An electric cable consists of wires bundled together and covered in a sheathing to carry electricity. Several kinds of electrical cables are currently available in the market. Here, we look at some of these types to gain a better understanding of electric cables. Underground feeder (UF) cables In this type of cable, the wires are not wrapped individually but grouped together and embedded into a flexible material. These are some of the best electric cables to use outdoors as they are water-resistant. They can be used for lighting signboards and, as the name suggests, are usually buried in the ground. Multi-conductor cables Commonly chosen for electrical work at homes, multi-conductor or multicore cables consist of more than one individually insulated conductor. Plus, they also have another top layer of insulation for extra safety. Multi-conductor lines come in varieties such as the audio multicore cable or “snake cable.” Armored cables These cables come in steel or aluminum jackets and are incredibly durable. Hence, they are used in places where the risk of wires being damaged or pinched is high—for example, locations with rodents or the risk of fire or explosion. Nonmetallic sheathed cable Also referred to as NM cables, these have two to four wires and one bare wire for grounding.
