Advanced Features: 1. [Tinned Copper Conduction]: Resists oxidization and corrosion.2. [Utral Flexible Silicone Insulator]: High Flame Resistance, High Flexibility, High Thermal Resistance, Chemical Insulation3. [Two colors jacket]: Easy polarity identification. More details: [Quality Material]: 99.9% high purity oxygen-free copper, low resistance, stable transmission; use of non-powdered silicone, more flame retardant.[Strict Quality Control]: To ensure the electrical safety of each wire, we have gone through a series of scientific tests, passing the conductor resistance test, insulation resistance test, specific gravity test, voltage resistance test, wire elongation test, wire rocking and bending test, air exchange aging test and flame retardant test, and SGS tested.
