Advantages of Using Tray Cables

When it comes to the most efficient management of the cable wires in any small or big industry, tray cables easily wins the race amongst its competitors. As opposed to most conventional systems which are still in use, tray cables are much more cost-effective and easier to maintain throughout their lifetime. It is probably the safest design which offer various safety advantages as compared to other systems.

What are tray cables?

Tray cables are the collection of insulated conductors that contains multiple layers of protecting cover, including non-metallic sheaths, a messenger wire, and supported by a tray to carry them. It is commonly used in major industries, substations, and different infrastructures with high power functions and requirements.

There are several different kinds of tray cables. It includes tray cable (TC), Power Limited Tray Cable (PLTC), Instrumentation Tray Cable (ITC), Metal Clad Tray Cable (MCTC), Mineral Insulated Tray Cable (MITC) and others.

Here is the list of advantages of installing a tray cable in any industry or infrastructure.

Sun Light Resistance

One of the major benefits of using a tray cable in any commercial building, chemical plants, or utility substations is its resistance to sun exposure. The conventional systems which were used before the arrival of tray cables were susceptible to sunlight. It used to create magnetic interference and affected the overall output in power lines.

Sustains Extreme Heat and Water Exposure

Tray cables are available in different varieties for various purposes. Tray cables installed in any industry depends on the kind of environment it is used in. Tray cables are well equipped with heat resistance layering and thus work well even when exposed to extreme heat conditions. The insulation layer of the tray cable is made up of thermoplastic heat and water-resistant nylon (THWN), which helps it in sustaining both the states. It also contains flame retardant ethylene propylene (FREP), which prevents it from catching fire.

Indoor and Outdoor Installation Superiority

In addition to sunlight and heat exposure, tray cables can easily be installed inside or outside any infrastructure. The multiple layers of tray cables protect it from unwanted the dissipation of voltage and data across the line in extreme weather conditions. Whether it is exposed to severe rains or frostbite winters, the tray cables perform well against the harshest conditions.

Works Underground 

In big industries, sometimes, it is not feasible enough to map all the electrical lines above the ground. In such cases, the tray cables are installed underground. The versatile nature of the tray cable allows it to work effectively, even when buried underground. It is free from magnetic interferences caused by other transmission lines when installing above the ground.

Produces comparatively less smoke

The traditional system of the tray cables used PVC (Polyvinyl Chloride) material as the outermost layer of protection. It leads to thick black smoke when it comes in contact with fire, which is hazardous to health. The outermost layer of the tray is made up of Low Smoke Zero Halogen (LSZH), which prevents the cable from catching fire. It only produces 20% of the emission caused by conventional cables.


For the last couple of decades, tray cables have come out as a game-changer to better manage and maintain the electrical distribution in any infrastructure. Today, it is changing the way power distribution is implemented and managed in an industry.
