Cable tray is an important equipment for cable laying and management, and is widely used in buildings, industrial facilities, data centers and other places. The following is a detailed analysis of cable tray:
1. Definition and function
Cable tray refers to a bridge-like structure made of metal or non-metallic materials for installing and supporting cables. It plays the role of fixing, protecting and organizing cables, which can effectively reduce the cost of cable laying and improve maintenance efficiency. Specific functions include:
Support and fix cables: fix the cable lines at high altitudes to avoid contact with the ground or other facilities, thereby ensuring their safety and stability.
Separate cables: Through different types of cable trays, cables can be separated by type or power, which is conducive to management and maintenance.
Protect cables: provide certain physical protection to prevent cables from being damaged or malfunctioning due to external reasons, and ensure the safety of the entire system.
Neat and beautiful: make the cable lines orderly and uniformly wired, so that the entire system looks neat and beautiful, easy to maintain and manage. |
2. Type and Material
Type
Cable trays are of various types, mainly including the following:
Ladder-type tray: It has the advantages of light weight, low cost, unique shape, easy installation, good heat dissipation and good air permeability. It is suitable for the laying of cables of general diameter and high and low voltage power cables.
Tray-type tray: It is widely used in petroleum, chemical industry, light industry, telecommunications, etc. It has the advantages of light weight, large load, beautiful appearance, simple structure and easy installation. It is suitable for installing power cables and control cables.
Trough-type tray: It has a special structure and has its unique advantages and application scenarios.
Long-span tray: It is suitable for places that need to span a large distance.
Combined tray: It can be flexibly combined according to actual needs to meet complex wiring needs.
Material
Cable trays are made of various materials to adapt to different use environments and needs, mainly including:
Steel tray: It is used more frequently, has high strength and rigidity, and can withstand large loads.
Stainless steel tray: It is very corrosion-resistant, impact-resistant and not easy to rust. It is suitable for harsh environments such as humidity, acid and alkali.
Aluminum alloy bridge: light weight, high strength, good corrosion resistance and conductivity, strong anti-electromagnetic interference ability, but generally suitable for indoor environment.
Glass fiber reinforced plastic bridge: has good corrosion resistance and insulation performance, suitable for humid, acidic and alkali and other harsh environments, and light weight and easy installation.
Plastic, PVC bridge: light weight, corrosion resistance, good insulation performance, suitable for occasions with low weight requirements.
Polymer bridge: has the characteristics of steel and toughness, excellent corrosion resistance, suitable for different climatic environments and chemical corrosion environments. |
3. Installation and maintenance
The installation of cable bridges must follow a certain construction sequence and key points, including measurement and positioning, support and hanger production and installation, bridge installation, grounding treatment and other steps. During the installation process, attention should be paid to coordination with various professionals to avoid conflicts with other pipeline equipment.
The maintenance of cable bridges is also very important, which can extend their service life and ensure the normal operation of the cable system. The main maintenance measures include regular cleaning, inspection, repair of damaged parts, keeping dry, preventing heavy pressure, regular lubrication, etc. |
4. Notes
When selecting a cable tray, the type and specification must be determined based on the cable load and the environment where the tray is installed.
During the installation process, relevant standards and specifications must be followed to ensure safety and quality.
Maintenance work should be carried out regularly, and maintenance records should be established to promptly detect and solve problems. |
