Shielded Wires

Shielded cables are quite famous for obvious reasons. If you are looking to purchase efficient cables for your Ethernet, power and computer connections, it is highly recommendable to choose shielded options. There are several kinds of shielded cables available on the market. However, each type suits a specific requirement so you should scrutinize your needs. Most cables used in office connections, computers, power supply, and the internet include a shield. However, not all applications require shielding. It all depends on what you want to achieve. Here are ten reasons why you should choose the shielded cables.

1. Reduce EMI (electromagnetic interference)

EMI is perhaps the main reason why cables come with shielding. According to experts, shielded cables offer better protection against both electromagnetic interference and radio frequency interference from other wires. Unshielded cables tend to suffer more EMI, which causes resistance and hinders data transmission as different signals act on the cable. Shielding offers a protective layer that prevents surrounding electromagnetic fields from causing interference.

2. Protect the cable

Shielded wire provides more protection from day to day wear and tear, corrosive elements and physical abrasion. Unlike naked cables, the shield contains the first layer of protection. If someone steps on the cable or there is a spillage, the guard will protect the wires underneath. Computer and power cables come with a protective shield or coating that can withstand various elements. They are also straightforward to clean and protect the internal wires from dirt, rodents, insects, heat, liquid and accidental tension.

3. Prevent internal cross-talk

Most cables have pairs inside the outer protective shield. Power cables, for instance, have the live, healthy and earth wires. Each wire has its protective shield beside the outer cover that encloses the cord. This shielding prevents the two wires from coming into contact and causing short circuits. In data cables, they prevent internal crosstalk and interference, ensuring each wire effectively does its functions. Cross talk is more like EMI, but the intervention stems from within rather than external sources.

4. Safeguard your data

Cable shielding prevents the boosting of electromagnetic radar. It is particularly crucial for Ethernet cables. Without the shield, your cables will produce higher electromagnetic detectors allowing other people within a reachable distance to access your data. Using shielded cables will keep your data within a safe range and prevent external interference.

5. Protect other devices

Protect other devices

Electromagnetic interference and radar from other fields can affect the performance of your cables. In the same way, your cables produce electromagnetic fields and radar that can cause interference in other fields. This is common when using speakers, radio and phones, among others. The noise and interference can damage your speakers and change the way data or current flows in other cables. Shielding simply protects other devices.

6. Protect cable users

According to studies, safety is one of the major concerns when dealing with cabled connections, especially if you have implantable cardiac devices that can suffer EMI. Although you can safely hide some cables behind walls, this is not possible for all wires. If you have computers and networks in your home or office, some wires will remain exposed. You might also come into contact with wires from time to time. These cables can carry high voltage and have the potential to harm users. It is like touching a live wire that has current flowing inside it. Shielding may comprise a conductive coating as well as an insulating layer to keep users safe.

7. Availability

If you are in the market for computer cables, coaxial cables, and power cables, most offers that you will come across have shielding. They are the most effective options for data and electric transmissions. Since your cables will get old and need replacement, it is only logical that you invest in readily available alternatives.

8. Affordable

Besides being readily available, shielded cables are quite affordable. They make up the bulk of new cable connections so you will save a lot especially if you have extensive cable requirements. It is essential to note the difference between affordable and cheap. Affordable cables are not necessarily cheap. Your priority should be to find high-quality cables.

9. Easy to handle

Easy to handle

Shielded cables provide better transmissions, more protection from external interference and safety. They are straightforward to use and handle. You can connect, split, replace and tape wires together without causing significant compromise on the cable's efficiency.

10. Multipurpose

Shielded cables form the bulk of computer connections. They are also versatile meaning you can use them to accomplish different kinds of relationships. If one of your cables breaks, you have the option to purchase a new one or find a way to rejoin it. You can also substitute different wires if they have the same functions. However, you should make sure the cable meets the required specifications.


There are several other minor reasons why you should consider shielded wires at your place. Wire shields offer safety, security, and longevity in addition to facilitating efficient communication between devices. Nevertheless, not all shielded options are valid. You still need to compare and contrast existing offers before making the final decision. Make sure you purchase cables that meet the specifications of the connection you want to accomplish. You should also buy from credible, reputable retailers and manufacturers that can guarantee high-quality shielded wires.
