The ignition high-voltage wires in a gas engine are typically made of durable, heat-resistant materials such as silicone or EPDM rubber, often reinforced with fiberglass or other insulating layers. These cables are designed to withstand high voltages, extreme temperatures, and environmental stressors like moisture and vibration. Their primary purpose is to transmit high-voltage electrical energy from the ignition coil to the spark plugs, ensuring precise and reliable ignition of the air-fuel mixture in the engine's combustion chambers. High-quality HT cables minimize energy loss, prevent electrical interference, and contribute to efficient engine performance, smooth operation, and reduced emissions.
