Microzip cable consists of 32 AWG solid silver-plated copper. The silver-plated copper is fully extruded with HCM's unique Thermoplastic Olefin. A red polarity stripe is co-extruded into position number one for easy identification. Since the polarity stripe is physically extruded into the edge of position one, no chipping or flaking will occur. No hazardous inks are used for the stripe. Standard color is light yellow with a red polarity stripe (violet for 32 AWG).
