Differences between speaker cables (also known as audio cables) and power cables:

Purpose: Speaker cables are used to connect amplifiers to speakers, transmitting audio signals which are much larger than those in video and audio cables. Power cables, on the other hand, are used to transmit electrical energy.

Material: The metal used in the core of speaker cables is usually of higher quality and purity, resulting in lower resistance and minimal loss in audio transmission. Power cables do not have such stringent requirements.

PE

Transmission Effects: Speaker cables have low resistance, resulting in minimal loss in audio transmission. Power cables and speaker cables have different transmission paths and cannot guarantee the distortion index required by the audio system.

Safety: The insulation voltage resistance of speaker cables is lower than that of power cables because the output voltage of audio is generally not high. Using speaker cables as power cables can pose a risk of insulation breakdown and fire over long-term use.

Conductivity: Speaker cables, especially those made of oxygen-free copper, have high purity, flexible wire diameter, and good conductivity. Ordinary power cables have a simple structure, usually a single copper wire, which is harder and has higher strength compared to speaker cables, but their conductivity is far inferior.

In conclusion, while both types of cables can establish effective circuits and allow for the transmission of audio signals, their different functions, performance indicators, and safety standards make them non-interchangeable. It's always important to choose the appropriate cable for different usage scenarios to achieve the best results.
