Power cables, also known as electrical cables or power cords, are cables used to transmit electrical energy from a power source to a device or appliance. They are an essential part of the electrical infrastructure and are designed to safely carry electrical current from one point to another.Power cables typically consist of one or more conductors, which are usually made of copper or aluminum. These conductors are surrounded by insulation material, which provides electrical and mechanical protection. The insulation material is usually made of materials like PVC (polyvinyl chloride), XLPE (cross-linked polyethylene), or rubber.The conductors within the power cable can be arranged in different configurations, depending on the intended use and the amount of power that needs to be transmitted. Common configurations include:Single-core cables: These cables have a single conductor surrounded by insulation. They are used for low-voltage applications and are often found in household appliances and electronic devices.Multi-core cables: These cables have multiple conductors within a single cable sheath. They are used for higher voltage applications and are commonly found in industrial settings, construction sites, and power distribution systems.
