Rubber is widely used in electrical appliances, mainly in the following aspects:

Wire and cable insulation: Rubber, especially natural rubber and silicone rubber, is widely used as the insulation layer of wires and cables to prevent current leakage and ensure electrical safety.
‌High-voltage equipment insulation pads: Rubber materials are used to make insulation pads for high-voltage electrical equipment, effectively isolating potential differences and preventing electric shock accidents.
‌Electronic component sealing: Rubber seals are used to prevent moisture, dust, and shock of electronic components while providing electrical insulation protection.
‌Rubber joint application: In electrical equipment systems, rubber joints are used as flexible connections between pipes to solve pipe stress problems and protect equipment and pipe stability.

In addition, rubber must also have good UV resistance, ozone resistance, and aging resistance in electrical applications to ensure its long-term stability and reliability. The selection and manufacturing process of rubber materials need to be adjusted according to specific application requirements to meet the performance and safety requirements of electrical equipment.
