1000mm Wide Perforated GI Cable Tray Pre Galvanized Steel for Heavy Cable Loads

Gi Perforated Cable Tray 1000mm

BENDIN Gi Perforated Cable Tray 1000mm is a wide galvanized ventilated tray for high cable fill capacity. Its 1000mm channel carries large bundles of power and control cables, while the pre-galvanized zinc coating protects against humidity in industrial and commercial installations.

Application and Functions in Different Scenarios

Core Functions

1. Efficient Heat Dissipation: the perforated base releases heat generated by loaded power, control and instrument cables, preventing overheating and extending cable service life.
2. Corrosion Protection: pre-galvanized and hot dip galvanized steel resists humidity, salt spray and industrial fumes so the tray stays reliable in demanding environments.
3. Organized Cable Routing: the channel separates power cables from signal cables, reducing electromagnetic interference to sensitive control instruments.
4. Fast Installation and Maintenance: the open perforated design allows quick cable laying, inspection, drop-out and later system expansion without complex civil work.
5. Mechanical Strength and Safety: reinforced side rails support heavy cable loads and provide continuous metal bonding for earthing.

Typical Application Scenarios

Large industrial plants and warehouses.
Power distribution and substations.
Data centers and telecommunication hubs.
Infrastructure and utility corridors.
Heavy manufacturing facilities.

BENDIN Installation & Selection Considerations

1. Material and Surface Selection: evaluate the corrosive media on site and confirm pre-galvanized and hot dip galvanized steel with the correct surface treatment before ordering.
2. Avoid Galvanic Corrosion: never let dissimilar metals touch directly; use matching bolts and insulating gaskets between the tray and carbon steel brackets.
3. Load Calculation and Support Span: calculate the total cable weight to select the correct plate thickness and load class, and reduce the support span where heavy cables concentrate.
4. Thermal Expansion Control: install expansion joints on long straight runs to absorb thermal deformation caused by temperature changes.
5. Continuous Earthing and Bonding: keep continuous electrical bonding across all metal sections, mandatory in hazardous classified zones.
6. Separation of Power and Instrument Cables: use dividers to separate power cables from instrument cables and cut electromagnetic interference.
7. Cutting and Re-Protection on Site: cut with the correct tools and re-protect every cut edge and weld so the corrosion-resistant surface is restored.
8. Surface Inspection Before Installation: check the coating before installation, protect the surface during transport and repair any scratches that expose bare metal.
