Silicon wire refers to a type of wire that has a silicon insulation coating. The "10AWG" specification indicates the wire's gauge size, specifically 10 American Wire Gauge (AWG). AWG is a standard system used to measure the diameter or thickness of wires. In the AWG system, a lower number corresponds to a thicker wire. So, 10AWG wire is thicker than. Silicone wire and cable is an excellent choice for high temperature, high voltage, low corona, and applications requiring extremely flexible wire or cable. Silicone is used in implantable and medical grade wire and cable applications. It is also used in aerospace, military, and space applications.
