The products of cable tray factories are increasingly widely used in the construction industry. What are the bridge construction forms they have? It has both the toughness of fiberglass cable trays and the rigidity of metal cable trays, with high mechanical strength, suitable for use in long spans, strong corrosive environments, and heavy load conditions. It can be divided into three types: tray type cable tray, trough type cable tray, and trapezoidal cable tray.   The tray type cable tray has a beautiful appearance, light weight, simple structure, and convenient installation, making it suitable for the laying of control cables and the installation of power cables; The trough type cable tray is suitable for laying thermocouple cables, communication cables, computer cables, as well as protecting cables in heavily corrosive environments, and has good effects. It is a fully enclosed cable tray; The trapezoidal cable tray has a unique shape, light weight, low cost, easy installation, good ventilation and heat dissipation performance, and is suitable for laying high and low power cables.

When selecting cable trays, it is important to first consider the material selection for cable tray production. It is advisable to make high-quality steel plates, and the toilet surface should be treated with anti-corrosion measures such as spraying and galvanizing to increase its anti-corrosion performance and prolong its service life, meeting the needs of the working environment. If there is a high requirement for cleanliness or a highly corrosive environment, it is recommended that you choose aluminum alloy cable trays. Secondly, it is the performance of anti electromagnetic interference. In order to reduce electromagnetic interference, it is better to choose enclosed or semi enclosed cable trays. For example: trough type cable tray. Later on, we also need to consider its safety, availability, and economy in order to determine a more suitable solution, which is also beneficial for cable maintenance and repair after construction is completed.

When installing indoors, in order to ensure the flatness, aesthetics, and uniformity of the cable tray, its horizontal load deformation should generally be controlled within 4 millimeters. We can search for the corresponding structural form of the cable tray load characteristic curve based on the selected cable tray width and the required horizontal load deformation of the cable tray. If the deformation requirements cannot be met, the side height of the cable tray can be appropriately increased or the support spacing can be reduced to meet the requirements. Cable tray is made of thin steel plate stamping, with limited bearing capacity. It will deform due to overloading of the tray, which not only affects the appearance of the tray, but also affects the safe operation of the cable. In general, the bearing capacity of cable trays is represented by the load characteristic curve of cable trays. From the load curve graph, it can be seen that the magnitude of its load capacity is related to the specifications and support distance of the cable tray, corresponding to the same support distance and bending convex deformation. The side height is high and the bearing capacity is large. When the load capacity is the same, the bending deformation of cable trays of the same specification with small support distance is small. We all know that the load of cable trays is mainly divided into three aspects: load, dynamic load, and additional load. So, what are the specific differences and characteristics of these three types of loads? In fact, static load refers to the various types and numbers of cables laid in cable trays, as well as the outer diameter weight/unit length of each cable. These basic parameters must be strictly calculated according to the different routes of cable laying. Dynamic load refers to the weight of construction and maintenance personnel during the installation and maintenance process of cable trays. In fact, for light cable trays, we generally do not consider dynamic load, which means that it is not allowed to stand on the tray. If it is necessary to consider the situation of standing people, the span should be appropriately reduced. The additional load only refers to the load formed by ice, snow, wind, and electromagnetic forces outdoors, which is related to the natural meteorological conditions of the installation site and the properties of the charged body. Corresponding calculations should also be made in the design based on their conditions.

The measurement of bridge cables mainly involves the following aspects:   1. Size measurement: Firstly, it is necessary to determine the size of the cable tray, which is usually selected based on the size requirements of the required installation environment. Generally speaking, the size of cable trays is determined through measurement or estimation.   2. Load capacity calculation: Based on the size of the cable tray and the required load, its load capacity can be calculated. Usually, the load capacity of bridge cables is calculated based on specific standards and specifications.   3. Cable path inspection: Before installation, it is necessary to check the path of the cable tray, including any obstacles, corners, lengths, etc. along the path. This can help determine the shortest path for bridge cables and ensure that they can run smoothly throughout the entire path.   4. Tensile testing: To ensure that the cable tray can withstand the expected load, tensile testing is usually required. This test can detect the strength of bridge cables and any potential issues.   5. Installation quality inspection: After installation is completed, it is necessary to check the installation quality of the bridge cable, including the stability of the bridge, whether the cable is laid flat, and whether it is firmly fixed.   Overall, the measurement of bridge cables is a comprehensive process that requires comprehensive consideration of multiple factors such as size, load capacity, path, tensile testing, and installation quality. Only by fully considering and taking appropriate measures during this process can the safety and reliability of bridge cables be ensured.

Cable tray refers to a device that supports and protects cables, usually made of materials such as metal or plastic. It is mainly used for electrical wiring in buildings, especially in large buildings and complex electrical systems. The function of cable trays is to protect cables from mechanical damage, such as friction, collision, etc. Meanwhile, it can also provide good electrical grounding for cables and facilitate their installation and maintenance. There are many advantages to using cable trays in building electrical wiring.   Firstly, it can provide reliable electrical grounding to ensure the safety and stability of the electrical system. Secondly, it can protect cables, prevent mechanical damage, and extend their service life. In addition, cable trays can improve the quality and efficiency of electrical wiring, reduce the difficulty and cost of cable installation and maintenance. When using cable trays, the following points should be noted.   Firstly, it is necessary to select the appropriate cable tray type and specifications based on the specific building environment and electrical requirements. Secondly, it is necessary to ensure the installation quality and reliability of cable trays to avoid safety issues. In addition, regular inspections and maintenance of cable trays are also necessary to ensure their normal operation and service life.   In short, cable trays are an important electrical equipment and protection tool, which have a wide range of applications and roles in building electrical wiring. When using, attention should be paid to its characteristics and usage methods to ensure the safety and stability of the electrical system.
