High-voltage Suspension Clamp porcelain insulators are used in high-voltage electrical systems operating in AC systems with nominal voltages above 1000 V and frequencies not exceeding 100 Hz or in electrical distribution devices to insulate and support live conductors (busbars and contacts, etc.).


Stain-resistant outdoor rod-shaped Suspension Clamp porcelain insulators are used on power equipment and devices operating in AC systems with rated voltages of 35 to 500 kV, frequencies not greater than 100 Hz, and pollution levels of Class II and above.

The high-pressure Suspension Clamp porcelain insulator is made of glued by upper and lower metal fittings and insulating parts (porcelain parts). The glue is formulated from Portland cement and quartz sand not less than 42.5. Metal attachments are typically made of cast iron and the Suspension Clamp is coated with anti-corrosive paint or hot-dip galvanized.High-voltage Suspension Clamp porcelain insulators are classified into 7.2, 12, 24, 40.5, 72.5, 126, 252, 362 and 550kV according to the rated voltage, and the indoor insulators only produce 7.2 to 40.5kV.
