The standardized connection and fixed dimensions of Cable Trays are the core foundation for ensuring seamless integration, stable installation, and orderly wiring of the entire tray system. All conventional trays and supporting connectors adopt industry standard standardized size parameters, which are compatible with domestic mechanical and electrical installation specifications and mainstream construction standards. Unified connection hole spacing, overlap length, and fixed point size can achieve smooth docking and regular horizontal and vertical fixation of bridge frames, eliminating installation looseness, docking gaps, and uneven stress caused by size deviations, and adapting to various standardized engineering batch construction.

The standard connection dimensions of the bridge frame are standardized and have high docking accuracy. Conventional cable trays adopt standardized lap sizes, with standard lap allowances reserved at the beginning and end of single section trays, suitable for straight extension docking of trays of the same specifications. The supporting connecting pieces, connecting plate aperture, and hole spacing are all fixed standard sizes, perfectly matching the corresponding width and height of groove, ladder, and Tray type cable trays, without the need for on-site drilling, hole modification, or cutting. The connecting pieces are precisely fitted to the cable tray body, and the docking gaps are uniform and tight, ensuring the continuity and integrity of the entire line laying.

Standardize fixed installation dimensions and adapt to universal support accessories. The lateral fixation, lifting fixation, and wall support arm installation of the bridge frame all follow the fixed size standards. The installation hole spacing, edge distance, and fixing point positions are unified and compliant, and can be directly adapted to commonly used market brackets, support arms, suspension rods, expansion bolts, and other fixing accessories. Standardized dimensions are compatible with various conventional installation processes, whether it is ceiling hoisting, wall side installation, or ground overhead fixation, they can be accurately aligned and installed, avoiding construction hazards such as mismatched accessories, installation deviation, and unstable fixation caused by non-standard dimensions.

Strong size adaptability and compatibility with the entire project construction. Standardized connections and fixed dimensions are suitable for general scenarios such as indoor and outdoor conventional engineering, municipal infrastructure, factory wiring, commercial buildings, etc. Bridge trays of the same specifications can be arbitrarily spliced and extended, corner docking, and layered fixation. The entire project has uniform dimensions and consistent patterns. Fixed parameters effectively ensure the flatness and verticality of bridge installation, even distribution of stress points, eliminate local suspension, looseness, and deformation problems, greatly improve the overall stability and engineering acceptance rate of the bridge, and adapt to batch standardized construction landing.
