Description
1. Core Standards and Specifications
- Reference standard: IEC 60372 / GB/T 4056
- Common specifications: Class 16 / 20 / 24 / 28 / 32 (corresponding to insulator strength classes).
- Scope of Application: Locking connection between the ball and socket of suspension/composite insulators
2. Material Selection
- Stainless Steel: Grade 304 / 316 (preferred for high-salt-mist and coastal environments)
- Phosphor Bronze: Offers Excellent Elasticity and Corrosion Resistance
3. Key Performance Indicators
| Project | Technical Requirements |
| Appearance | Smooth surface, free of burrs, cracks, or rust spots. |
| Flexible reply | After being subjected to the specified displacement and compression, it must fully return to its original state. |
| Corrosion Protection Grade | Stainless steel is naturally corrosion-resistant; bronze materials must meet the requirements of the salt spray test. |
| Compatibility | Strictly conforms to IEC standard dimensions, ensuring smooth installation and secure locking. |
4. Product Advantages
- High reliability: Prevents the insulator string from becoming abnormally detached due to wind-induced vibration or mechanical impact.
- Long service life: Designed to match the service life of the insulator body, meeting operational requirements of 30 years or more.
- Maintenance-free: The material is stable and requires no additional maintenance in harsh industrial or coastal environments.
