Specification30ft 22AWG Gauge 2 conductor wire(Red & Black ). Rated voltage: 300V. Rated temperature: 80/176. Cond.resistance: 59.4/KM20, Insulation resistance: 10M/KM20, Dielectric test: 2000AC V/min.Material:PVC+Tinned Copper+AL Excellent shielded effectThere are double shielded layers(Aluminim& tinned copper) to achieve premium shielded effect. The shielding layer can shield this electromagnetic field inside the cable. Shielded cables also serve as grounding protection: if there is damage to the core wire of the cable, the leaked current can flow along the shielding layer, such as the grounding grid. At this point, shielded cables serve as safety protection. High ConductivityTinned copper not only has good electrical conductivity, but the tin coating also has the characteristics of strong corrosion resistance and oxidation resistance.It can greatly extend the service life comparing with ordinary copper wire. It is also more suitable for soldering. High quality c
