Construction of large-span cable trays in Vietnam

Large-span cable trays in Vietnam are designed for heavy-duty industrial applications, offering high load capacity, corrosion resistance, and adaptability to hot and humid conditions.

Overview of Large-

Span Cable TraysLarge-span cable trays differ from standard trays by providing extended support spans and high loading capacities, making them suitable for heavy cables such as power, communication, thermocouple, and control system cables. They are commonly used in industrial factories, power plants, oil and gas facilities, and data centers across Vietnam. These trays are engineered to withstand harsh environmental conditions, including high humidity and heat typical of Vietnam's climate.

Materials and FinishesLarge-span cable trays are manufactured from stainless steel (304/316), fiberglass reinforced plastic (FRP), and aluminum alloy. Finishes include pre-galvanized, hot-dipped galvanized, and powder-coated surfaces, providing excellent corrosion resistance, heat resistance, and long service life. Hot-dip galvanized (HDG) trays are particularly effective in humid industrial environments, as demonstrated in projects like the Vietnam Nghigon Factory.

Types and StructuresLarge-span cable trays come in various shapes and styles: Ladder type: Open design for ventilation and heat dissipation. Channel type: Solid or perforated for heavy-duty support. Perforated type: Allows airflow and reduces weight.

They can be configured into straight runs, horizontal bends, tees, crosses, reducers, and vertical bends, enabling flexible routing in complex industrial layouts.

Installation Considerations

Installation of large-span cable trays involves: Support accessories: Corbels, hangers, brackets, and strut channels to ensure stability and load distribution. Load management: Proper spacing and support to handle heavy cables without sagging. Environmental adaptation: Selection of materials and coatings to resist corrosion, UV exposure, and heat in outdoor or humid indoor conditions.

Maintenance: Easy access for inspection and cable replacement, with long-term durability reducing maintenance frequency.

Suppliers in Vietnam

Vietnam has several suppliers and manufacturers of cable trays, including Dong Kwang Vina, which offers a wide range of cable support systems such as ladder trays, solid bottom trays, perforated trays, and accessories. Other suppliers provide carbon steel and stainless steel options suitable for industrial projects.

Summary

For industrial projects in Vietnam, large-span cable trays provide a reliable solution for heavy-duty cable management, combining high load capacity, corrosion resistance, and adaptability to hot and humid conditions. Proper selection of material, finish, tray type, and installation accessories ensures safe, efficient, and long-lasting cable infrastructure.
