A solid cable tray and a wire mesh cable tray are both used to hold and protect electrical wires, network cables, air hoses, water pipes, and similar lines in electrical systems, networking systems, cooling systems, and more. However, there are several key differences between a solid cable tray and a wire mesh cable tray. 1. Design Solid-bottom cable trays typically have a rigid structure with a flat, closed top surface and more angular bends. Wire mesh cable trays, on the…

Knowing how to choose the right cable tray matters, since there are many types on the market, made from different materials and with different surface finishes. As you research, you will come across products such as powder-coated cable trays, hot-dip galvanized cable trays, and more. So which type is right for your project? Here is a practical guide to choosing the right cable tray for your needs. Types of Cable Trays Guide to Choosing Indoor Cable Trays The cable tray…

Which cable tray and ladder standards apply to your project? What standards are most commonly referenced in Vietnam? In this article, The Sun’s cable tray team walks through the cable tray and ladder standards most commonly applied in Vietnam. Note that export products sometimes require additional, customer-specific standards, which are outside the scope of this article. Common Cable Tray and Ladder Standards TCVN (Vietnam Standard): Issued by the Directorate for Standards, Metrology and Quality under Vietnam’s Ministry of Science and…

IEC 61537 is an international standard on cable management. The current edition is IEC 61537:2023, titled Cable management – Cable tray systems and cable ladder systems. Overview of IEC 61537 IEC 61537:2023 specifies requirements and tests for cable tray systems and cable ladder systems intended to support and provide space for cables, and possibly other electrical equipment, in power and/or communication installations. Where needed, cable tray or cable ladder systems may also be used to group cables together. This document…

Electrostatic powder coating is a widely used finishing method across many industries. It is regarded as one of the most effective coating processes for protecting a product’s surface while also improving its appearance. This article explains what electrostatic powder coating is and looks at its main applications, including in cable trays and electrical enclosures. I. What Is Electrostatic Powder Coating? 1. Concept Electrostatic powder coating is a coating process built on the electrostatic attraction between paint particles and charged ions.…

Hot-dip galvanizing is one of the most widely used corrosion-protection methods for steel components, including cable ladders. This article explains what hot-dip galvanizing is, the safety considerations involved, how it protects steel, and why it is such a popular finish for cable ladders used in construction, power, and industrial projects. What Is Hot-Dip Galvanizing? Hot-dip galvanizing is the process of coating iron or steel with a layer of zinc. The metal is immersed in a bath of molten zinc at…

Industrial construction projects rely on strict, standardized rules for how power and control cables are routed, supported, and protected. In Vietnam, these rules are codified in the National Standard TCVN 9208:2012, which governs the design and installation of electrical cable systems in industrial and civil works. This article summarizes the standard’s scope, key terminology, and its most important practical requirements for engineers, contractors, and facility owners working with cable trays, cable ladders, wire mesh trays, conduit, and direct-buried cable. Scope…

The material used for a wire mesh cable tray has a direct effect on its price. There’s a wide range of materials to choose from, but two are by far the most common: hot-dip galvanized steel and 304 stainless steel. So what are the pros and cons of each, and which applications does each suit best? Let’s find out in this article. 1. Hot-Dip Galvanized Steel Advantages: Lower cost: Compared with 304 stainless steel, hot-dip galvanized steel is considerably cheaper,…
