Electrical (wires and cable)

Electrical wires and cables are essential components in the transmission of electricity, enabling the safe and efficient flow of electrical energy across various systems. Wires are typically made of conductive materials such as copper or aluminum, with copper being the most commonly used due to its superior conductivity. The wire itself is usually coated with insulation to prevent electrical shorts and protect users from electric shock. Electrical wires come in different gauges (thicknesses) to handle varying levels of current, and they are often classified by their specific applications, such as power, control, or communication.

Cables, which consist of multiple wires grouped together and often enclosed in a protective sheath, are used for more complex applications. There are different types of cables designed for specific environments or uses, such as power cables, data cables, and coaxial cables. Power cables are used to transmit electricity from one point to another, while data cables, like Ethernet or fiber-optic cables, are used to transmit signals for communication purposes. The insulation around wires and cables is made from materials like PVC (polyvinyl chloride), rubber, or thermoplastic elastomers, designed to provide durability, fire resistance, and protection against external elements like moisture or chemicals. Electrical wires and cables are fundamental in nearly every modern infrastructure, from residential wiring and industrial machinery to communication networks and transportation systems
