      What Are Cable Tray Systems

      Definition and Function

      Cable Tray Systems help hold and organize cables in buildings. They make a clear path for power, data, and control cables. You can put them on ceilings, walls, or floors. This helps you move cables where you want them. Cable Tray Systems stop cables from getting tangled and messy. There are different designs like ladder, solid bottom, or perforated trays.

      Cable Tray Systems are not the same as other cable holders:

      • Their open design lets air move around and makes cables easy to manage.

      • You can check or fix cables fast.

      • They are good for places where heat needs to escape.

      • They do not trap heat like enclosed trunking, so cables stay cooler.

      These systems hold insulated cables for power and data. They also keep cables safe from weather and dirt, especially where many people walk.

      Key Benefits

      Cable Tray Systems have many good points:

      • They are quick to put in, so you save time.

      • Open trays make it easy to fix or change cables.

      • You can add or move cables if you need to.

      • You spend less money because they are fast to install.

      • Air moves well, so cables do not get too hot.

      • Cables stay neat and safe from tangling.

      • You can pick the right tray for your job, like heavy-duty ladder trays for big jobs.

      Tip: Keep cables neat and easy to reach for better safety and work.

      Cable Tray Systems are a strong way to handle cables in many places. You can count on them to keep your cables safe and working well.

      Types of Cable Tray Systems

      When you choose Cable Tray Systems, you need to know the main types. Each type has special features. You can pick the best one for your project by looking at the material, design, and size.

      By Material: Steel, Aluminum, Fiberglass

      You will find three main materials in Cable Tray Systems: steel, aluminum, and fiberglass (also called GRP). Each material works best in different places.

      • Steel gives you strong support. You use it in heavy-duty jobs. Steel is the most common material for cable trays. It is tough but can rust if you do not protect it.

      • Aluminum is light and easy to carry. It does not rust easily. Aluminum trays are popular in buildings and make up more than 40% of the market. You can use them where you need to move trays often.

      • Fiberglass (GRP) is very light and does not rust. You use it in places with chemicals or outside in the weather. It lasts a long time and needs little care.

      Here is a table to help you compare these materials:

      Ningbo Pudeli Cable Tray Co., Ltd. makes all these types. You can find stainless steel, hot-dip galvanized, and spray-coated trays for extra protection. You can also get fire-resistant trays for special safety needs.

      By Design: Ladder, Wire Mesh, Solid Bottom, Trough, Channel, Single Rail

      The design of your tray changes how you use it. You can pick from several shapes and styles.

      • Ladder trays look like ladders. You use them for heavy cables. They let air move around the cables and make it easy to add or remove wires.

      • Wire mesh trays use a grid of wires. You use them for light cables, like in data centers. They are easy to cut and shape.

      • Solid bottom trays have a flat base. You use them when you need to protect cables from dust or dirt.

      • Trough trays have small holes or slots. They give some airflow and keep cables safe.

      • Channel trays are small and fit in tight spaces. You use them for short runs or single cables.

      • Single rail trays use one strong bar. You use them for special jobs where you need to save space.

      Here are two important standards you should know:

      NEMA Standard

      Description

      NEMA VE 1

      Sets rules for how trays are made and tested.

      NEMA VE 2

      Gives tips for installing trays, like how far apart to put supports.

      Ningbo Pudeli Cable Tray Co., Ltd. offers many designs. You can find ladder-type, tray-type, trough-type, and wire mesh trays. You can also get advanced options like fire-resistant and galvanized trays.

      Tip: Pick the design that matches your cables and the place you will use them.

      By Size and Load Capacity

      You need to match the size and strength of your tray to your cables. Trays come in many widths, depths, and thicknesses. You can find trays for small wires or big power cables.

      Here is a table showing common cable types and sizes:

      Cable Type

      Voltage Rating

      Gauge Range

      Tray Cable (TC)

      Up to 600V

      18 AWG to 4/0 AWG

      Instrumentation Tray Cable (ITC)

      300V

      22 AWG to 16 AWG

      Power Limited Tray Cable (PLTC)

      Low-energy

      22 AWG to 16 AWG

      You should check the load rating before you buy. Some trays hold heavy cables. Others work best for light wires. You can ask the manufacturer for help if you are not sure.

      Ningbo Pudeli Cable Tray Co., Ltd. can make trays in many sizes. You can also ask for custom trays to fit your project.

      Remember: Always check the load and size before you install your tray. This keeps your cables safe and your system strong.

      Applications of Cable Tray Systems

      Pros and Cons of Tray Types

      Material Advantages and Limitations

      You need to know what each cable tray material can do. Steel, aluminum, and fiberglass each have their own strengths and weaknesses. The right choice depends on your project needs.

      Here is a table to help you compare:

      Material

      Advantages

      Limitations

      Steel

      – Handles heavy cables well.
      – Easy to shape for custom jobs.

      – Rusts in wet places.
      – Heavy, so costs more to move and install.

      Aluminum Alloy

      – Light, so you save on installation.
      – Fights rust for 15-20 years.

      – Costs more than steel.
      – Not as strong for very heavy cables.

      Fiberglass (FRP)

      – Does not conduct electricity.
      – Resists fire and chemicals very well.

      – Not as strong as steel or aluminum.

      Tip: Use steel for heavy loads, aluminum for light weight and long life, and fiberglass where you need insulation and chemical safety.

      Design Strengths and Weaknesses

      You also need to think about the tray design. Each design solves different problems on the job site.

      • Prefabricated components make installation faster. You spend less on labor and finish the job quickly.

      • Modular designs help you add more cables later. You can build fast and know exactly how much material you need.

      • High-capacity trays like the Mega Snake® series let you mount and connect many cables in one place. You save time and get strong support.

      • Concealed trays such as the Snake Canyon® series fit under raised floors. You do not need special tools, so you can set them up fast.
