Efficient Cable Protection
Physical Protection: Metal or non-metal enclosures prevent mechanical damage, rodent/insect attacks, and foreign object intrusion. Fire-resistant trays use flame-retardant materials, meeting 1–3 hour fire ratings per building codes (e.g., GB50016).
Environmental Adaptability: Anti-corrosion treatments (hot-dip galvanizing, powder coating, zinc-nickel plating) suit humid, salty, or chemical environments. Explosion-proof designs meet safety needs in flammable settings (e.g., gas stations, chemical plants).
Optimized Cable Management
Orderly Routing: Internal partitions separate power, control, and communication cables, reducing electromagnetic interference. Multi-layer setups maximize vertical space, ideal for dense installations.
Flexible Expansion: Modular design allows on-site cutting and assembly, adapting to complex layouts. Reserved space simplifies future cable additions without rework.
Efficient Heat Dissipation & Easy Maintenance
Heat Dissipation: Mesh trays offer 65–80% ventilation, speeding heat release and reducing insulation aging. Perforated trays and optional forced ventilation further improve cooling.
Maintenance Ease: Ladder trays’ open design allows easy inspection and fault detection; trough trays with removable covers support live maintenance (with insulation protection).
Cost Efficiency
Lower Initial Costs: Standardized production reduces unit costs (steel trays ~RMB 20–200/m; fiberglass slightly higher but longer-lasting). Compared to buried or conduit systems, trays are more cost-effective over long runs.
Low Life-Cycle Costs: Galvanized steel trays last 20–30 years, aluminum 15–25 years, with minimal maintenance (5–10% of initial cost).
Efficient Installation & Safety
Fast Installation: Prefabricated, bolted components eliminate welding, cutting installation time by 60% vs. trenches. Lightweight designs (aluminum ~⅓ steel weight) ease overhead work.
Reliable Grounding: Systems connect via grounding wires (e.g., 4mm² copper braid) to building ground, ensuring ≤4Ω resistance for lightning and leakage protection.
