Structure and Materials

Insulator Structure Details
Anti-Pollution Toughened Glass Insulator

🔹 Glass Umbrella Tray

Utilizes high-strength tempered glass with enhanced thermal and mechanical resistance. Its smooth, hydrophobic surface minimizes dirt adhesion and excels in anti-pollution performance. Includes a "Zero-value self-explosion" feature for easy fault detection.

🔹 Metal Accessories

Caps and feet are made from hot-dip galvanized steel or aluminum for superior corrosion resistance, bonded securely via cement adhesive. Standardized locking pins ensure reliable string connections.

🔹 Umbrella Skirt Design

Inclined design promotes rainwater runoff and natural cleaning. Optimized multi-layered spacing increases creepage distance, prevents rainwater bridging, and minimizes corona discharge or partial discharge risks.

Frequently Asked Questions (FAQ)

What does the U100BS model designation mean?
The "U" stands for Disc Suspension Insulator, "B" indicates the Ball and Socket connection type, and "S" signifies a Short Steel Foot design.
What is the advantage of the toughened glass used in these insulators?
Toughened glass provides high mechanical strength, excellent thermal shock resistance, and a smooth hydrophobic surface that prevents dirt accumulation and improves anti-pollution performance.
How does the "Zero-value self-explosion" feature work?
If the glass insulator loses insulation due to a fault, the umbrella disc bursts automatically. This visual indicator allows maintenance crews to quickly identify and replace the faulty unit.
Are these insulators suitable for high-pollution environments?
Yes, the inclined umbrella skirt design and multi-layered spacing increase the creepage distance and facilitate self-cleaning by rainwater, making them highly effective in polluted conditions.
Which international standards do these products follow?
Our insulators comply with major standards including IEC60305, GB/T 7253-2005, IEC60120, and BS 3288 part III, ensuring global compatibility and reliability.
Can I choose the type of locking pin?
Yes, according to specific project or customer requirements, the insulators can be supplied with either a W-pin or an R-pin locking mechanism.
