Cable tray selection should follow the principle of "Cable Type + Protection Requirements + Scene Suitability":
Control cables, communication cables, and low-voltage cables: Prioritize trough-type cable trays to ensure protection and interference prevention;
Power cables, lighting cables, and high-voltage cables: Prioritize tray-type or ladder-type cable trays to balance protection and heat dissipation requirements;
Damp, dusty, and corrosive environments: Choose trough-type cable trays with covers, or cable trays made of corrosion-resistant materials (fiberglass, hot-dip galvanized);
Large diameter, high quantity cables: Choose ladder-type cable trays, utilizing their high fill rate and excellent heat dissipation.
