What Are Cables?
Cables are assemblies of multiple conductive wire cores and insulation layers, primarily used to transmit power, communication signals, and data. Depending on their use, cables can be classified into the following types:
1. Power Cables: Used for transmitting high and low voltage power. Common types include copper-core and aluminum-core cables, usually wrapped in thick insulation to ensure safe current transmission.
2. Communication Cables: Used for transmitting phone and network signals. Common types include coaxial cables and twisted pairs.
Cable Structure?
1. Conductor: Usually made of copper or aluminum, responsible for conducting current.
2. Insulation Layer: Wrapped around the conductor to prevent current leakage and ensure safety.
3. Shielding Layer: Prevents external electromagnetic interference; some high-demand cables have this protection.
4. Sheath: The outermost layer, protecting the cable from mechanical damage and environmental impact.
