Detailed explanation of tray type bridge products
Perforated Cable Tray is a cable support system with bottom punched holes and side enclosed, which combines heat dissipation, load-bearing capacity, and moderate protection. It is widely used in industrial plants, power systems, data centers, and other scenarios. Its design balances the advantages of open ladder and closed trough, and is one of the mainstream choices for cable laying.
1. Product structure and materials
(1) Core components
Tray body: cold-rolled steel plate (galvanized/spray coated) | Functional features: bottom punching (heat dissipation), side closure (anti dust falling)
Connection: Galvanized bolt+grounding plate | Functional features: Ensure mechanical strength and electrical connectivity
Attachment: Bent joint, tee joint, variable diameter joint | Functional features: Suitable for complex wiring paths
(2) Material classification
Galvanized tray: hot-dip galvanized (zinc coating ≥ 65 μ m), corrosion-resistant
Stainless steel tray: 04/316L stainless steel, acid and alkali resistant
Aluminum alloy tray: lightweight (density only 1/3 of steel), non-magnetic
2. Main application scenarios
(1) Industrial sector
-Power system: Cable laying in substations (with strong load-bearing capacity and good heat dissipation).
-Automotive manufacturing: power cable support for production lines (resistant to oil and impact).
(2) Data Center and Communication
-Server room: high-density cable management (requires cable combing and organization).
-5G base station: outdoor antenna feeder laying (IP54 protection).
(3) Special environment
-Food factory: Stainless steel trays are easy to clean (compliant with HACCP standards).
-Cleanroom: Aluminum alloy tray anti-static (ISO Class 8).
Tray type cable tray is a cost-effective choice for industrial and data center scenarios, with its core advantages being:
1. Balance between heat dissipation and load-bearing capacity (better than the heat dissipation of trough type cable trays and stronger than the protection of ladder frames);
2. Flexible expansion (can easily add or remove cables, easy maintenance);
Selection mnemonic:
-Heavy duty selection of steel (hot-dip galvanized/stainless steel), lightweight selection of aluminum type;
-Heat dissipation should be viewed through openings (≥ 30%), and anti-corrosion should be viewed through the environment.
