Product Introduction:
This product is a 33kV Composite Pin Insulator, a key component designed for medium-voltage overhead power distribution systems. Its construction from advanced polymer materials and its specific design features make it a superior choice for modern electrical networks.
This 33kV Pin Insulator is a robust, modern solution designed for reliability in demanding environments. Its primary application is in medium-voltage overhead distribution networks, where its pollution resistance, durability, and excellent electrical insulation properties ensure a safe and continuous supply of electricity.

Specific Introduction:
1. Core Construction (Composite Material):
Unlike traditional porcelain or glass insulators, this unit is manufactured from a Polymer/Hydrophobic Composite Material (typically silicone rubber). This material is key to its advanced performance:
Lightweight: Significantly lighter than porcelain equivalents, making transportation and installation easier and safer.
High Mechanical Strength: The core is a strong fiberglass rod that provides the specified 10kN (approximately 1,020 kgf) cantilever strength, allowing it to withstand mechanical loads from conductors and environmental forces.
Hydrophobicity: The silicone rubber material naturally repels water. This prevents the formation of a continuous water film on the surface, which greatly improves pollution flashover performance.
2. Electrical Specifications:
Rated Voltage: 33 kV (Kilovolts). This indicates it is designed for electrical systems with a nominal voltage of 33,000 volts.
Creepage Distance: 1100 mm. This is a critical parameter representing the total path length along the insulator's surface between the conductive parts (top and bottom). This long path is essential for preventing flashover—an electrical discharge over the surface—especially in polluted or humid conditions.
3. Unique Shed Design:
“Grey Big-Small Shed” Arrangement: The insulator features 11 alternating sheds of two different sizes and profiles. This sophisticated design is not merely aesthetic; it serves important functions:
Improved Pollution Performance: The variation in shed size disrupts the airflow and reduces the accumulation of contaminants (dust, salt, industrial pollution).
Enhanced Self-Cleaning: The design promotes better washing during rain.
Optimized Dielectric Strength: It increases the overall surface leakage path (creepage distance) without unnecessarily increasing the insulator's height.
4. Mechanical and Mounting Features:
Mechanical Load Rating: 10 kN. This signifies the insulator can withstand a mechanical failing load of 10 kiloNewtons.
Hardware: The insulator is equipped with M22 threaded studs at both ends. The top stud is integrated into a metal cap for attaching a conductor clamp (as mentioned, it comes with a clamp), while the threaded metal pin at the base is for securely mounting the insulator to the cross-arm of a utility pole.
Primary Application Scenarios:
This composite insulator is typically used to securely attach and insulate electrical conductors from the supporting utility poles or cross-arms. Its main application scenarios include:
Distribution Lines on Poles: It is predominantly used in 11kV, 33kV, and sometimes 66kV overhead distribution lines, often seen running along roadsides or across fields. The insulator is mounted directly onto the pole's cross-arm using its bottom M22 threaded stud. The power conductor is then secured in the clamp attached to the top eyelet.
Areas with High Pollution or Salinity: The 1100mm creepage distance and the hydrophobic (water-repellent) nature of the silicone rubber make it exceptionally resistant to flashovers caused by contamination. This is critical in industrial areas, coastal regions with salt fog, or arid environments with dust, where pollution can easily accumulate on insulator surfaces.
Lightning-Prone Regions: The composite material provides better performance than porcelain during lightning-induced surges. Additionally, the design helps mitigate the risk of puncture damage.
Locations Requiring Vandal Resistance and Lightweight Construction: Its high mechanical strength (10kN rating) and non-brittle composite body make it more resistant to damage from gunshots or impacts compared to porcelain insulators. Its light weight also simplifies installation, especially in remote or difficult-to-access terrain.
