Cable Product Information

What is a stranded cable?
A stranded cable, specifically a twisted pair type, is designed to minimize interference noise. Its unique "star strand" configuration is particularly effective at reducing magnetic interference.
These cables are frequently chosen for professional audio setups because of their ability to minimize interference. They can be used to connect musical instruments, speaker systems, microphones, and other audio devices.
When terminating XLR connectors, stranded star cables can be used to balance microphone connections including condenser microphones that require phantom power. Stranded cables are widely used for this.
Cable with star stranded structure, electrical wiring, high-quality cables for connectivity.

Formula for calculating the area of an audio cable:
For example, take the diameter (d) of a single copper wire of 100 (core) audio cables as 0.1mm. Cross-sectional area formula of a single core: S1=πxR2=πx(d/2)2=3.14x(0.1/2)2
Audio Line Area Formula: S2=S1x100(quantity of audio cable) and 0.1mm copper wire diameter.
Area:
S=3.14x(0.1/2)2x100≈0.8mm2
