Laying of Mongolian Trough-type Cable Trays

Mongolian trough cable trays are robust, floor-laid or embedded systems designed to securely route electrical cables, pipes, and utilities using solid or ventilated troughs with removable covers.

Overview of Cable Trough Systems

Cable troughs are specialized cable management systems that provide safe, secure, and practical routing for electrical and communication cables, often used in industrial, commercial, and transportation facilities. They can be permanent or temporary, allowing flexibility for cable installation, maintenance, and future modifications. These systems are particularly suitable for environments where cables need protection from mechanical damage, dust, or moisture.

Materials and Construction

Mongolian trough cable trays are typically constructed from: Fibre-reinforced concrete: Provides high lateral stability and durability for heavy-duty applications. Recycled composite materials (polypropylene): Lightweight, corrosion-resistant, and suitable for various load requirements. Ductile iron covers: Solid, non-slip, and often KTL-coated for durability, with pre-fitted removable steel caps for flexible cable entry points.

The troughs are designed with extra-thick channel bases and side walls to withstand mechanical loads and environmental stress. Covers are often boltless and lockable, allowing quick removal and reinstallation during cable laying or maintenance.

Installation Guidelines

Site Preparation: Ensure the installation area is level and free of debris. For floor-laid troughs, a flat surface with proper support is essential. Material Inspection: Verify that all trough sections, covers, and accessories meet project specifications and are free from damage.

Layout and Alignment: Follow approved shop drawings for trough routing, including bends, junctions, and cable entry points. Support and Spacing: Troughs should be supported at regular intervals to prevent sagging. For industrial applications, spacing depends on load and trough material.

Cable Installation: Place cables carefully to avoid exceeding bend radius limits. Use cable ties or separators as needed to maintain organization and airflow. Cover Installation: Apply foot pressure to engage boltless locking systems, ensuring covers are securely in place.

Standards and Compliance

Mongolian trough cable trays should comply with IEC 61537 for cable tray systems, which specifies requirements for construction, testing, and performance. Additional guidance can be obtained from the Cable Tray Institute (CTI) and manufacturer-specific installation manuals. These standards ensure: Structural integrity under loadProper cable spacing and bend radiusResistance to environmental factors such as moisture, dust, and corrosionApplicationsThese cable trough systems are widely used in: Industrial plants and warehousesAirports and railway terminalsSports stadiums and exhibition hallsData centers and control roomsThey are particularly advantageous in dust-prone or high-traffic areas, as the solid covers minimize accumulation and protect cables from mechanical damage.

Maintenance Considerations

Regular inspection of covers and trough sections for damage or corrosionCleaning of debris from troughs to maintain airflow and prevent moisture buildupEnsuring cable organization and separation are maintained for safety and performanceBy following these construction and installation practices, Mongolian trough cable trays provide a durable, flexible, and safe solution for managing electrical and communication cables in demanding environments.
