What is the distinguishing feature of Type MV cable?

Type MV cable is characterized by its metal sheathing, which serves multiple purposes in electrical installations. This metal sheathing provides enhanced mechanical protection against physical damage, as well as protection against moisture and other environmental factors that could compromise the integrity of the cable. The presence of metal sheathing also helps to shield the cable from electromagnetic interference, which is particularly beneficial in industrial settings where equipment may produce significant electrical noise.

While other choices reference attributes like voltage ratings, flexibility, and installation environments, these are not the defining features of Type MV cable. It is specifically designed to handle medium voltage applications and is often suitable for both overhead and underground installations, making it versatile beyond just underground use. The focus on metal sheathing distinguishes Type MV not only by its construction but also by its ability to meet the rigorous demands of electrical systems in commercial and industrial environments.
