UF, or underground feeder cables, are common for running power to a shed or garage, and metal sheathed cables such as BX are common for outdoor use.4. These cables include heavy metalcore with different banded metal sheathing layers, gel, for shock-absorbing, thread-fortified tape wrapped by waterproof & heavy rubber coverings. These wires are protected with PVC bedding black PVC sheathing & cross-linked polyethylene. Those are XLPE (Cross linked polyethylene) and PVC (Polyvinyl chloride). A common material like polyvinyl chloride (PVC) is used for the sheath. These cables include one or more wires and are coated with plastic material. These types of cables contain flexible plastic jackets including 2 to 4 wires and also a bare wire used for grounding. 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.

In the electric sector, electric wires and cables play a key role in transmitting & distributing power to industries, houses, offices, etc. Most of the fields depend on different types of electric cables to provide an uninterrupted power supply. The insulation material can get damaged due to overheating which can cause a short circuit, fire, or electric shock. In Europe, this cable can be described more frequently by using the term multicore. Sometimes, a coaxial cable is also called heliax which includes an insulating layer. Alternative of coaxial cable is twin axial cable that includes two conductors rather than one. The paired cable includes two conductors which are insulated individually. Conductor: The conductor material allows the flow of electricity and the conductors used in the cable are copper & aluminum. This cable uses an external sheath for additional insulation. Unlike an aerial cable, a buried cable invariably uses commercially pure copper or aluminum (mechanical strength is not a problem underground), what are electric cables and the stranded conductor is frequently rolled to maximize its compactness and electrical conductance. In other words, every wire is a cable, but not every cable is a wire.Most of the time, anything that isn’t a single conductor with or without insulation is referred to as a cable.

Single core cables are having only one core conductor itself and big sized and that would be Phase, Neutral or Earth. Tri core conductors are used in the 415V - low voltage system. 100 conductors which are twisted in pairs. Gas pressure cables are applicable for up to 275KV whereas oil-filled cables are applicable for up to 500KV. Oil-filled cables are available in three types self-contained circular type, flat type & pipe type. The most common type of indoor residential cabling is NM-B & NM-C non-metallic sheathed cables. Some of the common labels written on cables are THHN, THWN, THW & XHHN. SWG ranges from 7/0, representing .500″, to 50 SWG, representing .0010″.The most common system outside the US is IEC 60228, which defines a standardized set of wires based on their cross-sectional area in mm2. Insulator: Insulator material is used to maintain the conductors alienated from each other to avoid un-intended lanes for the flow of current, the wires are protected through insulating materials like different synthetic polymers. For fixed wiring within Premises, PVC, rubber or XLPE (Cross linked Polyethylene) insulated cables with stranded copper conductors must be used, complying with electrical standard.

The cables that include three conductors which are bunched together & enclosed with an insulating paper ‘belt’ are known as belted cables. Armored cables are more expensive than NM cables, but they’re also sturdier and safer. In these types of cables, every conductor can be insulated with paper impregnated through an appropriate dielectric. Both of these types of insulated wire are often used to connect appliances with branch circuits. These cables are available in different gauge sizes and are used in in-ground & outdoor lighting applications. 6-gauge wire is typically rated for 60 amp circuits, while 8 gauge is usually rated for 45 amps. In the US, the most commonly used wire gauge system is AWG, or American Wire Gauge. Electrical cable is a wire that helps to conduct the current in the circuit. The number of node connections in coaxial cable is limited. These aerial cables consist of a number of wires, usually of copper or aluminum, twisted (stranded) together in concentric layers. 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.
