Wires and cables are common electrical connection devices in our daily lives, playing a crucial role in transmitting power and signals. While they share many similarities, there are also distinct differences. Let's detail the differences between wires and cables below.

1. Structure

A wire consists of one or more conductors, usually with only one layer of insulation, appearing as a single or multiple parallel thin wires. A cable, however, is composed of multiple conductors, typically including conductors, insulation, shielding, and a protective layer, resulting in a more complex structure. Due to its more complex structure, a cable can operate under higher currents and voltages, while also withstanding greater pressure and tensile forces.

2. Function

Wires are mainly used to transmit smaller currents and signals, commonly used in household appliances, lighting, etc. Cables, on the other hand, are primarily used to transmit larger currents and signals, suitable for large equipment, industrial applications, and power transmission. Additionally, cables offer stronger protection and durability, enabling operation in harsh environments while ensuring stable and reliable transmission.

3. Appearance

Wires appear as thin and flexible strands, with a smaller diameter, generally used for low-voltage and low-current transmission. Cables, in contrast, have a thicker and more rigid appearance, with a larger diameter, used for transmitting high currents and voltages. Furthermore, the surface of a cable is often protected by a metal or plastic sheath to prevent external interference and damage.

In summary, while both wires and cables are electrical connection devices, they have distinct differences in structure, function, and appearance. When choosing between a wire or cable, the specific application and requirements must be considered. For applications requiring the transmission of smaller currents and signals, a wire can be selected; for applications requiring the transmission of larger currents and high voltages, a cable is necessary. Environmental factors and operating conditions should also be considered to ensure the safety and reliability of the electrical connection. Hopefully, the above information helps you understand the differences between wires and cables.
