Cable Trays are usually usedby constructions and developing industries, for their many different projects.Cable trays are used to collect and distribute cables. Steel, plastic,aluminum, fibreglasses are mostly used for making cable trays. Cable trays arethe back bones of constructions and developing industries.Types of Cable TraysTypes of cable trays are tobe follow-1) Ladder Cable Tray:Ladder cable trays areusually used for China Collapsible Drink Bottle applications to long support spans normally ladder cable traysare 12 to 30 feet long.2) Perforated Type Cable Tray:Theperforated type cable trays are made of Mild Steel IS 1079, Pre-Galvanized Sheet, Stainless Steel &Aluminum and some important information about perforated cable trayAs follow-Width - 50 mm to 1200 mmHeight - 10 mm to 100 mmThickness - 1.2 mm to 3mm Length - 2444 mm / 2500mm / 3000 mm3) .
Solid Bottom Cable Tray:Solid Bottom Cable Trays aremostly used for minimal heat generating electrical or telecommunicationapplications with short to intermediate support spans, solid bottom cable traysare maximum 5 to 12 feet long.4) Channel Cable Tray:Channel cable tray isconsisting of one piece, channel cable tray used by all different industries tocarry their smaller equipments, data communication and it also include computerhardware equipments, telephone and control and fiber optic cable.5) Single Rail Cable Tray:Single rail cable tray isvery much important for saving time and money for those lighter-duty cablesupport projects that do not require a traditional dual side rail cable tray.Generally single rail cabletrays width are 6 to 24 inches, depth are 3 to 6 inches and lengths are 10 to12 feet. Single rail cable trays are generally used for low voltage and powercable installations because where cable gets maximum freedom, side fill andspeed to all install are factors.6) Trough Cable Tray:Trough Cable Trays are mostlyused for moderate heat generating with short time to intermediate supportspans, and it is normally 5 to 12 feet long.
7) Wire Mesh Cable Tray:Wire Mesh Cable Trays aregenerally used for telecommunication and fiber optic application, installed onshort support spans.Advantages of using Cable Trays for wiring systemsGenerally cost isa major consideration in the selection of a wiring system. This articleprovides information as to where cable tray wiring system cost savings willoccur; however, it is not the intent of this article to state that the selectionof a wiring system should be based only on cost.Early in the lifeof a project, the costs and the features of the applicable wiring methodsshould be evaluated to provide decision information for the selection of thebest possible wiring method or methods for the project. The evaluations shouldinclude items that relate to cost, dependability, future changes, maintenance,safety, and space savings.
