Advantages of Cable Tray

  • Ease of Installation and Maintenance

    Compared to conduit systems, cable trays are much simpler to install. They allow quick access to cables, making it easy to add, move or change cables without a lot of disassembly.

  • Cost-effective

    In many cases, cable tray installations are more cost-effective than other cable management solutions due to shorter installation times and potentially less material used.

  • Flexibility and adaptability

    Cable trays are highly adaptable to different routes and can be easily reconfigured to accommodate changes in cable layout.

  • Excellent cable protection

    Cable trays protect cables from physical damage, moisture, dust and other environmental hazards by keeping them off the ground and in an organized manner.

  • Improved airflow and heat dissipation

    The open design of the cable tray promotes airflow around the cables, which helps dissipate the heat generated by the cables.

Cable Tray Fittings Classes

Construction

Cable trays are necessary for organizing and protecting electrical cables in buildings, from high-rise offices to residential complexes.

Manufacturing Plants

In factories, cable trays manage the complex network of power and control cables that keep production lines running.

Data Centers

The ever-growing demand for data necessitates efficient cable management solutions. Cable trays provide proper organization and airflow for sensitive data cabling.

Power Plants

Safety and reliability are crucial in power plants. Cable trays play a crucial role in managing high-voltage cables efficiently.

Cable Tray Fittings Classes

Class 1

Designed for use with NEMA Classes 12B and 12C cable trays. These systems have 1 1/8" wide side rail flanges and 4-hole splice plates.

Class 2

Designed for use with NEMA Classes 20A, 20B, and 20C cable trays. These systems have 2" wide side rail flanges and 4-hole splice plates.

Class 3

Designed for use with NEMA Classes that exceed 20C. These systems have 2 3/8" wide side rail flanges and 8-hole splice plates.

Class 4

Designed for use with A820E cable tray systems, which are 8" high. These systems have 2 3/4" wide side rail flanges and 8-hole heavy-duty splice plates.

Cable Tray Installation Requirements

Follow the manufacturer's instructions, industry standards, and local electrical codes while installing cable trays.

Make sure to use correct support spacing, secure fastening, specific types of cable isolation, and regular inspections.

Depending on the installation location, choose cable trays suitable for either indoor or outdoor use.

Identify the types and quantity of cables that need to be routed through the cable trays. Consider future expansion needs to accommodate additional cables.

Clean the area where the cable trays will be installed, removing any debris, dust, or obstacles that could hinder the process.

Ensure all sections of the cable tray are adequately bonded together to maintain continuity and prevent potential differences.

Check for any loose connections, misalignment, or damages to the cable trays and cables.

Conduct a load test to verify that the cable trays can bear the weight of the cables without any signs of stress or deformation.

Safety Relay Applications

01/

Material preparation

The manufacturing process of galvanized cable tray firstly requires the preparation of materials. At the same time, it is also necessary to prepare certain specifications and lengths of steel strip, steel pipe and other accessories.
03/

Bending

This step is usually done by hydraulic bending machine or roll bending machine. According to different design requirements, different bending angles and section shapes can be selected.
05/

Surface treatment

After the welding is completed, the galvanized cable tray needs to be surface treated.
07/

Packaging and transportation

The galvanized cable tray which passes the quality inspection needs to be packed to prevent damage during transportation. Usually use cartons, wooden boxes or pallets and other ways to pack.
02/

Processing and cutting

The prepared steel plate is cut, according to the design requirements and the required size into the corresponding plate. This step is usually carried out by mechanical equipment such as shears and cutting machines.
04/

Welding

Usually use electric welding or gas welding way to carry out. During the welding process, it is necessary to ensure the quality and firmness of the welding seam to ensure the stability and safety of the cable tray.
06/

Quality testing

The quality inspection includes size check, strength test, corrosion resistance test, etc. Only through the quality inspection products can be sold and used.

Quality Assurance in Our Cable Tray Manufacturing

Selection of High-Quality Materials: The process begins with the procurement of superior materials that are apt for the specific type of cable tray being manufactured. This choice is pivotal as the quality of raw materials, known as material selection, significantly influences the overall quality of the final product.

Testing and Inspection during Manufacturing: Throughout the production process, the cable trays are subjected to rigorous cable tray testing and inspection. This stage is crucial for identifying any defects or inconsistencies. Additionally, we perform electrical testing to verify the cable tray’s ability to withstand the specified electrical safety loads.

Final Quality Testing: Once the manufacturing process is complete, the cable trays undergo a final series of exhaustive tests. These tests often simulate extreme operational conditions including high voltages, varying temperatures, and physical stresses to assess the product's endurance and performance under challenging scenarios.

Compliance with Standards: Cable tray quality assurance : also involves ensuring compliance with national and international standards. This compliance is not only a regulatory requirement but also a testament to the electrical safety and reliability of the cable trays.

Continuous Monitoring and Improvement: The cable tray quality assurance process is not just limited to the production phase but is a continuous cycle. Feedback from cable tray testing, customer inputs, and market trends are regularly analysed for continuous improvement in product quality and manufacturing processes.
