Structure and materials
-
Glass umbrella tray
High-strength tempered glass is used, and its mechanical properties and resistance to thermal and cold shock are improved through a heat treatment process.It features a smooth surface with strong hydrophobic properties, making it difficult for dirt to adhere, and it offers excellent anti-pollution performance.Zero-value self-explosion characteristic: In the event that the glass insulator loses its insulation due to a fault, the umbrella disc will burst automatically, allowing operation and maintenance personnel to quickly identify the fault point. -
Metal accessories
Cap&foot: Manufactured from hot-dip galvanized steel or aluminum, these components are corrosion-resistant and are securely bonded to the glass umbrella tray using cement adhesive.Locking pin: Featuring a standardized design, it ensures a reliable connection for the insulator string. -
Umbrella skirt design
The umbrella skirt features an umbrella-shaped, inclined design that facilitates the sliding down of rainwater and aids in the washing away of dust and dirt by rainwater, thereby reducing the accumulation of grime. The umbrella skirt's roomy design prevents rainwater bridging and ensures insulation performance.The appropriate spacing between the multi-layered umbrella skirts increases the creepage distance and prevents flashover. It also prevents rainwater bridging, further enhancing the creepage distance and improving insulation flashover resistance. The spacing design promotes air circulation, reducing the risk of partial discharge, features smooth edges to minimize electric field concentration, and prevents corona discharge.

Packaging method
1. High Mechanical Strength
Rated Mechanical Load: The "100" in the model number signifies a rated mechanical load of 100 kN (approximately 10.2 tons), making it appropriate for long-span or high-tension power lines.
Structural Design: Composed of high-strength porcelain or tempered glass, with steel pins and caps securely bonded through cementitious assembly to guarantee load-bearing capacity.
2. Excellent Electrical Performance
High Flashover Voltage: The shed design, typically standard or anti-pollution type, effectively extends the creepage distance, providing high wet power-frequency withstand voltage and lightning impulse withstand voltage.
Arc Resistance: The material resists arc erosion, ensuring long-term outdoor operation.
3. Environmental Adaptability
Pollution Resistance: When designed as an anti-pollution type (e.g., U100BSP), the more complex shed profile (e.g., deep ribs) increases the creepage distance, making it suitable for industrial or coastal areas with high contamination levels.
Weather Resistance: Materials such as porcelain or glass are resistant to UV radiation, temperature fluctuations, and chemical corrosion, ensuring performance in harsh climates.
4. Reliability & Durability
Zero-Value Self-Destruction: Tempered glass insulators shatter upon failure, facilitating visual inspection, whereas porcelain insulators necessitate regular testing.
Long Service Life: Engineered for a service life exceeding 30 years with minimal maintenance requirements.
5. Standardization & Compatibility
Compliance: Meets GB/T 1001.1 (China) or IEC 60383 (international) standards, ensuring interchangeability with other suspension insulators.
Connection Structure: Features standardized ball-and-socket connections for easy hardware assembly.
6. Cost-Effectiveness
Although the unit cost may be higher than that of standard insulators, its extended lifespan and low maintenance requirements reduce lifecycle costs.
Applications
Widely used in transmission lines ranging from 110 kV to 500 kV, particularly in challenging environments such as heavy ice zones, long spans, or coastal areas.
Note
Specific parameters, such as creepage distance and weight, should be verified with the manufacturer's datasheets, as there may be slight variations among different brands.
For comprehensive technical specifications, including dimensions and electrical test values, please specify the particular brand or standard being referenced.
