UL 3135 Wire 20awg Silicone Rubber Insulated Wire
20AWG UL3135 wire features 26 strands of highly flexible copper conductors with a diameter of approximately 0.16 mm, for an overall diameter of approximately 0.94 mm. The cable offers excellent conductivity and oxidation resistance. The outer layer is insulated with high-quality silicone rubber, which is flexible and resistant to bending, making it easy to route and install. It is rated for 600 V and has a maximum operating temperature of 200°C. It exhibits excellent flame retardancy (VW-1), chemical resistance, abrasion resistance, and aging resistance, ensuring long-term stable operation in harsh environments such as high temperature, vibration, and humidity.
