Solar Farm Cable Tray Project with Hot Dip Galvanized Ventilated Trays

Project Background

A utility-scale solar farm in an arid, high-temperature region needed a cable management system to route DC and AC cabling across a large site. The installation would be fully exposed to intense sun, temperature swings, wind-blown sand and occasional rain, making durability and heat management essential. The EPC contractor selected Langfang Henghao Metal Products Co., Ltd. to supply trays engineered for both the environment and the volume.

Client Requirements

• Long-life corrosion protection for an outdoor desert site
• Ventilated design to keep cable temperatures under control
• Lightweight trays to reduce loading on mounting structures
• Large-volume supply with consistent quality

The Challenge

Solar farms combine long cable runs, high ambient temperatures and full exposure to the elements. Trays must resist corrosion for decades with minimal maintenance, while their open design helps dissipate the heat generated by power cables operating near their capacity. Any premature failure would mean expensive field repairs in a remote location.

Our Solution

We supplied hot-dip galvanized ventilated steel cable trays with high open area for airflow, in a range of widths to suit both string and main DC collection runs. The galvanized finish was specified with a robust zinc coating to withstand the harsh site conditions.

Logistics and Quality

We coordinated large-volume production with phased deliveries to match the construction sequence, and provided coating and material documentation for each batch.

Results and Outcomes

• Thousands of meters of ventilated tray delivered on schedule
• Strong corrosion protection suited to the desert climate
• Airflow design supported cable thermal performance
• Consistent quality across the full supply

The project demonstrated how ventilated galvanized trays combine heat management with the long service life required by outdoor renewable energy installations.

Client Feedback

The EPC contractor noted that the trays installed quickly thanks to the modular accessories and that delivery reliability helped keep the construction programme on track.

Designing for Arid Conditions

High temperatures and wind-blown sand place unusual demands on outdoor cable management. Ventilated trays avoid trapped heat, while a substantial galvanized coating resists both corrosion and abrasion. Spacing the trays generously and using covers only where necessary further improves airflow and extends service life in desert solar installations.
