How to Choose Photovoltaic Cable Trays in Mongolia

Photovoltaic cable trays in Mongolia should be installed using durable, climate-resistant materials with proper structural support to withstand extreme temperatures and high winds.

Material Selection and Environmental Considerations

For solar projects in Mongolia, hot-dip galvanized steel, stainless steel, or aluminum cable trays are recommended due to their resistance to corrosion and harsh weather conditions . Hot-dip galvanized trays are particularly effective in protecting against moisture and temperature fluctuations, which are common in Mongolian climates . Reinforced perforated or ladder-type trays improve structural stability and allow for proper ventilation and heat dissipation .

Installation Procedures

1. Inspection and Preparation: Upon delivery, all trays and accessories should be inspected for damage, deburred, and cleaned to remove any galvanization residues or zinc dross .
2. Support and Mounting: Cable trays should be self-supporting and fixed to steel structures, concrete, or pipe racks using standard steel shapes or self-drilling dowels. Maximum support spacing is typically 3 meters for ladder trays and 2 meters for perforated trays to prevent sagging .
3. Orientation: Trays should be installed flat wherever possible, under flooring or walkways. Vertical or edgewise installation is only used when necessary, with cables secured using stainless steel strips or fasteners .
4. Load Capacity: Design trays to carry the expected cable load, often around 100 kg/m, ensuring they can support heavy-duty photovoltaic cables without deformation .
5. Covers and Protection: Use covers in areas with high risk of mechanical damage. Covers should match the tray material and be securely fastened with manufacturer-recommended clips .

Compliance and Standards

Installation should follow NEMA VE1, NEMA VE2, IEC, and local electrical codes to ensure safety, reliability, and interoperability with other electrical components . Proper adherence to these standards ensures long-term operational stability and reduces maintenance requirements.

Practical Tips

• Collaborate with EPC contractors to ensure tray layout meets both technical and environmental requirements .
• Use reinforced C-channel systems or trunking for additional structural support in high-wind areas .
• Plan cable routing to minimize exposure to environmental elements and facilitate maintenance .
• Conduct post-installation inspections to verify alignment, load distribution, and secure fastening . By following these guidelines, photovoltaic cable trays in Mongolia can achieve durable, efficient, and safe cable management, ensuring reliable operation of solar power installations even under extreme environmental conditions .
