Preliminary Site Survey
We conduct on-site dimension measurement. Based on cable quantity and category, we determine cable tray specifications and design optimal routing plans. We arrange layered layout for high-voltage power cables, low-voltage cables, control cables and computer shielded cables to prevent electromagnetic interference.
-
Cable Tray Assembly
We assemble ladder trays, trough-type shielded trays together with full sets of fittings including cross joints, tees and vertical elbows. Only original factory parts such as connecting plates, angle adjusters, brackets and I-steel uprights are adopted.
-
Fixation & Installation
We install wall-mounted, hoisted and ground-mounted supports. Support span and overall load capacity are strictly calculated. Outdoor cable trays are equipped with rain shields, and all welding joints receive anti-corrosion treatment.
-
Earthing Construction
Flexible copper jumpers are used for tray connections. Long-distance cable trays adopt sectional repeated earthing to ensure electrical safety in line with relevant standards.
-
Cable Separation
Partition plates are installed when strong current and weak current cables share one tray. The cable filling ratio is strictly controlled below 40% to reserve space for future expansion.
