Vietnamese steel cable trays are available in various types, sizes, and protective finishes, designed to support and organize power and control cables in industrial and commercial settings.

Material and Thickness

Vietnamese steel cable trays are typically fabricated from premium-grade steel to ensure durability and corrosion resistance . The thickness ranges from 1.0 mm to 2.5 mm, with hot-dip galvanized trays requiring a minimum thickness of 1.5 mm for adequate protection . Electro-galvanized and powder-coated options are also available to enhance corrosion resistance .

Dimensions

Standard lengths of cable trays are 2400 mm to 3000 mm, with heights ranging from 50 mm to 200 mm and widths from 100 mm to 900 mm, depending on the type and application . These dimensions allow flexibility for routing multiple cables and accommodating different load requirements.

Types of Cable Trays

  1. Ladder Type: Consists of two longitudinal side rails connected by transverse rungs, providing maximum ventilation for heat-producing cables such as power cables .
  2. Solid Bottom: Made from a single sheet of metal, offering protection from external damage, suitable for control, communication, and non-heat-producing cables .
  3. Perforated Tray: Combines ventilation and protection, often used in environments requiring moderate airflow and cable support .

Protective Coatings

  • Hot-dip galvanizing: Provides long-term corrosion resistance, especially in tropical climates .
  • Electro-galvanized coating: Suitable for indoor or less corrosive environments .
  • Powder coating: Offers additional protection and aesthetic customization .

Accessories and Installation

Cable trays are complemented by a range of accessories for installation and directional changes:

  • Elbows (horizontal and vertical) for directional routing
  • Tees and Crosses for multi-directional connections
  • Reducers to connect trays of different widths
  • Covers (solid or louvered) to protect cables from sunlight, dust, and accidental contact
  • Splice plates, clamps, brackets, and hangers for secure assembly

Applications

Vietnamese steel cable trays are widely used in power plants, oil and gas facilities, data centers, hospitals, and industrial buildings, providing organized cable management, easy maintenance, and enhanced safety .

Compliance and Standards

Most Vietnamese cable trays comply with NEMA VE1-2002 and TCVN 197-2002, ensuring quality, safety, and compatibility with international installation practices . These specifications make Vietnamese steel cable trays versatile, durable, and suitable for a wide range of industrial and commercial applications.
