Different Use of Electrical Cables and their Various Types



We never paid much attention to the cables and wires installed in our homes. All we know is that they are one of the essential elements that supply electricity to electrical appliances enabling their proper functionality. There are a plethora of cables available on the market. While some are thick, some cross-connected and some flat in look, each of these has their specific functions, usage, resistance power and induction capacity. Therefore, it becomes imperative to understand the different types of cables available in the market for times when you decide to get them changed in electrical appliances or the cabling of the entire house. 

Non-Metallic Sheathed Cable – Also known as NM cables, they are typically enclosed in a flexible plastic jacket featuring two to four wires and a bare wire for grounding. Specific variants of Non-Metallic Sheathed Cables are used for outdoor or underground use. NM-B and NM-C non-metallic sheathed cables are mainly used for indoor cabling purposes. 

Underground Feeder Cable – Similar to NM cables, they too have two to four cables but instead of being wrapped in thermoplastic, wires are gripped together and embedded in the flexible jacket. Available in many variants, UF cables are used for in-ground applications and outdoor lighting. Their water-resistant property makes them a popular choice. 

Metallic Sheathed Cable – Otherwise known as BX cables, these are used to supply mains electricity or for application in large appliances. Metallic Sheathed Cables feature three plain copper wires which are insulated with cross-linked polyethylene, a black PVC sheathing, and PVC bedding. 

 
Multi-Conductor Cable – This is one of the most common types of cable used at homes since they are well-insulated and simple to use. Commonly known as MC cables, these feature more than one conductor which are individually insulated assuring maximum safety. Variants include – multicore snake cable, typically used in the music industry, etc.

Coaxial Cable – These cables come with a tubular insulating layer that safeguards an inner conductor which is further enclosed by another tubular conducting shield and may also have an extra outer sheath for extra insulation. The cables are known as coaxial because the two inner shields have the same geometric axis.

Ribbon Cable – These are utilized in computers and peripherals. They come with various conducting wires that run parallel on a flat surface resembling like a ribbon. The cables are flexible in nature and can only hold low voltage applications. 

Two- Lead Cable – As the name suggests, these are flat two wire cables which are typically utilized in transmission between antenna and receiver such as radio and television. 

Apart from the cables mentioned above, there are several more types manufactured by cable manufacturers in India for more information click here, which are utilized in a variety of electrical appliances and electrical units. If you still face confusion on which cable to select for your needs and requirements, take the help of an electrician as he an expert with in-depth knowledge of cables and their applications.
