referred to as wire troughs, highlighting their trough-like structure and cable-support function.
