With annual average temperatures rising, fires are becoming the norm for much of Australia. Tragic events have cost lives, and building regulations are constantly being expanded to ensure that residential and industrial buildings perform adequately in the case of a fire. Here, particular focus is put towards insulative cladding that extinguishes fires on contact. Many residences and premises however have yet to implement this.  

Another area covered in National Construction Codes and International Standards is the use of cabling. In industrial and commercial settings, different cabling is used for different purposes. Where high levels of heat are generated, specific cables allow for the normal operation of production and other facilities. In fire-prone areas, and emergency signalling systems when a fire does occur, the use of fire rated cable will prevent fire from spreading to other areas, and ensure that evacuation proceeds in an orderly manner.  

Fire rated cables are fitted to smoke alarms, lifts, fire doors, emergency and fire alarms and all areas in industrial and commercial premises where fire is a potential risk. There are different types of cables, each constructed differently and of different materials.  

Heat-Resistant Cables 

Heat-resistant cables are designed to operate normally in high-temperature settings. They are commonly used in such places as steel, ceramic and ironworks, in lighting technology, in ventilation and heating, electric motors, etc. Most are silicone sheathed copper cables used in high voltages. Basic cables running in residential buildings can stand up to 120°C, while the best heat resistant cables can operate up to 250°C without melting.  

Fire Rated Cables 

Fire rated cables differ from heat resistant cables in that they are tested according to specified fire standards and need to either stop the spread of fire or work when there is a fire present. Fire-retardant cables are constructed in such a way that they prevent the spread of flames along the cable length. Fire-resistant cables, go one step further in that they must maintain so-called Circuit Integrity of various electrical wiring, meaning they must operate normally when in direct contact with a flame. Fire-resistant cables can be further divided into 60, 90 and 120 minutes of fire resistance at a set temperature of 750°C or above. Cables pass testing if they are operational after the rated test period. 

How Fire Rated Cables are Constructed 

There are stark differences as to how fire rated cables are constructed. Construction also depends on the application of the cable. Differences in the conductor size and number, the types of insulation, cable screening and outer sheath determine the conditions in which the cables can be used. Fire retardant cables consist of annealed copper conductors insulated with reinforced polyethylene and surrounded by what is known as Low Smoke Zero Halogen (LSZH) thermoplastic sheathing. The sheathing is what stops the propagation of flames to other areas, while also releasing negligent amounts of smoke or toxic materials into the atmosphere (commonly found in cables with PVC sheathing). Fire-resistant cables have a similar construction, but also include Mica glass tape bounding a single core conductor or multiple conductors depending on the type and application of the cable. Higher fire resistance is achieved by a protective layer of metal armouring, either with aluminium, steel or solid copper under the LSZH sheath. Such cables can resist temperatures of over 900°C, over a period of two hours.  

Where Fire Rated Cales are Used 

Typical uses of fire rated cables are in emergency and fire systems. The wiring of fire alarms, voice alarms, emergency lighting circuits and power circuits in such industries as mining, gas and oil exploration, as well as public spaces like hospitals, schools, government offices, sporting venues and high-rise residential blocks, requires the use of fire-rated cable. Other areas where fire rated cables are standard are in communications and manufacturing. Data, coaxial and fibre-optic cables are now fire-rated and come in different build configurations. For manufacturing purposes, power and instrumentation cables are also fire rated. Smelters, kilns and furnaces are prime examples where high voltage fire rated mains and power cables are used in the production of metals, ceramics and glass among other products.  

Fire Rated Cable Standards 

Cables are rated according to different testing parameters and International and Australian Standards. Flame propagation, or the spread of the flame from the initial contact area is prevented by the outer sheathing of thermoplastic. Variants with no or low halogen content reduce the amount of toxic and corrosive gases when in direct contact with fire, so avoid the risk of suffocation due to smoke inhalation. Overall fire resistance is measured at set time frames and temperatures of 750 or 900°C. Different testing methods are used for cables set vertically and those that are set horizontally. 

Final Thoughts 

Heat resistant, fire retardant and fire-resistant cables are built differently and use varying levels of fire protection. Cable manufacturers have extensive lineups of fire-rated cable, each designed for specific applications. Datasheets include a detailed description of materials used, as well as fire resistance, flame propagation, smoke and toxic gas emissions measured according to set standards. Fire-rated cable is sold through cable and industrial retailers and wholesalers.

When the optic cable is tapped, it is easy to monitor because the fibre cable leaks light, causing the whole system to fail. Fibre networks enable you to put your hardware and all electronics in one central location, instead of having a wiring closets throughout the whole building.

Reliability And Immunity – Fibre optic products provide very reliable data transmission. It is totally immune to different environmental factors that usually affect the copper wires. Because the core is made of glass, there is no electric current. It is immune to radio frequency and electrometric interference, impedance problems, crosstalk and other network problems. Also, the fire cables are less susceptible to temperature and can be submerged in water.

Design – Optic fibre products are thin, durable and lightweight. Plus, the optic fibre cables have pulling specifications that are up to 10 times greater when compared with the copper wires. Because they are small in size, they are easier to handle and also require less space. Although fibre is more difficult to terminate, the recent advancements are making the termination process easier.

Migration – The lower costs and proliferation of media conversion are making the copper to optic fibre migration much easier. The conversion offers seamless links and allows usage of existing hardware. Fibre cables can also be integrated into networks in planned upgrades.

Cost – The price of the fibre optic products, cables, other components and hardware is constantly dropping down. The installation costs are higher when compared with the installation of cooper wires, but is definitely a worthy investment that can save you a lot in the long run. Fibre cables generally require less maintenance, have less downtime and require less networking hardware.

With increased speeds online, companies of all sizes are looking for ways to make sure their networks are operating at peak effectiveness. In other words, to ensure data transfer at high speed, companies are using Cat6 cables s which are slightly more high-tech than the cat5, and have more benefits. Cat6 cables work best when all computers and related accessories in a network work at gigabit speed. Also, they are ideal for building a new network. The Cat6 cables were first introduced in the early 2000s, and are now widely replacing the cat5 cables. Here are few reasons why buy cat6 cable.

Speed – The structure of the Cat6 cables is very similar to the Cat5 and Cat5e cables – it consists of eight wires curled together forming four pairs. Unlike Cat5 cables, the Cat6 cables have separators that prevent each wire pair from getting into contact with each other. This helps create faster bandwidth which is why Cat6 cables are capable of speeds up to 1Gigabit unlike the Cat5 cables.

Scalability – With Cat6 cables your network installation will be scalable as your business grows. To take full advantage of the Cat6 cables, all your network devices must to be upgraded. Of course, you can slowly upgrade your network, but buy cat6 cable today.

Everyone prefers the wireless technology when it comes to network connections. From 3G, 4G to Wi-Fi hotspots at every coffee shop, airports and restaurants, people search for ways to free themselves from cables while using the Internet for chatting with friends, e-mail applications or browsing through the Web. Although the wireless technology is certainly more convenient, the Internet users are still exposed to some disadvantages when compared to the network connections that use Ethernet cable. The Ethernet cable for your Internet or network connection can be less convenient, but there are certainly some benefits that you need to consider before relying entirely on a wireless connection.

Low Cost – Although many new tablets and laptop models include adapters for wireless network, some old models and desktop computers don’t include such adapters. So, if you want to add a wireless network to your old desktop or a laptop computer, you have to buy a special wireless adapter which can be quite expensive. Compared to this adapter, the Ethernet cable is a cheap solution. You can buy a 300 meters roll of Ethernet cable for about the same price as a wireless adapter. With this cable you can wire all computers in your home in one quick and efficient way.

Less Downtime – If you use using your laptop or desktop computer near the wireless router, the network connection will be at full strength. But, if you use the connection in other rooms away from the wireless router, then you may experience dropped or cut-out signal problems. This is another reason why you should rely on the Ethernet network cabling. The connections with Ethernet cable are reliable and don’t suffer from dropped signals, unless someone cuts the cable. Also, the wired users experience significantly less downtime due to network connection issues than people who use wireless connection.

Security – The security is another major factor to consider when choosing the type of network cabling connection in your home. Wireless network connection gives you option to use passwords for increased protection. An experienced and knowledgeable hacker can infiltrate in your wireless network with no problems. However, hacking an Ethernet cable connection would be much harder, because a cable access to the router would be required. Therefore, the Ethernet cable connection can provide you with increased security and protection.

Nowadays, most business networks use switches to connect printers, computers and servers within an office building. Switches serve as controllers, which enable network devices to communicate with each other efficiently. But one of the most important thing we need to know about switches is that they save money and increase the productivity of employees through sharing information and resource allocation.

A network switch resembles a router and although both devices are used for similar applications, each has own functions within a network.

A network switch is a device which has fixed number of network ports that can connect several network devices to the home local area network (LAN). The networking switches are primarily used for sharing internet connection between several computers, bur a network switch is also being used for sharing network resource like NAS box or printer in order to be accessed by all network users.

Nowadays, the network switches have speed of 100 Mbps/1000 Mbps per port, which is more than enough for any network application. All network devices are connected to the network switch with twisted copper pair cables.

All laptops, computers, printers and other devices that are connected to the network switch need network adapter or network interface card (NIC) in order to connect to the network. Usually, most of them have built-in NIC cards. The network switch and every device connected to it, require an IP address provided by a router. To access one, first terminate the Internet connection to a modem that is in-turn connected to the router. Toady, the wireless routers usually come with a built-in modem, so a modem plus router is equal to one device. However, cable modem may require a separate router in case you want to share your internet connection with several users. Additionally, wireless routers include several network switch ports for connecting other devices to the network. You can connect new network switches to the wireless router if you want to extend the wired network in order to accommodate more devices or you can connect other devices in a wireless mode.

Therefore, a network switch is really useful and helpful device that can connect several other devices to the home network. Every device that is connected to the switch is automatically connected to everything else that is connected to the switch. The network switches enable you to add more devices to the network any time you want. Therefore, if you’re thinking of connecting multiple devices to your home network connection, you will need to buy network switch. Network switches can be found in every well-equipped computer store or you can buy network switch from a reliable online store.
