The Cable Tray connection and fixing system has a complete category classification, which can be divided into multiple specialized types according to different installation structures, docking methods, and fastening forms. Different types of connections and fixing methods are adapted to different bridge structures and installation environments, with clear division of labor and strong targeting. They are the foundation for building a stable, standardized, and standardized bridge wiring system, which can comprehensively cover the wiring and fixing needs of various conventional and complex electromechanical installation projects.

Classified by bridge docking connection form, covering the entire range of splicing types. It mainly includes five core types: straight plate docking connection, corner bending connection, three-way branch connection, variable diameter transition connection, and high-low drop connection. Straight board docking is suitable for horizontal straight line extension splicing of bridge frames; Corner connections are specifically designed to accommodate 90 degree and 45 degree turning wiring; Three way connection meets the requirements of line diversion and merging wiring; Variable diameter connection can achieve smooth transition between wide and narrow bridge frames; The bridge connection of high and low drop connections is suitable for floor and ceiling height differences, covering various bridge splicing conditions in all aspects.

Classified by on-site fastening and fixing methods, suitable for various installation needs. It is divided into four mainstream types: lifting fixed, side wall fixed, floor standing fixed, and sandwich hanging fixed. Lifting and fixing rely on suspension rods and frames for matching and fastening, and are commonly used for hanging wiring in indoor ceilings; Fixed side wall with support arm and expansion bolt installation, suitable for wall and beam column side wiring; Fixed on the ground and reinforced with anchor fasteners, suitable for laying low level cable trays on the ground; The sandwich hanging fixation is a compact fixing method, specifically used for installation in confined spaces such as narrow pipe wells and equipment gaps.

Classify according to the material of the fastening structure and adapt to different working conditions and environments. It includes four commonly used types: galvanized steel connection fixing, spray anti-corrosion fastening, hot-dip galvanized high-strength fixing, and stainless steel anti rust connection. The conventional steel version has high cost-effectiveness and is suitable for indoor dry environments; Spray painted style with uniform color, scratch resistant and wear-resistant, suitable for high-end decoration projects; Hot dip zinc resistant to corrosion and weathering, suitable for outdoor outdoor scenes; Stainless steel is rust resistant, acid and alkali resistant, specially designed for harsh corrosion conditions such as coastal and chemical industries. The variety is complete and can be selected according to needs.

Classified by load-bearing reinforcement type, suitable for light and heavy load engineering. It is divided into ordinary standard type connection fixation, thickened and reinforced type fixation, and heavy-duty reinforced type connection fixation. Standard type is suitable for light and ordinary cable wiring; Thickened and reinforced type improves stability by thickening the plate and encrypting the firmware, suitable for medium load scenarios; The heavy-duty reinforcement type, combined with specialized reinforcement connectors and multi-point fixed structures, can withstand large-span and heavy cable loads, and is suitable for industrial heavy-duty and high-altitude long-distance laying projects.
