Tray type cable tray is a partially sealed option that closely resembles the galvanized trough type cable tray. It features small openings at the bottom to facilitate the release of heat. This cable tray is well-suited for laying control cables and communication cables, both horizontally and vertically. Additionally, it can be utilized for power cable installation.
Advantages:
The galvanized tray type bridge has excellent performance in shielding, providing effective protection against signal interference and dust. Its ability to withstand dust and dirt is exceptional, making it a highly desirable solution for such applications.
The simple and lightweight structure with a beautiful appearance makes the installation of this product very convenient. Its greatest advantage lies in the effective heat dissipation mechanism at the bottom, which enhances fire prevention capabilities. However, due to perforated bottom, the bearing capacity is limited and therefore the thickness of the plate must be fixed. Overall, this product is easy to use and has excellent fire prevention capabilities.
The aluminum alloy cable tray is acclaimed for its aesthetic appeal, uncomplicated design, one-of-a-kind style, remarkable carrying capacity and lightweight structure. It is rendered resistant to corrosion on account of the anodized surface, it also offers a shield against electromagnetic interference, particularly protective against shielding interference, making it unparalleled in comparison to steel cable trays. The aluminum alloy bridge plays a crucial role in contemporary industry, modern national defense and high technology tools, making it highly practical and valuable.
The properties of aluminum alloy materials are unique and distinctive. These alloys are lightweight, strong, corrosion-resistant, and exhibit high electrical and thermal conductivity. They have an outstanding strength-to-weight ratio, making them highly sought after in various industries. Additionally, aluminum alloys are ductile, malleable, and can be easily fabricated into different shapes and sizes, allowing them to be used in various industrial applications. Due to their exceptional properties, aluminum alloys are used in the production of aircraft, automobiles, and various household items.
Aluminum alloy possesses a lightweight and flexible nature, with a density of 2171 g/cm3 that is approximately one-third of steel's density (7187 g/cm3). Similarly, its Young's modulus is also about a third of steel's modulus, emphasizing its pliable characteristics.
The strength of aluminum is often a concern due to its low tensile strength compared to other materials such as low carbon steel. However, pure aluminum can be strengthened through heat treatment and alloying. For example, the commonly used material for aluminum alloy car body, 6005a-t6, has a minimum tensile strength of 360 Mn / m2, which is comparable to that of low carbon steel. This demonstrates that with the right treatment and alloying, aluminum can become a strong and reliable material for a variety of applications.
Aluminum alloy possesses various beneficial qualities and one of them is its good resistance against corrosion. As soon as it comes in contact with air, the surface of aluminum alloy undergoes a process wherein a dense oxide film forms and provides a barrier against corrosion. This oxide film serves as a protective layer, preventing the underlying metal from getting corroded. When the "alumina film treatment method" is applied to the alloy, it further enhances the corrosion resistance ability of the metal, making it highly reliable for industrial and household applications.
The profiles utilized for railway vehicles have exceptional extrusion capability and can be easily processed through secondary machining and bending, thus ensuring good processing performance.
One of the many benefits of aluminum is its easy regenerating capabilities. This is due to the fact that aluminum has a low melting point of 660 degrees, allowing for it to be easily melted down and formed into a new product. This capability is highly advantageous in terms of sustainability as it allows for the continuous repurposing of the material, reducing waste and increasing its lifespan. Its regenerating properties also contribute towards a more eco-friendly production process and ensure that aluminum can be used in a wide range of applications.
When selecting materials for aluminum alloy car bodies, it is important to follow certain principles. This includes taking into account the structure, manufacturing process, and application of the material. With careful consideration, an optimal material can be selected for the car body that is in line with these principles and meets all necessary requirements.
To meet the requirement of being lightweight, the material must possess excellent strength, weldability, extrudability, and ease of maintenance.
For extended service life, it is crucial to have high resistance to corrosion and appropriate surface treatment.
