Have you ever wondered about what it is that connects computers and networks to each other? Network cable together with the hardware (network switches, hubs, demarcation equipment) is responsible to allow computers connect and transfer data across intranets (internal network) and the internet. Today, network cabling is utilized for a wide variety of reasons other than computer networking. It can carry video for security camera systems, as in addition to video for cables for TV as well as AV (Audio/Visual) devices. Network cabling also serves to control cables in Building Maintenance Systems and Access Control Systems. There are various kinds of cables that are used for this purpose, including unshielded twisted pair, shielded pair or fiber optic as well as coaxial. In some cases, only one type of cable is employed in networks, but in other circumstances various types are used. Wireless networks are becoming more and more popular , but keep in mind that there is still a need for network cabling to connect wireless systems. Two things remain to make network cabling better than a wireless network one of which is that it is more safe and reliable.

This is the type of cable that is utilized in many Ethernet networks. There are four sets of wires in the cable. There is a thick , plastic separator that keeps each pair separated throughout the line of cable. This means that each pair are made to be twisted, ensuring in no way to interfere with devices that are on that same network. The wires are also twisted at different intervals so that they will not cause interference between the pairs. When you have a lot of Electromagnetic Interference (EMI), such as a mechanical space one could opt to go with a shielded pair which comes with an outer shielding , which offers extra protection from EMI. Category 5e, 6A, and 7 are common choices today. Twisted-pair cable is limited to 295' in a horizontal run. Twisted pair cable is used for a myriad of uses. The standard station cabling used for computers as well as VOIP phones Wireless access points, network cameras, access control and maintenance of buildings are just several. It is among the most reliable kinds of cables, and when it is utilized, network breakdowns are less frequent than when other cables are used.

Fiber optic cable is typically utilized as a backup cable, even though it is becoming used more and more frequently as station cable (think"FIOS). When I say backbone cable, that it links Telecommunication Rooms within a space to each other. Fiber optic cables boast huge capacity to transmit broadband which allows it to carry huge amounts of information at extremely fast speeds. Fiber optic cables can travel over huge distances(hundreds of meters) when compared to copper cables. Because these cables must endure such a high workload and because the data is transferred over long distances there are numerous layers of protective coatings that are present on Fiber optic cables. Fiber cables transmit light as instead of electrical current. Fiber optic cables require less power than high-speed copper does. In addition, fiber optic cable offers an excellent choice for high-speed reliable communications.

Cable paths need to steer away from electrical light fixtures or additional sources that could cause EMI (Electro Magnetic Interference). Cable paths should be located in easily accessible portions of the ceiling to allow for future cable runs and for ease of maintenance. All pathways should be run above hallways or corridors and cables should enter rooms in sweeps of 90 degrees. Install a firestop protection sleeve or putty to all openings in an fire wall. Be aware when pulling cables to ensure not to be bent beyond their bend radius. This can result in a failure when testing. Don't tie cables to hanging ceiling slats, or even sprinkler pipes. They must be secured at most every 5' on horizontal runs and more frequently for vertical runs. J-hooks should be attached onto the concrete deck that is above. Use velcro wraps on every 5' or so , when you've finished running cable , to give your cable bundles a stunning look.

Add a subpanel with a few extra slots ($250), or, if you’re planning major home improvements, replace the existing panel with a larger model ($500. Electrical cables are frequently blamed by the media and fire authorities as to the cause of fires, however, it is often not the failure of the cable which starts a fire but the misuse of the cable by frayed or damaged insulation, overloading due to incorrect or insufficient circuit protection, short circuit or. Otherwise, modern bx and romex have positive, neutral, and ground wires.

To be exact, 14 cables and 4 junction boxes.

I've heard that when the armor is used as the ground (no internal grounding strip) this can cause the armor to get hot and is a potential fire hazard. Fire spread & flame retardance.

My Family Lives In A 1923 Colonial.

The actual name for it is “armored cable” or ac, but many people call it by its original trade name “greenfield” or just bx. If you are interested in bx cable and electrical fire,please feel free to give your inquiry in the form or the email below.we will reply you in 24 hours. In bx, the ground wire has a plastic protective sheathing, whereas romex, the copper wire, is bare.

Commonly Known As Swa Cable, The Steel Wire Armoured Cable Is A Power And Auxiliary Control Cable, Designed For Use In Mains Supply Electricity.

Fire spread & flame retardance. It has become a generic term for all armored cable. The main difference between bx and romex is the outer protective covering.

Bx Is The Older Term For This Type Of Cable.

It is acceptable to the latest version of the national electrical code (201. (f) incorporated in a cable having a metal armour or sheath; Bx wire serves as its conduit, whereas romex requires a conduit if used outside of finished walls.

Can You Use Bx Cable In A House?

Modern bx wiring, properly installed, is safe. I've heard that when the armor is used as the ground (no internal grounding strip) this can cause the armor to get hot and is a potential fire hazard. But safety of an existing bx system does depend on its age, type and how it was installed.
