Lithuanian Tray Cable Tray Models and Dimensions

Lithuanian cable trays are available in various types and sizes, including ladder, perforated, wire mesh, and channel trays, with standard widths from 50mm to 600mm, heights from 50mm to 120mm, and lengths typically around 3000mm, manufactured to meet both local and international standards.

Types of Cable Trays

1. Ladder Cable Trays: Designed for heavy cable loads and long spans, ladder trays have open rungs for ventilation and heat dissipation. They are ideal for power and solar DC runs, with side rail heights and material thickness critical for load capacity .
2. Perforated (Trough) Trays: Provide continuous bottom support with ventilation holes, balancing containment and airflow. Suitable for medium loads and environments requiring moderate heat dissipation .
3. Wire Mesh (Basket) Trays: Lightweight, flexible, and easy to install, these trays are ideal for low-voltage, telecommunication, and fiber optic cables. They allow excellent air circulation and quick cable access .
4. Channel Trays: Compact U-shaped trays for light-duty applications, often used in confined spaces or short cable runs .

Standard Dimensions

• Widths: Commonly 50mm, 100mm, 150mm, 200mm, 300mm, 400mm, 500mm, 600mm .
• Heights (Side Rail): Typically 50mm, 70mm, 100mm, 120mm .
• Lengths: Standard straight sections are usually 3000mm, facilitating transport and installation .
• Material Thickness: Varies by tray type and load requirements; thicker materials increase load capacity and reduce deflection .
• Rung Spacing (Ladder Trays): Adjustable depending on cable weight and heat dissipation needs .

Materials and Coatings

Cable trays in Lithuania are manufactured from steel, stainless steel, aluminum, or galvanized steel, with options for hot-dip galvanization, powder coating, or bare metal to suit environmental conditions . Wire mesh trays are typically welded steel wires for durability and flexibility .

Customization and Compliance

Lithuanian manufacturers, such as Jeetmull Jaichandlall, offer custom-made trays tailored to specific project requirements, including size, shape, color, and load capacity . All trays adhere to industry standards for structural integrity, cable fill, and ventilation, ensuring compliance with both local and international electrical codes .

Practical Considerations

• Cable Fill: Tray sizing should be based on the total cable area, not just conductor size, to prevent overcrowding and heat buildup .
• Installation: Trays can be wall-mounted, ceiling-suspended, or underfloor, depending on project needs .
• Load and Span: Ladder trays are preferred for heavy loads, while wire mesh and channel trays are suitable for lighter applications . Lithuanian cable trays provide a versatile and code-compliant solution for industrial, commercial, and telecommunication installations, with a wide range of standard and custom dimensions to meet diverse project requirements.
