1 Style Cable Tray Typical Installations Chalfant Cable Trays

2 Tray When metal ladder cable trays came of age, they were used to support the new armored shielded power cables that were permitted outside the conduit environment. Utilities and industrial companies initiated the use of expanded metal and solid trough-styled trays for supporting power and control cable. Cable trays quickly proved their worth as a safe, dependable and cost-effective solution to routing and supporting cables. Installed cost savings of over 0% on project after project drove the market for metal cable trays to over 0 million dollars. Cable Tray is NOT WIEWY and is viewed as a support for cables. This provides the designer and user many benefits. Full free air rating of cables, results in smaller conductors vs. conduit Greater fill volume allowed, results in less space Used in all locations except elevator shafts (the only prohibition on cable tray use) Used as an equipment grounding conductor (classified by UL) Less stress on cables during installation and operation Increased safety, no moisture condensation problems nor transmission of corrosive or explosive gases, as with conduit Simplified maintenance with the flexibility of adding or changing circuits Simplified engineering and construction. dd, change, modify more easily Used with other wiring methods Longer support spans up to (Chalfant s standard systems to 0 ).

4 Selecting & Sizing Cable Tray Systems The Cable to be Supported Determines the Type of Tray type cable can support heavy power cables or small circuit size communication cables for control data and phone cables or a mix. ung Spacing: Single conductor over /0 and MC cables should be used with or rung spacing. Smaller diameter cables require or rung spacing. Trough, solid or ventilated type tray offer protection and better support for small, lightweight instrument or data cables. ints: arrier strips can be used to separate voltages or power and control cables to avoid the cost of adding a second or separate tray for each. Covers are not required by the NEC Code and add to the cost of the job. owever, they should be considered for protection of personnel and any debris or other material that could fall into the tray. Select which Metal and/or Material Finish Your pplication Will equire The job site and its environment will determine which metal and/or material finish you use. eview where the tray is being used. re there unusual corrosive conditions (like those found in some chemical and paper processing plants)? See page - for a list of various tray materials and finishes available. ints: luminum - Most conditions are satisfied by aluminum tray which is also the most popular type. It s less expensive and an easier system to install. Unlike galvanized steel, its finish is always smooth. Longer span tray systems are also available in aluminum. luminum tray is ideal for seacoast, offshore and most petrochemical and pulp mill applications. Galvanized Steel (DGF STM Class ) - This hot dipped galvanized steel is used in outdoor, chlorine, acid or caustic areas. Steel trays can have a rough finish (VE -..) which could cause cable damage. It also adds two to three weeks to delivery time. Trays with mill galvanize steel finish STM are the least expensive and only recommended for indoor applications. Stainless Steel trays are used in special highly corrosive environments and compare favorably with fiberglass type ladder tray. Determine Type of Support int: eview the various support methods and options shown in the accessories section of this catalog on pages -0, -, -, and -. The distance between each support is the support span. You can support your cable tray system: from walls or vertical columns with shelf or cantilevered brackets with trapeze or single supports using threaded rods hung directly from building steel on or under pipe racks, trestles or bridges In utility trenches, tunnels or directly on roofs off the ground, using pedestal supports. int: You can save money by using a heavier duty tray that results in longer spans and reduces the number of costly supports and installation time. heavier duty tray will also provide a deeper loading depth and a stronger, less deflective, long-span support. Determine Cable Load to be Supported eview the number and type of cable from the job specifications and requirements. Cable fill in a tray is calculated by using data and criteria specified in NEC. To determine total cable weight, add all cables on a lb/ft basis. ints: Data, telephone and instrument cable should be calculated to fill tray to 0% of the tray cross section fill area (0% for solid bottom tray). In reality, because of voids, overlapping and the circular shape of the cable, a 0% fill will normally completely fill the cable tray. MC cable /0 or larger, rated 000 Volts or less, can only be installed in one layer (sum of cable diameters equals tray width). Single conductor 000 Volts or less, larger than 000 KCM can only be installed in one layer (sum of cable diameters equals tray width). Other power cables and combinations of sizes are calculated on the sum of cable areas versus allowable fill, see table NEC. to determine tray width. NEC details cable types, voltages, ampacity, etc. Other Loads to be Calculated: Snow: dd. lbs/square feet for 0-inch deep wet snow. (Example: For a -inch tray width - X. =. lbs/sq ft.) Ice: dd. lbs/square feet. Concentrated Load: dd load effect (W e ) for concentrated load effect from splice boxes, heavy cable drop outs and conduit terminations supported off tray. W e = times the concentrated load divided by the support span. (Example: For a 00 lbs. concentrated load at a center span of 0 ft, W e = X 00/0 = 0 lbs. per ft added load. ) Once you have determined your worst case load, add it to your other cable load calculations. You now have the maximum load the tray must support. ints: It is not necessary to specify tray rung type when using Chalfant. Chalfant rung designs can handle a minimum of 0 lbs. at any width. Chalfant uses rung styles to assure this standard is maintained. For example, Strut ung # is rated at lbs. at wide. eview You have now determined:. Tray type. Tray material and/or finish. Support type & span between supports. Total load in lbs/ft Select Tray System (For aluminum, use Selection Chart on pages -,-, - and -.) (For steel, use Selection Chart on pages - and -.) eview Selection chart and the various notes in general. Start at the top of (your) support span column and work down to locate a tray system to handle your total load. Example: You have determined you need a ladder tray (aluminum) at a 0 ft span and 00 lbs/ft load. Using Selection Chart on pages - and -, go down 0 ft span column until you reach Tray System. This is the best tray for your application. Note: If you use a shorter span, you must choose between a, or load depth. Order your tray using the Part No. Code on page -. Contact your Chalfant Sales epresentative or the factory if you need help sizing and selecting your tray. Chalfant Cable Trays -

Not recommended for use in chlorine, caustic or high acid environments. ungs ungs are box construction 0. high with, and - bearing surface. ll trays (except ) and rungs are designed to handle cable loads plus 00 lbs. of concentrated load for any tray width. For example, strut rung # can handle lbs. at a. Low profile rungs are available in to provide a load depth. Galvanized and Stainless Steel Tray ot Dip Mill galvanized tray STM G0 coating is the least expensive tray and is recommended for indoor applications only. ot dipped galvanized after fabrication STM is recommended for outdoor use. It is more expensive than aluminum and requires great care in galvanizing to prevent icicles, bare patches, warpage and rough surfaces. Stainless steel tray is available in 0L and L and is often the least expensive solution for use in highly corrosive atmospheres. It also competes favorably against fiberglass systems. Steel ungs ungs are high with bearing, gauge. special gas relief hole for DGF is punched on both ends to assure complete galvanizing. Chalfant Cable Trays -
