COURSE SYLLABUS Software’s Included AutoCAD Etap software DiaLux. Electrical cables must be properly supported to relieve mechanical stresses on the conductors, and protected from harsh conditions such as abrasion which might degrade the insulation.Download Free PDF.This is especially important for power wiring to and from devices such as rectifiers and variable-frequency motor drive (VFD) units, which have a tendency to broadcast large amounts of electromagnetic noise.Plastic conduit, of course, provides no electrical grounding or shielding because plastic is a nonconductor of electricity. See the add-on application Block Catalog for AutoCAD 2013 and.Metal conduit naturally forms a continuously-grounded enclosure for conductors which not only provides a measure of protection against electrical shock (all enclosures and devices attached to the conduit become safely grounded through the conduit) but also shields against electrostatic interference. In fact, threaded conduit uses the same thread pitch and diameter standards as NPT (National Pipe Taper) fluid pipe connections.You can download all CAD blocks directly from your AutoCAD, without logins and any limitations. Conduit resembles piping used to convey fluids, except that it is much thinner-walled than fluid pipe and is not rated to withstand internal pressure as pipe is. IGE XAO provides a range of electrical installation CAD software solutions for A traditional and rugged technique for cable routing is conduit, either metal or plastic (PVC). A good practice is to always leave a length of nylon pull string inside each length of conduit, ready to use for pulling a new wire or cable through. Cable “pulls” may be especially challenging if the conduit run contains many bends, and/or is close to capacity in terms of the number and size of conductors it already holds. Two of those conduit runs have been severed following a wiring change, exposing the conductors inside:Installing cable into an electrical conduit is a task referred to as cable pulling, and it is something of an art. Several runs of thin-wall conduit appear in this next photograph. Instead, special connectors are used to join “sticks” of thin-wall conduit together, and to join thin-wall conduit to electrical enclosures. Tayutama game english patchTrays may be made of solid steel wire for light-duty applications such as instrument signal cabling or computer network cabling, or they may be made of steel or aluminum channel for heavy-duty applications such as electrical power wiring. Non-metallic liquid-tight conduit is nothing more than plastic hose, providing physical protection against liquid exposure and abrasion, but no electrical grounding or shielding ability.Another technique for cable routing is the use of cable tray. The metallic kind contains a spiraled metal sheath just underneath the plastic outer coating to provide a continuously-grounded shield much the same way that rigid metal conduit does. Here, we see a motor-operated control valve with two runs of liquid-tight conduit routing conductors to it:Liquid-tight conduit comes in two general varieties: metallic and non-metallic. This provides some stress relief to the conduit in the event the device moves or vibrates, and also allows more freedom in positioning the device with respect to the conduit. Special lubricating “grease” formulated for electrical wiring may be applied to conductors pulled into a conduit, to reduce friction between those new conductors and the conductors already inside the conduit.When connecting electrical conduit to end-point devices, it is common to use flexible liquid tight conduit as a connector between the rigid metal (or plastic) conduit and the final device. These are rectangular sheet-metal tubes containing pre-fabricated copper busbars for the conduction of three-phase AC power. Here, the cable tray has the appearance of an aluminum ladder, with extruded metal rails and rungs providing physical support for the cables:Similar cables trays appear in the next photograph, supporting feeder cables from a stationary transformer and switchgear cabinets:A special form of wiring often seen in industrial facilities for power distribution is busway, also known as bus duct. The cable tray is made of solid steel wire, bent to form a “basket” to support dozens of yellow Ethernet cables:Heavy-duty cable tray appears throughout this next photograph, supporting large-gauge power conductors for electric generators at a gas turbine power plant. A decided advantage of cable trays is ease of cable installation, especially when compared to electrical conduit.While cable tray does provide a continuously-grounded surface for electrical safety the same as metal conduit, cable tray does not naturally provide shielding for the conductors because it does not completely enclose the conductors the way metal conduit does.An example of light-duty cable tray appears here, used to support Ethernet cabling near the ceiling of a room at a college campus. This often necessitates special cable insulation rated for exposure to ultraviolet light, moisture, and other environmental wear factors. Wires pass from the devices to the duct through the slots (gaps) in the sides of the duct, and are enclosed by a removable plastic cover that snaps onto the top of the duct. Wire duct is a plastic channel with slotted sides, designed to be attached to the sub-panel of an enclosure along with all electrical devices inside that enclosure. Two materials useful for neatly routing power, signal, and instrumentation conductors inside an enclosure are wire duct and wire loom. Busways are only used for electrical power distribution not for instrumentation, control, or signaling purposes. In this photograph, we see busway used to distribute power along the ceiling of an MCC room, alongside regular rigid conduit:As useful and neat in appearance as busways are, they are definitely limited in purpose. Busways are used in indoor applications, often in motor control center (MCC) and power distribution center rooms to route electrical power to and from large disconnect switches, fuses, and circuit breakers. ![]() Wire mesh cable tray: Wire mesh cable trays are designed by welding stainless steel wires together forming a basket. Solid-bottom Cable tray: Solid Bottom cable trays are normally used for communication cables to protect from radiofrequency/electromagnetic interference. Perforated type cable trays support then ladder type. Perforated Cable Tray: Perforated type cable trays are manufactured with a perforation at the bottom to provide proper ventilation. Ladder-type cable trays are used for heavy cables as it provides more ventilation then perforated type. We are also providing services for the installation of cable trays in Pakistan. Alfazal Engineering is the only company in Pakistan manufacturing all types of Cable Trays.
