Our Product Knock-out series is a match-up between two similar products. In boxing terms, think same weight class, same caliber, and same level of experience and amount of exposure. The purpose of these posts are for you to see a side-by-side view of two similar products, and to be able to understand which one will be crowned champ for your specific purposes. Take your seats and prepare for battle, because the gloves are coming out.
Tray cable and teck cable are power cables both used for direct burial purposes. Although teck cable is rated to Canadian standards, (CSA) both teck and tray cables have many overlapping similarities. Let’s begin by taking a closer look at each of these cables!
What is Tray Cable?
Tray cables are multi-conductor and multi-paired cables generally used in signal and energy transmission with minimum interference, as well as for installation in trays, wireways, troughs, ducts, conduits, and channels. There are several different types of tray cable, including Type TC Tray Cable, Power Limited Tray Cable (Type PLTC), Instrument Tray Cable (Type ITC), Wind Turbine Tray Cable (Type WTTC), and Exposed Run Tray Cable (TC-ER). Depending on your specific application’s needs, one tray cable rating may work better than another.
What is Teck Cable?
Teck cable, known as TECK90 Cable, is CSA approved cable rated 600 to 5kV. Teck cable is found in single and multiple conductor constructions with an inner jacket, aluminum or steel interlocked armor, with a PVC jacket overall. Often dual rated NEC type MC cable, TECK90 is designed for use in hazardous applications (HL Rated), often mining; petroleum; chemical; and pulp and paper industries.

Tray Cable vs Teck Cable
There is a lot of overlap between teck cable and tray cable when it comes to their construction. Both are capable of featuring bare copper conductors, XLPE and EPR insulation, and PVC jackets. However, there are a few significant differences that set these cables apart as well. All teck cable features a bare copper ground wire in the construction which provides a conducting path from the wire to its end point. Teck cable is also always armored. Although there are certain tray cables with grounds and armor, not all types of tray cables offer these features, like teck cable does.
Winner by unanimous vote? Instead, it seems as if the match has ended in a technical decision. In this case it looks like our crowned champ depends on your specific application use.
