Which category does ordinary cable tray belong to

Ordinary cable tray typically belongs to the ladder-type category.OverviewAn ordinary cable tray is generally classified as a ladder cable tray, which consists of two longitudinal side rails connected by evenly spaced rungs, resembling a ladder . This open design provides excellent ventilation, allowing heat generated by power cables to dissipate efficiently, and offers high structural strength to support heavy-duty cables over long spans . Ladder trays are widely used in industrial and utility-scale installations due to their durability and ease of cable management.CharacteristicsOpen Structure: The ladder design allows easy access for cable installation, maintenance, and future expansion .Ventilation: The open rungs prevent overheating of power cables, which is critical for high-current applications .Load Capacity: Suitable for heavy cables and long-distance runs, providing robust support .Material Options: Commonly made from galvanized steel, aluminum, or stainless steel, depending on environmental conditions .ApplicationsLadder-type cable trays are ideal for:Industrial plants and factoriesPower distribution systemsAreas requiring maximum airflow and heat dissipationInstallations where frequent cable access or modifications are expected Comparison with Other TypesPerforated (ventilated) trays: Have a solid bottom with holes for moderate ventilation, suitable for commercial wiring .Solid-bottom trays: Fully enclosed, protecting sensitive control or communication cables .Wire mesh (basket) trays: Lightweight and flexible, often used for data or low-voltage cables .Channel trays: Simple U-shaped design, typically for light-duty applications . In summary, ordinary cable tray is most commonly a ladder-type tray, chosen for its strength, ventilation, and suitability for heavy-duty power cable installations.
