When coming to choose electric cable for installation or connecting network instrument, people usually confused with shielded cable and unshielded cable, how to distinguish and how to choose them has become a problem. This article will explain this problem for you.
First, want to understand these two kinds of electric wire clearly, we need understand what is them and their features.
Shield wire, as its’ name, the main purpose of this cable is shielding, it usually includes on or two layer shielding layer, shielding layer usually is tin foil and weave mesh. Different customer may have different requirements about shielding layer, no matter what material it made, the purpose is to reduce the interference in the signal transmission process and keep the signal transmission secret. So engineers usually use this cable in the occasions that need that require high anti-interference.
According to different purpose, shielded wire has different types. Such as: RVVP shielded signal cable, shielded ethernet cable, shielded twisted pair cable, shielded audio cable, shielded instrument cable, shielded control cable, and shielded telephone communication cable. Both these cables are shielding cable with one or two shielding layers inside the cable.
Compare with shielded wire cable, unshielded wire cable haven’t the shielding layer, it only has conductor, insulation and outer sheath. People usually use it as instrument, power cable, or other occasions not need signal anti-jamming.
According to different purpose and different structure, unshieded multicore cable also has different types, such as: RVV control cable, RVS cable, utp network cable etc. These wire both use in the occasions not need signal transmission protection.
There are some differences between these two wire, you can choose which to use according to their differences.
