The NEC (National Electric Code) tray cable definition:

“A factory assembly of two or more insulated conductors, with or without associated bare or covered grounding conductors under a nonmetallic sheath, for installation in cable trays, in raceways, or where supported by a messenger wire.”

Tray cables are generally installed in trays, wire-ways, troughs, ducts, conduits, and channels. These types of cables are available in flexible constructions for moving applications, as well as in power-limited versions for mass transit systems. For all your tray cable needs, Sycor Technology has the skilled staff and resources to ensure you get the cable you need for the price you want to pay.

Tray Cable's are general purpose cables that can be used in wet or dry locations and come with shielding capabilities, which excel in indoor or outdoor applications. They’re typically used for power distribution and are consistently used to support structures of any size. These cables are a well-known asset for a large majority of construction and utility companies.

Benefits of using a cable tray system:

The cable tray wiring system offers significant advantages over alternative systems like conduit piping. The design of cable trays helps with preventing safety issues, being more cost-efficient, reliable, adaptable and maintainable.

Experience has shown that the tray cabling system can save up to 60% in costs if properly maintained and planned for, compared to traditional conduit systems. Another benefit is the labour costs 50% less, as tray systems are quick and easy to install.

Additional benefits:

Requires less to reconfigure system when change is required.
Fewer environmental issues from power loss.
Less costly maintenance and engineering.
Less downtime for data management systems.

Tray Cable system Glossary:

Tray Cable Connector An electrical piece of equipment that's used to connect 2 or more tray cables together. Popular connector types consist of ‘adjustable’, ‘reducer’, ‘expansion’ and ‘rigid’.
Tray Cable Support A reliable piece of equipment used for supporting fittings and tray systems. Popular types of support are: Trapeze, Individual and suspension and cantilever bracket.  
Channel Cable Tray A channel cable tray is a metal tray consisting of a solid or ventilated bottom section that doesn’t exceed 6 inches in width.
Tray Reducer A tray fitting used for joining cable tray of various widths together. The 3 main types of reducers are a ‘straight reducer’, ‘left-hand reducer’ and a ‘right-hand reducer’.
Tray System ladder A metal structure made up of 2 longitudinal side rails connected by individual transverse members.
Solid Tray Panel A metal tray with a solid construction and has no opening or longitudinal side rails.
