- Structural Composition
- Glass Fiber Epoxy Resin Pulled Rod: Serving as the core rod of the insulator, it has a very high tensile strength and bending strength. Its tensile strength can reach more than 1000MPa, with a high specific strength, which is about 5 to 10 times that of high-quality carbon steel. It can provide good mechanical support for the insulator.
- Silicone Rubber Umbrella Skirt: Made of silicone rubber material, it has good hydrophobicity, anti-aging property, resistance to tracking and electrical erosion. The design of the umbrella skirt can increase the creepage distance, improve the insulation performance of the insulator. At the same time, it can effectively prevent contaminants such as rainwater and dust from forming a conductive path on the surface of the insulator.
- Fittings: Generally made of hot-dip galvanized cast steel, it is mainly used to connect the insulator with other components such as transmission lines or towers. It has good anti-rust and anti-corrosion performance, ensuring the connection reliability of the insulator during long-term use.

- Technical Parameters
- Rated Voltage: 33kV, indicating that this insulator is suitable for use in a 33kV power system and can work normally at this voltage level to ensure its electrical insulation performance.
- Rated Mechanical Bending Load: 10kN, meaning that the insulator can still maintain its structural integrity and electrical performance stability when subjected to a mechanical bending force of 10kN.
- Structural Height: 406mm, which specifies the overall height dimension of the insulator, and this is of great significance for the space layout during installation and use.
- Minimum Arc Distance: 280mm. When an arc occurs, this distance can ensure that the insulator has sufficient insulation strength and prevent the arc from breaking down the insulator and causing faults such as short circuits.
- Minimum Creepage Distance: 940mm. A larger creepage distance can improve the insulation performance of the insulator in harsh environments such as pollution and humidity, reducing the possibility of tracking and pollution flashover.
- Diameter: The diameter of the umbrella skirt is 122mm/92mm. Such a size of the umbrella skirt can effectively shield rainwater and dust, and is also conducive to air circulation, reducing the surface temperature of the insulator.
- Lightning Impulse Withstand Voltage: 200kV (peak value), reflecting the insulator's tolerance to lightning impulses. It can withstand a lightning impulse voltage of 200kV without flashover or damage.
- 1min Power Frequency Wet Withstand Voltage: 200kV (effective value), indicating that the insulator can withstand a voltage of 200kV for 1 minute in a wet state during the power frequency voltage test without insulation breakdown or flashover.
