What is the difference between electrical wire and electrical cable?

1. Structure and Dimensions

• Wire: Typically consists of several flexible conductors with an insulating layer on the outside. Wires are smaller in size and have a relatively simple structure.

• Cable: Consists of one or more conductive cores that are insulated from each other, usually surrounded by a protective sheath. Cables are larger in size and have a more complex structure.

2. Purpose

• Wire: Primarily used for transmitting smaller amounts of electricity and signals, suitable for connecting household appliances, indoor wiring, etc. The load capacity of wire is limited, making it appropriate for low-power applications.

• Cable: Used for transmitting and distributing high-power electrical energy or conveying signals. Cables are widely used in power transmission, communication, and other fields, capable of carrying large currents and voltages.

3. Materials

• Wire: Conductive materials are typically copper or aluminum and come in various forms such as solid, stranded, or woven into sheets. The insulation state can be bare or insulated.

• Cable: Also made from materials with high conductivity, but typically has more complex insulation and protective layers to ensure safe and efficient transmission.

4. Features

• Wire: Since it is mainly used for low-power transmission, wire is usually softer and more flexible, making it easy to install and operate.

• Cable: Designed for durability and protection, these are typically harder and can withstand greater mechanical stress and environmental challenges.

5. Hardness

• Wire: Lower hardness, relatively soft, due to its relatively smaller power and current-carrying capacity.

• Cable: Higher hardness and more robust structure, suitable for transmitting high-power electricity and signals.

Summary

Wires and cables, although can be used interchangeably in some cases, it is crucial to choose the right wire or cable due to their significant differences in structure, size, purpose, material, and characteristics in order to ensure the safety and efficiency of the system. In practical applications, selecting the appropriate product according to specific needs is essential to achieve the best results.
