The 33kV-70kN eye-eye suspension type composite polymer insulator has the feature of light weight, small volume, not easily broken, high mechanical strength, high pollution resistant, good aging resistance, high anti explosive and others.The surface of terminal end fittings is covered with hop-dip galvanized for corrosion protection.
1. Lightweight: Composite polymer insulators are significantly lighter than their porcelain or glass counterparts. This characteristic simplifies installation, reduces the mechanical stress on support structures, and minimizes the overall weight of the transmission line.
2. High Mechanical Strength:The composite materials used, often a combination of fiberglass and polymer matrix (such as silicone rubber), provide excellent mechanical strength.
3. Corrosion Resistance: Composite materials are generally more resistant to corrosion than traditional materials like porcelain. This resistance enhances the durability and longevity of the insulator, especially in challenging environmental conditions.
4. Excellent Pollution Performance:Polymer insulators typically exhibit superior pollution performance compared to porcelain insulators. The hydrophobic nature of the materials helps prevent the accumulation of contaminants, reducing the risk of flashovers in polluted environments.
5. Flexibility and Design Options: Composite insulators can be designed with specific shapes and flexibility, allowing for better adaptation to various installation conditions. The eye-eye suspension type provides a flexible connection point that accommodates movement and thermal expansion in the system.
6. High Electrical Insulation Performance:Composite polymer insulators maintain excellent electrical insulation properties, ensuring reliable performance in high-voltage applications.
