Both tray types are available in multiple resin systems, and offered as a complete system including fittings, supports, and accessories. 3) These brackets are entirely insulated, which terminated the electric-erosion, and reduces damages caused by eddy current. 4) The brackets are water resistant which can be used for long-term in moist and watery conditions. 8)Not like steel brackets, these brackets are entirely insulated, so no earthing system is needed.
[2] A ventilated tray has openings in the bottom of the tray, allowing some air circulation around the cables, water drainage, and allowing some dust to fall through the tray. Small cables may exit the tray through the ventilation openings, which may be either slots or holes punched in the bottom. A ladder tray has the cables supported by a traverse bar, similarly to the rungs of a ladder, at regular intervals on the order of 4 to 12 inches (100 to 300 mm). Ladder and ventilated trays may have solid covers to protect cables from falling objects, dust, and water. Tray covers for use outdoors or in dusty locations may have a peaked shape to shed debris including dust, ice or snow. Lighter cable trays are more appropriate in situations where a great number of small cables are used, such as for telephone or computer network cables. These trays may be made of wire mesh, called "cable basket", [2] or be designed in the form of a single central spine (rail) with ribs to support the cable on either side.
In the electrical wiring of buildings, a cable tray system is used to support insulated electrical cables used for power distribution, control, and communication. Cable trays are used as an alternative to open wiring or electrical conduit systems, and are commonly used for cable management in commercial and industrial construction. They are especially useful in situations where changes to a wiring system are anticipated, since new cables can be installed by laying them in the tray, instead of pulling them through a pipe. According to the National Electrical Code standard of the United States, a cable tray is a unit or assembly of units or sections and associated fittings forming a rigid structural system used to securely fasten or support cables and raceways. [1] Types [ edit] Several types of tray are used in different applications. A solid-bottom tray provides the maximum protection to cables, but requires cutting the tray or using fittings to enter or exit cables. A deep, solid enclosure for cables is called a cable channel or cable trough.
Recommended Cable Tray Manufacturers: 2) Trapeze Beam Maximum Allowable Uniform Vertical Load (lbs) Notes: 1. Values in this table apply only to Unistrut brand products. Unistrut channels are stamped with the name "UNISTRUT". 2. Values in this table are valid with all solid, T, WT and HS pierced channels of the above channel profiles. 3. * Load is limited by spot weld shear. Weld shear and tension are accounted for in the above listed capacities. 4. Refer to OPM Page 4b. 0 for the detailed calculation procedure. 3) Brace Member Maximum Horizontal F P Force (lbs) [ASD] at 45° from Horizontal Notes: 1. These brace members are valid for angles from 0° to 60° from horizontal. Refer to product or OPM pages for capacities. 4) Brace Fitting F P Load Capacity (lbs) Notes: Use with P3860 base. Use with LS 100 base. Use with LS 200 base. All angles above are from horizontal.

Fabricated in light duty aluminum, Cope's Rapid Tray conforms to NEMA specifications for 8A and 12A tray systems. Cope Cope (Harvey, IL) has introduced Rapid Splice, a newly designed splice plate for the company's Rapid Tray system that adds more efficiency to the installation and management of cable tray systems. The new design eliminates 67 to 75 percent of cable tray hardware, reckons Cope, saving cabling contractors and installers time and labor costs, while reducing support requirements, and enhancing the structural integrity and strength of the system. Per Cope, "Rapid Splice can be used in a wide range of cable tray configurations. It's designed to fit snugly to the C-Beam profile of the cable tray ladder to create superior lateral strength and rigidity across the ladder sections. Due to this added strength, only two bolts are needed to secure Rapid Splice in place, saving time and labor for the installation crew. " Rapid Tray uses Cope's proprietary cold swaging process, which the company says provides better grounding properties and higher pullout strength than welded rungs.
