1. Wires and cables are used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables, which can be defined as: a collection composed of the following parts Body; one or more insulated cores, and the covering, general protective layer and outer sheath they may each have. Cables may also have additional uninsulated conductors. Wire products used to transmit electromagnetic energy, information and realize electromagnetic energy conversion.
Wires and cables in a broad sense are also referred to as cables, and cables in a narrow sense refer to insulated cables. It can be defined as a collection of the following parts: one or more insulated cores, and each may have a covering layer, a total protective layer and an outer sheath. The cable may also have additional uninsulated conductors.
The main differences between the two lie in the following aspects:Construction:
Electrical wires typically consist of one or more conductive metal wires, which may be solid, stranded, or braided with metal foil. Cables consist of one or more insulated conductor cores, each of which is wrapped by an insulating layer and has a protective layer on the outside.
Purpose:
Wires are mainly used to conduct electricity and carry current. They can be used in the manufacture of electrical equipment, motor components and connecting wires. Cables are used to transmit and distribute electrical energy or transmit electrical signals, and are widely used in power systems, communication networks, automobiles, aerospace and other fields.
Size:
Wires are usually thin and have a smaller diameter, making them suitable for routing in tight spaces. Cables are usually larger and thicker in diameter, and are suitable for larger power transmission and long-distance transmission due to their complex structure and multiple insulated conductor cores.
Insulation:
Wires generally have insulation to prevent current leakage or short circuits. Each conductor core of the cable has an independent layer of insulation to ensure electrical isolation and protection between conductors.
Application scope:
Electrical wires are usually used in low-voltage and low-power applications, such as household electricity, low-voltage appliances, etc. Cables can be used for low, medium and high voltage transmission lines, communication cables, industrial equipment and other needs.
