According to the NEC, tray cable is a type which is made specifically with at least two insulated conductors and may or may not include bare or covered conductors for grounding. The conductors on these cables are then placed under a nonmetallic jacket. In particular, these cables are intended for installation in applications where they can be supported via a messenger wire, in instrumentation and control, and in power applications, as well as in other contexts like raceways and cable trays. Tray cable varieties from Belden, Southwire, Tappan, General Cable, Nexans, Lake Cable, Superior Essex, and Advanced Digital have been made available through OneStopBuy in a great number of multipair and multiconductor styles.
The versatile nature of tray cables’ construction means that they are able to be used in either dry locations or wet locations, whether indoor or outdoor. They can also be protected with shielding or left unprotected. Whatever the specific application being served, tray cable accommodates an enormous amount of different installations, with capabilities running the gamut from small-scale industrial projects to some of the most heavy-duty ones. Tray cables have remained enormously popular in industries like construction and utilities.
Generally speaking, tray cable insulation is made from one of several types of material. The first is thermoplastic high heat-resistant nylon (THHN), while other options include thermoplastic high heat-resistant nylon water-resistant (THWN), cross-linked polyolefin (XLPO), ethylene propylene rubber (EPR), rubber that is resistant to flame (FREP/FR-EPR), and cross-linked polyethylene (XLPE/XHHW). When it comes to jacket materials, the main choices include polyvinyl chloride (PVC), chlorinated polyethylene (CPE), and low smoke zero halogen (LSZH).
Two Main Types: XHHW and THHN
The first of the two categories of these cables is cross-linked polyethylene high heat-resistant water-resistant cable, which is abbreviated as XHHW. XHHW is made for endurance of high-heat situations and has ratings that demonstrates its ability to operate in overcurrents and remain guarded against short circuiting and fires. In addition, it is resistant to sunlight and appropriate for direct burial, having been constructed with a strong, thermoset insulation.
A second and more traditional variety of tray cable is thermoplastic, high-heat nylon cable (THHN). This type is not as tough as XHHW because of its having thermoplastic rather than PVC insulation material. As a result, it may often be more susceptible to damage by exceptional levels of heat, moisture, or pests like ants and rodents. Because this line of products from manufacturers such as Nexans, Belden, Advanced Digital, General Cable, Southwire, Lake Cable, Tappan, and Superior Essex doesn’t have the same premium features of XHHW cables, THHN cables are usually lower in cost.
