Characteristics of Aluminum Alloy Cable Tray

1. Aluminum alloy cable trays have a beautiful appearance, high load capacity, light weight, and can be made into various styles. Due to their excellent corrosion resistance, they are widely used in power plants, chemical, petrochemical and other fields, especially in places with harsh corrosive environments.

2. Aluminum alloy cable trays have some aluminum alloys processed by heat treatment, which have good mechanical properties and can be processed into various forms and specifications of aluminum materials.

3. The ladder edge and crossbar are made by extrusion molding process, making the appearance of the bridge smooth and beautiful.

4. The maturity of processing technology and connection methods makes the installation of cable trays convenient.

The function of aluminum alloy cable tray

Function 1: It can have a good decorative effect. The style and type are already very good when designing, and if we can all know the basic advantages and values, we can also check whether the products produced by the aluminum alloy bridge factory are what we want when making specific choices. Indeed, they can be easily selected and used.

Function 2: It has a good overall display effect and can be effectively used in many places. However, many people are still concerned about the price of aluminum alloy cable trays. If the price is reasonable and the overall size is what they want, they can easily choose and use them.

Cable trays can be independently erected or laid on various buildings and pipe gallery supports, reflecting the characteristics of simple structure, beautiful appearance, flexible configuration, and convenient maintenance of building structures. All parts of the bridge frame need to be galvanized and installed outdoors outside the building. If it is located near the seaside or in a corrosive area, the material * * * has the characteristics of anti-corrosion, moisture resistance, good adhesion, and high impact strength.

Advantages of Aluminum Alloy Bridge:

The aluminum alloy bridge adopts 1060 aluminum plate, which is a commonly used series in the aluminum plate family. The 1060 aluminum plate has a high aluminum content of 99.6% and is suitable for installation and laying in humid environments. It has great advantages in conductivity, thermal conductivity, and corrosiveness, meeting the requirements of conventional processing. Its characteristics are rust prevention, corrosion resistance, long service life, and aluminum alloy material has a relatively light weight, which can improve the installation efficiency of construction personnel.

Principle of Aluminum Alloy Bridge:

Aluminum alloy cable trays are produced using aluminum alloy profiles, and are a general term for alloys based on aluminum. The main alloying elements are copper, silicon, magnesium, zinc, manganese, and the secondary alloying elements are nickel, iron, titanium, chromium, lithium, etc.

Aluminum alloy has low density, but high strength, close to or exceeding high-quality steel, good plasticity, and can be processed into various profiles. It has excellent conductivity, thermal conductivity, and corrosion resistance, and is widely used in industry, with a usage rate second only to steel

Introduction

A cable tray is a bracket that supports and holds cables. Cable trays are commonly used in engineering, as long as cables are laid. Cable trays are a supporting project for wiring engineering, and there is currently no specialized specification guidance. The specifications and programs of each manufacturer lack universality. Therefore, the design and selection process should be based on the type and quantity of cables in various weak current systems to reasonably select suitable cable trays. Cable trays have the characteristics of wide variety, wide application, high strength, light structure, low cost, simple construction, flexible wiring, standard installation, and beautiful appearance. Aluminum alloy bridge is made by extruding aluminum alloy, which has the characteristics of beautiful appearance, simple structure, and easy installation.

Aluminum alloy cable tray is suitable for overhead laying of power cables and electrical equipment wires indoors and outdoors in general industrial and mining enterprises, and can also be used as a channel for telecommunications cables and self-control conduit cables.

Aluminum cable trays are divided into three types: trough type, tray type, and step type.

1. Trough type bridge: It is composed of two columns supported on the crossbeam, and one end is connected to each branch with accessories such as bends or tees. The other end is supported on a wall or column (Figure 1), and the entire system can be replaced with the same column to meet construction requirements;

2. Tray type: consisting of a base, bracket, and cover plate, it can be horizontally tilted to any part of the building;

3. Cascade (or grid format): A structure composed of multiple short materials combined into a group with side supports as supporting components, forming a grid like support structure fixed at different points to achieve wiring functions in multiple directions Customize various specifications of trapezoidal cable trays according to the engineering site environment and customer requirements

Structural form of bridge:

1. In engineering design, the layout of cable trays should be comprehensively compared based on factors such as economic rationality, technical feasibility, and operational safety to determine the plan. It should also fully meet the requirements of construction, installation, maintenance, and cable laying.

2. When the bridge is laid horizontally, the height from the ground is generally not less than 2.5m. When laid vertically, the part below 1.8m from the ground should be protected with a metal cover plate, except when laid in an electrical dedicated room. Cable trays laid horizontally in equipment compartments or raceways and below 2.5m should be protected with grounding measures.

3. Bridges, cable trays, and their supports and hangers used in corrosive environments should be made of corrosion-resistant rigid materials. Alternatively, anti-corrosion treatment can be adopted, and the anti-corrosion treatment method should meet the requirements of the project.

4. In sections with fire protection requirements, cable trays can be equipped with fire-resistant or flame-retardant materials such as boards and nets to form enclosed or semi enclosed structures, and measures such as applying fire-resistant coatings to the surfaces of cable trays and their supports and hangers can be taken.
