Kind. It is mainly used in power lines, control lines and signal transmission lines for electrical appliances, instruments and electronic equipment and automation devices, and can be used for anti-theft alarm systems and building intercom systems. The rated voltage is 300V/500V, the number of cores is from 2 cores to 24 cores according to the national standard color separation, the two cores are twisted and combined, and the outer stranding direction is right direction.

Looking at the length of the line (100 meters in a circle), the national standard line is 95-100 meters, and the non-standard line is about 90 meters.
