20KV 660mm Long Rod Suspension Porcelain Insulator

1. Porcelain Body: Made of high-quality porcelain material, providing excellent insulation performance and mechanical strength to ensure stable operation in power systems.
2. Metal Fittings: Equipped with durable metal end fittings that ensure reliable connection with transmission lines and towers, and have good corrosion resistance.
3. Long Rod Structure: The long rod design enhances the mechanical load - bearing capacity, enabling it to withstand the tension and weight of conductors effectively.
4. Umbrella Shape Design: The umbrella - shaped structure on the porcelain body increases the creepage distance, improving the pollution - flashover voltage resistance and ensuring safe operation in polluted environments.

1. Rated Voltage: Capable of withstanding a rated voltage of 20KV, meeting the insulation requirements of medium - voltage power transmission and distribution systems.
2. Lightning Impulse Withstand Voltage: Can withstand high lightning impulse voltage, providing effective protection against lightning strikes in power lines.
3. Power Frequency Withstand Voltage: Exhibits stable power frequency voltage - withstanding capability, ensuring no breakdown under normal power frequency operating conditions.
4. Insulation Resistance: Has high insulation resistance, which helps to maintain good insulation performance during long - term operation.

1. Preparation: Check the insulator for any damage and ensure the mounting hardware is complete and in good condition.
2. Hanging Installation: Use appropriate lifting equipment to hang the insulator between the tower and the conductor, ensuring correct alignment.
3. Connection: Securely connect the metal end fittings of the insulator to the tower and conductor, using suitable connectors and ensuring tight connections.
4. Inspection: After installation, visually inspect the insulator to ensure there is no damage and the connection is secure, and conduct necessary electrical tests if required.

1. Temperature Range: Designed to operate within a wide temperature range, typically - 40°C to + 80°C, suitable for use in various climatic regions.
2. Pollution Resistance: The porcelain material and umbrella shape design make it resistant to pollution accumulation, ensuring reliable insulation performance in polluted areas.
3. Moisture Resistance: Can perform well in high - humidity environments, preventing moisture from affecting the insulation performance.
