With the development of the times, cable trays are widely used, but we believe many people are not familiar with their wiring rules. Next, our company will introduce them to you!

The selection of cable tray materials is another crucial issue in cable tray laying construction. It is necessary to adjust the material of construction supports according to actual construction conditions. So, during the installation of cable trays, what construction requirements should we follow for cable tray materials? And what types of scaffold materials are available for selection?

A traditional and age-old method is painting. By applying paint to the tray surface, a protective layer is formed to isolate the tray from natural elements, preventing rust. However, paint is prone to peeling and requires reapplication later, resulting in high long-term costs.

In harsh corrosive environments, channel cable trays provide excellent shielding and protection for cables. As a fully enclosed type of cable tray, they are suitable for high-sensitivity systems such as control cables, instrumentation cables, and thermocouple cables.

The connection resistance between the two ends of the tray shall not exceed 0.00033 ohms, and the insulation coating on grounding holes shall be removed. In neutral-point grounded systems with a voltage of 1KV and below, the grounding of powered equipment shall be connected to the neutral line grounding of the system. When installing power cabinets with local power cutoff functions, the longitudinal cross-sectional area of the metal part of the tray shall not be less than the specified value.

As society continues to progress, electricity plays a vital role in human survival. To ensure the stable transmission of electricity, in addition to strict requirements for cable materials, cable trays also provide comprehensive protection for cables. Whether in computer rooms, basements, or industrial sites with high requirements, cable trays are widely used. Below, galvanized cable tray wholesalers provide a popular science overview of cable trays.

Below, Dexian Metal Products Co., Ltd. introduces the common types of cable trays: 1. Hot-Dip Galvanized Cable Trays Suitable for harsh acid-base and humid environments, featuring excellent corrosion resistance and a long service life. The relative cost is slightly higher.

Today, the global manufacturing industry is accelerating its restructuring. Localized production, globalized quality standards, comprehensive services, and intellectual property protection are the four major trends for world-leading cable tray manufacturers. These trends will shape the future direction of domestic steel cable tray companies, bringing profound transformations to the industry.

People usually have a one-sided understanding of cable trays. In fact, cable trays feature an aesthetic appearance, simple structure, flexible configuration, and convenient maintenance. Below, Dexian Metal Products Co., Ltd. will introduce the grounding treatment methods for galvanized cable trays.

Many people feel confused when selecting cable trays and don’t know how to choose. In fact, the selection of cable tray models is extremely important. Next, our company will detailedly introduce relevant knowledge about cable trays! We believe understanding this will be of great help to you.

Cable trays have been used in China for only over a decade, while in developed countries like Europe and the United States, their application dates back several decades. In a computer room project, compared to expensive high-tech software and hardware, cable trays are relatively simple and rarely receive much attention. However, they are an indispensable part of the entire wiring project.

With the advancement of modern science and technology in China, the manufacturing technology of powder-coated cable tray factories has continuously innovated. Enterprises have strengthened quality management, further improving their production technology and creating favorable conditions for the industry's development. The application of cable tray technology in wiring for numerous dense cable circuits has significantly increased the number of cables that can be accommodated. It not only protects cable lines but also effectively mitigates drawbacks such as electromagnetic interference and fire hazards, bringing convenience and benefits to cable construction and installation.

Currently, test reports for hot-dip galvanized sheet cable trays issued by nationally recognized testing institutions are also based on JB/T 10216-2013. This standard specifies that the "surface protection layer thickness" shall be ≥ 65 μm. However, even if a thickness test is conducted (e.g., a result of 12 μm), no qualification judgment will be made for such cases.

Some people believe they are the same, while others argue they are completely different. Since there are no clear terms or definitions in relevant cable tray standards, no one can provide convincing evidence to persuade the other side. To understand this issue, we can start with the concepts of "hot-dip galvanizing" and "hot galvanizing."

There is a wide variety of cable trays with inconsistent names across relevant standards, but the terms "tray" and "ladder" have been basically retained. On this basis, some standards have further subdivided categories, such as perforated trays, non-perforated trays, and wire mesh trays. During the construction of cable trays, various issues arise, including product selection and standard implementation.
