What is Coaxial Cable?

Have you ever wondered what makes your TV or internet work so well? The answer lies in a versatile solution for signal transmission called coaxial wire. It has been a staple in the electrical industry to send data, audio, and video. If you’re thinking about what exactly a coaxial cable is, and why it’s a widely used electrical wiring system, continue reading to find out.

How Does Coaxial Cable Work?

Unlike fibre optic cables that employ light, coaxial cable uses electricity to send information. Commonly known as ‘coax’, it’s a type of wire designed to carry electrical signals efficiently over long distances. Its name derives from the four parts being built around the same centre. They are:

  • Centre Conductor: Usually made of copper or copper coated steel CCS, it’s the heart of the cable where the main signal travels. TV RF radio frequency signals resonate around the outside of the copper.

  • Dielectric Insulator: Around the centre wire is a layer of polyethylene or foam. This insulation keeps the signal strong while also preventing it from escaping.

  • Metallic Shield: Next comes a metal layer braided acting as a shield either in copper or aluminium foil. Copper is best for CCTV while aluminium is best for TV. The shield acts like a barrier, this shield helps keep outside electrical noise from interfering with the signal inside. Furthermore, it prevents the signal from disturbing other nearby cables.

  • Outer Jacket: The final layer is a tough PVC jacket that performs several functions. Firstly, it protects all the inner parts from damage. Plus, it helps the cable resist water, heat, and cold. In all Skandia RG6 cables we use UV resistant PVC to protect the cable from the sun and outside exposure as well as flame retardant to ensure they are is fire resistant.

Coaxial Cable in Internet Connectivity

One of the primary applications of coax is to bring the internet to our homes and offices. They are excellent at carrying large amounts of data over long distances without affecting quality. When connected to routers and modems, you can expect to get high-speed connectivity. This is the reason many service providers use coaxial internet cables for their broadband connections.

Can We Use Coaxial Cables Outdoors?

You can use all Skandia RG6 coaxial cables outdoors, it’s important to choose the right type to get uninterrupted signals our coaxial cables are UV and flame resistant . Skandia cables are outdoor-rated wires designed to withstand the environmental elements. These robust cables have a strong outer layer, often made of materials like polyethylene or PVC. This extra protection helps them stand up to sunlight, rain, and temperature changes.

Some Skandia outdoor coaxial cables even have special features like gel filled to keep water out. No matter which type you use outside, it’s vital to seal the connections properly during installation. This step helps the cable last longer and keeps your signal strong as well as clear.

Applications of Coaxial Cable

What is coaxial wire’s best application, you ask? Honestly, they are used in numerous ways in the electrical industry, like in broadband service. Apart from that, you can also find them in the following applications:

  • Television: Cable TV, antenna systems, modems, satellite receivers, and other devices rely on coax for audio and video signal transmission.

  • Radio Communications: This electrical wire is used as a transmission line for radio frequency signals.

  • Audio Equipment: You will find many audio coaxial cables out here as they have excellent noise rejection capability.

  • Security Systems: Coax is a go-to choice for closed-circuit television (CCTV) setups that link cameras to recording devices. Companies find them reliable for surveillance as they allow high-quality video feed transmission over large distances.

  • Industrial Settings: Many businesses depend heavily on coaxial electrical wires. For example, this system acts as a connector between equipment and sensors so that employees can monitor systems.

  • Medical Field: Medical imaging demands the transmission of uninterrupted signals. This is where coaxial cable comes in, which connects monitors to the imaging equipment and devices.

Varieties of Coaxial Cable

There are many different types of coaxial wire are available on the market and many different types of brands this market is often unregulated and it is important to buy from an established company like Skandia, we have nearly 40 years’ experience in the coaxial market. Our dual shield RG6 coaxial cable is arguable the best in the Australia market and out preforms many quad shield brands. RG6 is the most commonly used cable in cable pay tv digital television and satellite TV installations. It stands out for many reasons, including:

  • Has a larger conductor and improved shielding compared to its predecessors

  • Less signal attenuation over long distances

  • Higher bandwidth capacity

  • Cleaner signal transmission in environments with potential electrical noise

  • Suitable for various applications

  • Cost-effective

Also, when selecting the right coaxial line for your project, consider key factors like:

  • Frequency range compatibility

  • Impedance matching (typically 50 or 75 ohms)

  • Appropriate cable length

  • Adequate shielding for interference protection

  • Suitable connector type

At SKANDIA, we understand the importance of selecting the appropriate cable for specific projects we have nearly 40 years’ experience in the Australian market. We were there when Pay TV started and assisted with the Digital TV switch over. That’s why, Skandia offer a range of high-quality coaxial wire suitable for diverse applications. Whether you’re undertaking a residential or a large-scale commercial project, we have the products to meet your needs.
