Basic 5N Pure Silver 0.2sq. Conductor Wire Under advanced production control, continuous casting in a high-frequency electric furnace, 19 processes of cold rolling, annealing twice, drawing with a diamond die, and skin-pass treatment are performed to use high-quality “high-purity silver wire” with not only high silver purity but also no gaps at the crystal grain boundaries. The 0.2mm 5N pure silver single wire manufactured under such advanced production control is twisted into 7 strands to secure sufficient cross-sectional area (0.2sq). Conductor resistance is suppressed to the maximum extent. Features Insulation Materials Double insulation is used for the insulator by means of silk threads. The purpose of adopting natural materials is to prevent static electricity generated in analog playback from being charged and to ensure clean signal transmission. Resin-based materials (PVC, fluoroplastic, etc.) are easily charged with static electricity due to the action of a negative charge. Silk, on the other hand, is a material that is not easily charged with static electricity and has excellent electrical properties. Similarly, the glass fiber sleeve used for the exterior is a material with high insulating properties and low static charge. Shell Tip Contact The shell tip attached to the terminal uses highly springy phosphor bronze as the base material to improve adhesion with the contact pin. In addition, rhodium plating is used on the surface to prevent oxidation.
