Have you ever thought about what does it take to connect computers and networks to one another? Network cable in conjunction with the associated hardware (network hubs, switches and demarcation equipment) is responsible computer systems being able to connect and transfer data across intranets (internal networks) and over the internet. The network cabling of today is utilized in a variety of ways, not just for computer networking. It can be used to carry video for security camera systems as and video for cable TV and AV (Audio/Visual) Applications. Network cabling is also used as a control cable within Building Maintenance Systems and Access Control Systems. There are several different types of cables that are used for this purpose, such as unshielded twisted pair, shielded twisted pair Fiber optic and coaxial. In certain cases, just one kind of cable is used in a network, where in other situations various kinds are used. Wireless networks are becoming increasingly widespread, but be aware that you will require network cabling to support the wireless system. There are two characteristics that make network cabling superior than a wireless network one of which is that it is more secure and reliable.

This is the type of cable that is utilized to connect various Ethernet networks. There are four wires in the cable. It has a durable plastic separator that keeps each pair separate throughout the line of cable. All pairs of wires are twisted so there will be none interference by other equipment that are on one network. They are also twisted at various intervals, so they won't cause interference between them. In a scenario where there's lots of Electromagnetic Interference (EMI), such as in a mechanical environment there is the option to use a shielded twist and have an outer shielding , which offers additional protection against EMI. Categories 5e, 6, 6A and 7 are the general choices available today. Twisted pair cable can be used up to 295' in a horizontal run. Twisted pair cable is utilized to connect a variety of devices. Standard station cabling for computers and VOIP phones wireless access point, access control, network cameras for building equipment and security systems are but a few. It is among the most reliable types of cables, and when utilized, network malfunctions occur less frequently than those using other cables.

Fiber optic cable can be used for backbone cables, but it is increasingly being used and more frequently as station cable (think of FIOS). By "backbone cable" I mean it connects Telecommunication Rooms within the same space. Fiber optic cables boast huge capacity for broadband, allowing it to transmit large amounts of information at super fast speeds. Cables made of fiber can cover vast distances(hundreds of meters) contrary to copper cable. Because fiber cables must work extremely hard and information can travel such distances there are many layers of protective coating on copper cables. The fiber optic cables transmit light as instead of electrical current. Fiber optic cables require less power than high speed copper does. It is an excellent option for high-speed, reliable communications.

Cable paths must steer away from electrical lighting fixtures or the other potential sources of EMI (Electro Magnetic Interference). Maintain cable paths in a safe zones of the ceiling to allow for future cable runs and for ease of maintenance. Every path should be set over corridors or hallways. cables are introduced into individual rooms by continuous 90-degree turns. Install a firestop sleeve , or putty in all areas of the wall. Be careful when pulling cables so as not to cause them to bend beyond their bend radius. It could result in failure in conducting tests. Do not tie cables onto overhead hangers, sprinkler pipes or ceiling hangers. They should be tied at five feet at a minimum on horizontal runs, and even more often on vertical run. J-hook supports need to be attached to the concrete deck above. Use velcro wraps every 5' to 10' after you've completed running cable to give your cable bundles an attractive finish.

In general, when routing electrical conductors, the cable tray systems are in the path of ground fault currents. Cable tray support systems should be designed, whenever possible, for minimum installed cost. Article 392 covers cable tray systems, including ladder, ventilated trough, ventilated channel, solid bottom, and other similar structures.

The standard length for installing channel cable trays is 10, 12, 20 and 24 feet. It is often used in industrial applications where numerous.

Allow For Adequate Working Space Around The.

Cable trays should be designed and fitted to satisfy current and future requirements. Cable tray systems are used to support cables for power distribution, control and communication in cable management in commercial and industrial application as an alternative to open cabling or conduct system. It is often used in industrial applications where numerous.

The Purpose Of Power Grounding (Article 250) Is To Minimize The Damage From Wiring Or Equipment Ground Faults.

Cable trays and their associated fittings shall be _____ for the intended use. 392.12, cable tray systems shall not be used in hoistways or where subject to sever physical damage.. Cable trays according to osha 1910.399, a cable tray system 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.

In Order To Achieve This Objective, The Engineer Must Bear In Mind That The General Design Rules Established For Aluminum.

Cable tray support systems should be designed, whenever possible, for minimum installed cost. Cable trays provide wiring flexibility, simplicity, and lower installation cost. To be useful, electrical wiring must get from one place to another.

The Distance Between The Cable Tray Support Spacing And Fixing Points Should Be A Maximum Of Three Meters.

The cable tray system selected should be designed around the specific support span chosen for that run. The system should also be designed to support a maximum load of 100kg/m. Cable tray shall be _____ except as permitted by 392.18 d.

In General, Cable Trays Containing Conductors Operated At Over 600 Volts Must Have A Permanent, Legible Warning Notice Carrying The Wording Danger—High Voltage—Keep Away Placed In A Readily Visible Position On All Cable Trays.

The supports are between 1.5 and 3 meters. This cable tray has a ventilated bottom that contains side rails. In general, when routing electrical conductors, the cable tray systems are in the path of ground fault currents.
