Customized PVC Copper 0.5Mm2 Shielded Instrument Cable

What is a shielded cable?

This guitar cable is also called a shielded cable. This is a cable that has one or more insulated cables surrounded by a common layer that can conduct electrical signals. The shielding layer or insulating layer is made of a conductive polymer layer, an unbraided spiral copper tape winding or a braided copper core wire or other types of metal. The protective cover is usually covered with a jacket.

The role of the shielding layer on the cable is to act as a Faraday cage, which affects the signal from electrical noise. In addition, the shielding layer also reduces the interference of electromagnetic radiation to other devices. The shielding layer also reduces the influence of capacitive coupling noise from other sources on the signal. In order for the shield to be effective, it must be grounded. They are also effective for shielding. This can be achieved through cable glands.

Balanced and unbalanced cables

Have you ever asked yourself what is the difference between a balanced cable and an unbalanced cable? Well, this is the difference. Balanced electrical signals are transmitted through balanced cables. The cable has three wires, namely positive, negative and ground wires. The positive wire and the negative wire carry the same signal. The only difference is that they have opposite polarities. Any interference picked up by the cable along its length will affect both legs or wires. If the destination is balanced, the device receiving the signal will change one signal and restore the polarity of the signals to each other. In this way, ordinary noise can be eliminated alone, so it can be eliminated. This is called common mode rejection. Due to this feature, it is strongly recommended that you use a balanced cable, especially in the case of long-distance cable transmission.

The difference between shielded cable and unshielded cable

Each pair of wires in the shielded guitar cable is wrapped in foil. These wires are also wound again to provide more external protection. On the other hand, each pair of wires in an unshielded cable is twisted together. Wrap the wires again, but do not wrap the wires with any protective material.
