All connections, fastening bolts and cable clamps are galvanized. Other groove plates and perforated angle iron surface treatments include electrostatic spraying, galvanizing, and painting.   Drill holes with an electric drill (impact drill) according to the specifications of the expansion bolt, and then insert the expansion bolt. Install the workpiece and tighten the nut.

The fire-resistant cable tray trough type has demonstrated its advantages and capabilities in multiple application scenarios due to its fully enclosed structural design. The trough cable tray can provide directional protection and shielding to prevent mechanical and electromagnetic interference from the outside world on the cables. Therefore, it is particularly suitable for laying interference sensitive cables such as computer cables, communication cables, and thermocouple cables.   Fireproof cable tray trough type has anti-corrosion performance and can protect cables from damage in corrosive environments. This characteristic makes it widely used in highly corrosive places such as chemical plants and electroplating plants.   The trough type cable tray structure is stable and can span a long distance. Therefore, it is suitable for large industrial plants, commercial buildings, and other places that require long-span wiring.   The fire-resistant cable tray trough has good flame retardant properties and can protect the operation of cables in the event of a fire. This characteristic makes it widely used in high-rise buildings, tunnels, subways, and other places that require high fire performance.   The fully enclosed structure of the trough cable tray can prevent dust and moisture. Therefore, it is suitable for places that require dust and moisture prevention, such as electronic factories, dust-free workshops, etc.   In summary, the fire-resistant cable tray trough type can demonstrate its advantages and capabilities in multiple application scenarios. It not only provides directional shielding and protection to prevent external interference and damage to the cable, but also has good flame retardant performance and structural strength, which can protect the operation of the cable in case of fire. In addition, its dustproof and moisture-proof properties also make it widely used in specific places. In practical applications, it is necessary to choose the appropriate fire-resistant cable tray type according to specific scenarios and requirements.

Galvanized cable trays need to meet multiple key indicators before operation, including material quality, galvanized layer performance, dimensional accuracy, mechanical properties, and compliance. The main body thickness of hot-dip galvanized bridge is usually 1.5 to 3mm, with a local small galvanized layer thickness of ≥ 65 μ m. When the thickness is greater than 3mm, the local small thickness is 260um, and the average thickness is 265 μ m. Measure with a magnetic thickness gauge and meet the standards. The galvanized layer should be uniform, without defects such as peeling, flaking, bubbles, cracks, or zinc nodules, and the surface should be smooth and flat.   The zinc layer should not peel off or protrude through grid cutting or hammering detection. The material must meet the design requirements and provide a certificate of conformity. Galvanized flat steel and other auxiliary materials must meet the standard, with a length deviation of+30mm. The allowable deviation for the length of the bridge frame is+5mm, with a deviation of+1mm for widths

In the manufacturing process of fully enclosed cable trays, it is important to avoid certain issues to ensure structural reliability, environmental adaptability, and long-term service life.   Improper or insufficient mixing of resin and curing agent in this case can lead to bubbles, reducing strength and stiffness. Vacuum defoaming technology should be used, and the surface quality should be strictly inspected after curing. Uneven distribution or insufficient content of reinforcing fibers can weaken their load-bearing capacity, and special attention should be paid to the corrosion resistance of fibers in humid environments.   Uneven density of aluminum alloy or stainless steel materials can easily cause bending deformation, and it is necessary to control the processing temperature and regularly replace the cutting tools to reduce errors. Untreated cutting burrs may damage the cable and require laser or waterjet cutting followed by polishing. Failure to design reinforcement bars or cross-sectional dimensions based on cable weight and distribution may result in static deformation. Need to optimize the span through CFD simulation.   Non standard components such as elbows and tees are not made with matching finished products, and manual production can easily cause the cover plate to fail to close or make cable laying difficult. Weather resistant resin or coating is not used in high temperature or corrosive environments, which accelerates aging. The bridge structure in the chemical area needs to pass a 48 hour salt test. Excessive bending or small radius of the bridge frame may result in the inability to install the cover plate, and expansion joints need to be reserved according to the specifications. The connecting plate bolts are mistakenly installed on the inner side or without elastic gaskets, which can easily loosen and crack in vibration environments. The fiberglass bridge frame without pre embedded grounding terminals or jumper wires with a cross-sectional area of less than 4mm may cause electric sparks to carbonize the surface. The lack of electrochemical insulation treatment between the metal bridge and steel support resulted in galvanic corrosion.   The joint of the fully enclosed bridge is not sealed with flame-retardant tape, or the fire compartment is not sealed, resulting in the loss of dust and fire prevention function. The lack of UV protection layer will accelerate the aging of resin matrix and shorten its lifespan by more than 30%. Insufficient thickness of the galvanized layer or uneven spraying can cause corrosion in humid environments, and secondary anti-corrosion processes are needed to strengthen it. The manufacturing of fully enclosed cable trays requires strict control over four major aspects: material ratio, structural design, processing accuracy, and protective treatment. Special attention should be paid to the bubble elimination of fiberglass, anti-corrosion connection of metal parts, and environmental adaptability design.

Tray type cable trays have achieved various practical effects in the field of cable laying through their design and material technology. The tray type bridge adopts an open tray structure, with a large width between the bottom and side plates, which can accommodate multiple cables to be laid in parallel. Its load-bearing capacity is significantly higher than that of traditional trough type bridge. Its material can be selected from stainless steel, aluminum alloy, or galvanized steel, which ensures strength and reduces weight, making it suitable for centralized deployment of large capacity cables.   Through plug-in design, fast installation is achieved, and in 2025, its splicing structure is enhanced with positioning plates and bolt limit plates to improve stability and construction efficiency. The open structure facilitates cable layering and avoids clutter, especially suitable for clean wiring of short distance communication lines, while supporting flexible expansion. The bottom and side plates are evenly equipped with heat dissipation holes to dissipate the heat generated during cable operation, avoiding the accumulation of hot air such as the high temperature problem of power cables. The heat dissipation performance is better than that of fully enclosed trough type cable trays. Part of the perforated bridge frames add flexible film at the holes to balance heat dissipation and dust prevention requirements. The semi enclosed structure provides dust and falling object protection. Although it is not as fully enclosed and shielded as the trough bridge, the protection level can be further improved by adding a cover plate.   Suitable for laying high current cables, such as substations and power plants, carrying high power demands. The layout of communication lines in data centers and telecommunications rooms, utilizing their heat dissipation properties to protect data cables. Stainless steel material or hot-dip galvanizing process can be used for cable trays in heavy corrosive environments such as chemical and petroleum industries to extend their service life. By layered installation and reasonable wiring, electromagnetic interference between cables can be reduced, and the reliability of communication lines can be improved. Quick installation modular design supports plug-in splicing, reducing traditional welding steps and lowering construction complexity.   The open structure facilitates cable maintenance and replacement, with high efficiency in troubleshooting, especially suitable for communication lines that require frequent adjustments. Compared to fully enclosed trough type cable trays, tray type cable trays have lower material and construction costs, making them suitable for general-purpose projects with limited budgets. The tray design with simple lines meets the requirements of modern industrial aesthetics and is commonly used in commercial and office buildings.   The tray type bridge achieves a balance between load-bearing, heat dissipation, protection, and construction efficiency through an open structure, perforated heat dissipation technology, and modular design, becoming a universal solution in the fields of power, communication, and industry. The core of its effectiveness lies in its flexible adaptation to different needs. For example, the punched type focuses on heat dissipation, while the non perforated type strengthens protection. Users can choose the configuration according to their specific environment. In the future, with the upgrading of material technology, its performance boundaries will be further expanded.

In the installation process of ladder cable trays, a series of rigorous protective measures must be taken to ensure construction personnel, guarantee project quality, and prevent potential hazards. Before construction, a comprehensive and detailed survey of the project site should be conducted to understand the site environment, wiring requirements, equipment layout, and other conditions. Assess potential risks during the construction process, such as high-altitude operation risks, electrical risks, etc., and develop corresponding risk prevention and control measures. Based on the size specifications and quantity of cable trays, develop a detailed construction plan, clarify the division of responsibilities and requirements for construction steps. Provide training on operating procedures and personal protective equipment usage methods for construction personnel to ensure that each worker is proficient in operating skills. Prepare protective equipment such as hats, shoes, gloves, goggles, straps, etc., and ensure that their quality meets relevant standards. For high-altitude work areas, stable scaffolding or guardrails should be erected to ensure that construction personnel have a work platform. Construction personnel must wear straps when working at heights and ensure that the straps are connected to reliable fixing points. During the construction process, electrical regulations should be strictly followed to prevent electric shock accidents. Ensure good grounding of electrical equipment in the construction area, use insulated tools for operation, and avoid direct contact with live objects. Isolate the construction area, set up clear warning signs and lights to prevent non construction personnel from entering the construction area. Special markings should be placed on hazardous areas to alert construction personnel to potential hazards. Timely clean up construction waste and debris, keep the construction site clean, and prevent any impact on the normal use of cable trays. Classify and store construction waste and waste materials, and handle them properly according to relevant regulations. After installation, the cable tray should undergo quality inspection to check its flatness, installation quality, and appearance for compliance with requirements. Organize the records during the construction process, including construction plans, construction drawings, acceptance records, etc., to provide reference for subsequent maintenance and management. Fix all cables on the cable tray and label them with numbers for easy maintenance and management in the future. Take protective measures for cables, such as using cable protective covers, fireproof coatings, etc., to improve the durability of cables. Regularly inspect the installed cable trays, check for looseness, detachment, rust, and other issues, and promptly carry out maintenance and upkeep. Regularly clean and maintain cable trays to ensure they are in good working condition. Provide regular education and training to management and construction personnel to enhance their awareness and operational skills. Through training, managers and construction personnel can correctly identify and handle potential hazards to ensure construction. In summary, the protective measures for the installation site of ladder type cable trays involve multiple stages such as preparation before construction, installation process, and post installation. By taking these measures, construction personnel can be guaranteed, project quality can be improved, and potential hazards can be prevented.

Before the construction of trough cable trays, strict requirements must be strictly followed to ensure project quality and long-term stability. The bridge frame, connectors, and accessories must comply with the current national technical standards, and the anti-corrosion type and specifications must be consistent with the design requirements. The thickness and structural strength of the board must meet the load requirements. It is necessary to draw a routing diagram in advance, indicating the coordinates and elevations of the starting point, turning point, branch point, to ensure that the path is free of interference. Fill rate of 50%, width>0.1 meters to ensure ventilation, heat dissipation, and cable layout space. Measure the preset path, remove obstacles, estimate the load, and develop a construction plan. When entering indoors from outdoors, the slope is 21/100. Installation height of 22.2 meters, top distance from obstacles ≥ 0.3 meters, parallel laying time distance ≥ 0.6 meters. The verticality deviation of the bracket is 1.5mm/m, the levelness deviation is 3mm/m, and the straightness deviation of the entire length is ≤ 5mm. Supporting connectors are required for turning, tees, and other nodes, with bolt torque greater than 25N. m and complete anti loosening parts. The spacing between brackets should be 1.5-3.0 meters horizontally and ≤ 2.0 meters vertically, and the length should comply with the specifications to avoid deformation. Each bracket is firmly fixed, fixed every 2 meters when the cable is tilted>45 °, and fixed every 5-10 meters when laid horizontally. Sealing materials with a fire resistance of 21 hours are used at the crossing of the fire compartment. When the total length of the metal bridge is 30 meters, there should be at least 2 grounding points. For long-distance bridges, grounding should be done every 30-50 meters to ensure reliable bridging. Construction personnel must hold certificates and work strictly according to the drawings and standards. Welding and fastening parts require special inspections. After installation, clear markings should be sprayed and rows of cable trays should be neat and uniform. Load testing and ground connectivity testing are inspection items. The strict requirements before the construction of cable trays in trough type include material compliance, precise design, process control, and protection, which need to be implemented in combination with specifications and on-site measured data. Any oversight may lead to structural failure or hidden dangers, therefore full supervision and retention of acceptance records are required throughout the process.
