High-fidelity sound equipment power line and preparation method thereof

The invention discloses a high-fidelity sound equipment power line. The power line comprises a silica gel strip, a power line center main body layer, a polyester belt layer, a first PVC layer, a pure copper net layer, a second PVC layer and a cotton weaving layer which are successively arranged from inside to outside. The power line center main body is formed in a way that 17 single-strand metal wire tubes surround the periphery of the silica gel strip successively. The invention also discloses a preparation method of the high-fidelity sound equipment power line. The preparation method comprises steps of (1) preparing an alloy wire; (2) cutting; (3) winding; (4) sleeving a PVC heat shrinking tube; (5) sleeving a pure copper shielding net; (6) sleeving a PVC heat shrinking tube; (7) sleeving pure cotton shock-absorbing net; (8) adding PVC heat shrinking tubes on two ends; (9) threading; (10) threading alloy wires. According to the invention, the power line is a power line specially prepared for sound equipment
