HIGH QUANLITY: It is made of 6x17 tinned copper wires and high-quality PVC. It has the characteristics of 80° high temperature resistance, strong toughness, acid and alkali resistance and moisture resistance. CONVENIENT TO USE: Easy to solder, peel and cut. High conductivity, low resistance (tin is very thin, 99.99% is copper) and flexibility, it can be twisted and stretched at will. WIDELY USED: it is a tinned copper wire, it can be easily welded with a 22awg connection extension cable for 3014/5050/3528/2535 rgbcct led strips. Of course, as long as it is a low-voltage product, such as: for electronic products, LED bulbs, light strings, car connections, CB radio and audio connections, and other low-voltage 5,12V 24V product connections (wattage
