High ConductivityHigh precision Oxygen-free copper conducts electricity well. Compared with aluminum materials, it has lower resistance and higher conductivity.Neither cracking at the high temperature, nor would turn hard in the cold. High Quality PVC MaterialThe jacket/insulation materials are PVC(RoHs), which protects the wire against abrasion, resistant to sunlight and chemicals. The rated operating temperature up to 80/176. Rated for OutdoorEngineered to withstand sunlight, abrasion and moist. Approved for direct burial.Maximum working voltage: 300V, Great for uses with 30V or less, Flexible and easy to strip. Widely UseLow-voltage cable extension cords are very suitable for LED monochromatic light strips, electronic appliances and equipment, transformers, spotlights,led lights, led splitter connections, etc. 100% Satisfaction UL listed, RoHS compliant, Fire-proof level:VW-1. All iGreely low voltage landscape wires are backed by our best-in-class guarantee.
