12AWG 4core speaker cable

Conductor Material: Usually oxygen-free copper or tinned copper. Oxygen-free copper has high conductivity and low resistance, which can reduce signal transmission loss and make audio signal transmission clearer; tinned copper has good oxidation resistance, which can extend the service life of the cable and ensure the quality of signal transmission. Structure: It is made of multiple strands of fine copper wires twisted together. This structure makes the conductor soft and easy to bend and install. At the same time, it increases the cross-sectional area, reduces resistance, and improves signal transmission efficiency. Insulation Material: Common ones include polyvinyl chloride (PVC), low-smoke zero-halogen (LSZH) materials, Teflon, etc. Thickness: Generally around 0.8-1.0mm, such as the insulation layer thickness of Belden BE46383 is 3.50mm±0.07mm. The appropriate insulation thickness can effectively prevent short circuits and leakage between conductors, ensure safe use and stable signal transmission. Outer diameter Between 11.00mm-16.00mm. Electrical characteristics Conductor DC resistance: usually up to about 4.5 ohm/km. The smaller the resistance, the smaller the energy loss during signal transmission and the smaller the attenuation of the audio signal, which is conducive to ensuring the clarity and integrity of the sound quality. Rated voltage: generally 300V/500V, which can meet the working voltage requirements of common audio equipment, ensure the stability of the electrical performance of the cable during normal use, and provide reliable power support for the operation of audio equipment. Color Common color identification is wire 1 black, wire 2 red, wire 3 white, wire 4 green, which is convenient for distinguishing different wires, making it easier to correctly wire when connecting audio equipment, making audio wiring clearer and more orderly. Packaging Common packaging specifications are 100 meters/roll, 200 meters/roll, etc. Users can choose packages of different lengths according to actual needs.
