Electrical cables come in various types, each designed for specific applications. Coaxial cables, for instance, are commonly used to transmit high-frequency signals, making them ideal for cable television and internet connections. These cables are constructed with a central conductor, an insulating layer, a metallic shield, and an outer insulating layer. Another type, twisted pair cables, are used extensively in telecommunications and networking, such as Ethernet cables. They consist of pairs of insulated copper wires twisted together to minimize electromagnetic interference (EMI). Multi-conductor cables are designed for applications requiring multiple circuits and are commonly found in industrial control systems. These cables contain several insulated conductors bundled together within a single outer jacket. Each type of electrical cable is tailored to meet specific performance criteria and environmental conditions, ensuring reliable and efficient transmission of electrical signals.
