Between 33kv to 66kv voltage rating cables are called extra high tension cables. Such cables usually consist of a core embedded in a series of protective layers. The layers in the cable allow the metal core to conduct electrical current securely in the location it is installed in. The number and type of protective layers surrounding the core depends upon the use for which the cable is intended. Tri core conductors are used in the 415V - low voltage system. Copper and Aluminium conductors are the two types of electrical cables used in the electrical wiring. Fire Resistant : The cables which are installed should be resistant to fire accidents. Electrical Wiring: a set of phase and neutral conductors installed as a group to supply power to a location and which originate from one protective device. For domestic Premises, all wiring supplying one room must be on the same phase, what is electric cable other than for kitchens and for ceiling lighting. Strength and flexibility : The cables which are used for any purpose must have a large insulation and should be easily installed. Cables must not be installed in lift shafts other than those serving lift functions.

These cables include several conductors which are protected through an external coating known as insulation. In no case shall a feeder for an individual dwelling unit be required to have an ampacity greater than that of its 310.15(B)(7)(a) or (b) conductors. For application of this section, the main power feeder shall be the feeder(s) between the main disconnect and the lighting and appliance branch-circuit panel board(s) and the feeder conductors to a dwelling unit shall not be required to be larger than their service entrance conductors. May be allowed only for insulated and sheathed or flexible conductors which will remain accessible but in locations free from undue risk of damage or interference (e.g. above-head height, or in unoccupied areas). W - Wet, this wire is also appropriate for dry locations. Power cables are mainly used for electric power transmission from substations to necessary locations. Mims cables provide an ageless, fireproof & lifetime electric cable solution.

These cables are available in two types gas pressure and oil-filled. There are different types of cables available in the market which are used based on the requirement. Power cables operate on direct current or low-frequency alternating current, while communication cables operate at higher frequencies. These cables are very popular due to moisture, changes from high tolerance to temperature & other ecological factors for transmission or communication requirements. Electric communication cables transmit voice messages, computer data, and visual images via electrical signals to telephones, wired radios, computers, teleprinters, facsimile machines, and televisions. A thick wire or a set of wires in a plastic or rubber covering is used to carry electricity for transmission & distribution to homes, industries, etc is known as cable or electric cable. An electrical cable is an assembly of one or more wires running side by side or bundled, which is used as an electrical conductor to carry electric current. These cables include one or more wires and are coated with plastic material. In Europe, this cable can be described more frequently by using the term multicore. These cables are available in small size but we can extend by using some adapters based on the requirement.

These cables are smooth two-wire cables, used for transmission in between an antenna & receiver such as a TV &radio. These conductor in form of a stranded wire which are insulated with a polymer (non-conductive) coating is a wire while a cable is combination of two or more shielded wired with a single cover which is used for generation, distribution and transmission of electrical power. These are very important for various application like power generation, distribution and transmission. These cables are mainly used to connect the keyboard & mouse to the computer system. The USB (Universal Serial Bus) is very popular and standard cable used to connect different peripherals to a computer device. CENELEC HD 361 is a ratified standard published by CENELEC, which relates to wire and cable marking type, whose goal is to harmonize cables. Continuous-flex or flexible cables used in moving applications within cable carriers can be secured using strain relief devices or cable ties. The construction of electric cables can be done by using a copper material because copper is not expensive. The labeling of the electric cables is very significant because it provides information regarding the type of insulation used, the number of cables & the measure of the cables.
