Core Features and Technical Advantages:
- Superior Dielectric Strength: The high-strength tempered glass construction provides excellent insulating properties, effectively preventing flashovers and leakage currents even under polluted or humid conditions.
- Optimized 210mm Creepage Distance: This specific design offers an ideal balance between performance and size, providing sufficient surface leakage path to maintain insulation in medium to high pollution zones.
- High Mechanical Strength: Manufactured to withstand significant tensile and compressive loads, ensuring structural integrity under the weight of conductors and during high-wind events.
- Transparency for Easy Inspection: The clear glass body allows for quick visual inspection of the insulator's condition. Cracks or defects are easily identifiable without specialized equipment, facilitating proactive maintenance.
- Excellent Weathering Resistance: The glass material is inherently resistant to UV radiation, temperature cycling, and chemical corrosion from industrial or coastal atmospheres, ensuring long-term performance stability.
- Hydrophobic Surface Properties: The smooth glass surface promotes water sheeting, reducing the risk of dry band formation and subsequent arcing, which is crucial for maintaining performance in wet conditions.

Frequently Asked Questions (FAQ)
Q1: What is the primary application voltage range for the U70BS 210 insulator?
A1: The U70BS 210 is designed for use on high-voltage transmission lines. The exact system voltage it is applied to depends on the number of insulator units used in a string and the local pollution conditions. It is a standard disc insulator suitable for common transmission voltage levels.
Q2: How does the 210mm creepage distance benefit performance?
A2: The creepage distance is the shortest path along the insulator surface between the metal parts. A 210mm distance provides a sufficient leakage path to withstand surface contamination (like dust, salt, or industrial pollution) and moisture, preventing flashover and ensuring reliable insulation in areas with moderate pollution severity.
Q3: Is the transparent glass as strong as colored or toughened glass insulators?
A3: Yes. The transparency is a result of the high-quality glass composition and tempering process. The mechanical and electrical strength is inherent to the tempered glass material itself and is not compromised by its clarity. It meets all standard mechanical load (70kN) requirements.
Q4: Can these insulators be used in coastal or heavily polluted industrial areas?
A4: The 210mm creepage distance makes it suitable for areas with medium pollution severity. For very heavy pollution (seacoast or heavy industry), insulators with a longer creepage distance or special anti-pollution designs might be recommended. We can advise on the best product for your specific site conditions.
Q5: What quality certifications are associated with your production?
A5: Our manufacturing facility operates under an ISO9001 Quality Management System. This certification ensures consistent processes, material control, and final product testing, providing assurance of product reliability and performance.
Q6: What is the packaging for export, and what are the main shipment ports?
A6: Insulators are typically packed in sturdy wooden crates or cartons to prevent damage during transit. We ship from major Chinese ports including Shanghai, Tianjin, Guangzhou, and Ningbo, offering flexibility and efficiency for global logistics to all our main markets.
Q7: Do you offer other types or sizes of glass insulators?
A7: Yes. As a manufacturer, we produce a range of suspension disc insulators with different mechanical ratings (like 120kN, 160kN) and creepage distances to suit various voltage levels and environmental conditions. Please inquire for our full catalog.
Q8: What is the typical lead time for an order?
A8: Lead time depends on order quantity and current production schedule. Standard products often have stock availability, while large custom orders require production time. We provide specific lead time quotations upon receiving your detailed inquiry to ensure timely delivery.
