Cable Tray Purchasing and Cable Tray Roll Forming Machine

Company with the continuous growth of technology, the cable tray roll forming machine has a good performance in electrical industry. Cable frame forming machine has been continuously adjusted in details to give users a good experience. Therefore, the roll forming machine has been recognized, and the cable channel forming machine is also continuously seeking technological breakthroughs, the metal forming machine process cable tray has become the product that people rely on.
 In what ways does the cable tray roll forming machine have a good performance? To what extent can it be made?


As a common construction auxiliary structure, the cable tray roll forming machine is widely used in various industries. As long as it is necessary to lay cables, it is usually indispensable. The cable bridge forming machine not only plays the role of supporting the cable, but also protects the cable. And it is divided into multiple types according to needs and environment. Below we will take a look at the common categories and the characteristics of various types.
1. Tray-type cable tray forming machine, Tray-type is a common type in various categories of cable trays. Tray-type cable trays usually have a relatively small weight, but their load carrying capacity is very large. The pallet type usually has a simple structure and can be installed easily. Therefore, it is often used in the petrochemical and light industrial industries with a large construction area, and is suitable for installing power cables.
2. Slotted cable tray forming machine, This type of cable tray is widely used. As the name implies, the slotted cable tray is a trough, which is a kind of bridge structure that wraps cables in it. The strong ability can also effectively prevent the external environment from corroding and damaging the cable, so it is commonly used in the computer industry or communication industry with high requirements, as well as other industries with strong environmental interference.
3. Large-span cable tray forming machine, The most prominent feature of the large-span cable tray is that the length of the unit number of the bridge is very large, and the large one can reach several meters. Generally, the service life is relatively long, and the installation cost is low, and the installation is very convenient. It is often used for the installation of long-distance transmission cables, and its advantages are very obvious.
4. Ladder-type cable bridge forming machine, The most prominent feature is the small weight, easy installation, ventilation and durability, and good maintenance. It is often used in the installation of power cables such as high-voltage cables or low-voltage cables.
5. Combined cable tray forming machine, This is a new type of cable tray that is flexible and convenient to install, suitable for many different environments. Among various types of cable trays, the combined application is the most extensive.



Selection of purchasing cable tray
1. Selection of cable bridge structure type
In engineering design documents, cable trays are generally referred to as "brackets", and no specific structural features are indicated. The price of cable trays of different types and different production materials varies greatly, and the confusion of structural types will cause heat dissipation at the work site. 1. Problems with mechanical protection. Therefore, in the design stage, designers should be required to reasonably select the structural characteristics of the cable tray according to the characteristics of the engineering environment and technical requirements, and clearly express them in the model designation and material table of the plan.

  2. Cable tray material selection
The material of cable tray is another common problem in cable tray engineering design. According to the division of materials, cable trays are mainly made of steel, glass steel and aluminum alloy. The characteristics of glass fiber reinforced plastic cable trays are light weight and the specific gravity is only 1/4 of carbon steel; good water resistance and corrosion resistance, suitable for chemical plants. It is not easy to burn, and the oxygen index of the flame-retardant fiberglass cable tray is ≥32. The service life is long, the general design life is 20 years, but the price is 3 times that of the steel cable bridge. The superiority of the construction is that it is easy to cut, flexible to assemble, and does not require hot fire for installation. This is especially important for chemical plant projects with explosive hazardous environments and tight construction schedules. Because in explosive hazardous environments, the chemical plant must be shut down during the installation of hot fire engineering, economical Benefits will be affected. The external dimensions and load characteristics of aluminum alloy cable trays are basically similar to those of steel bridges. In terms of cost, the cost of aluminum alloy bridges is 20% higher than that of galvanized steel cable bridges, and the service life is more than 5 times that of steel cable bridges.
