Core Structure & Material Advantages
Integrated "insulating matrix + hardware" design, with key components and advantages:
● Insulating Glass Matrix: Tempered high-strength electrical glass forms smooth, dense sheds (drain rain, block arcs, extend creepage distance). Excellent dielectric properties, high insulation resistance, and strong corona/arc resistance.
● Metal Hardware: Weather-resistant alloy steel (iron caps, steel feet) with anti-corrosion treatment. Bonded to glass via high-strength adhesive, ensuring stability under conductor tension, ice and other loads.
● Sealing Structure: Rubber rings at joints block rain/dust, prevent adhesive aging and ensure long-term stable operation.
Quality Assurance & Service
Full-process guarantees centered on power safety:
● Strict Quality Control: Full-process inspection; key indicators certified by third-party authorities.
● Customized Solutions: Exclusive selection and structural optimization based on voltage, environment, etc.
● Full-Cycle Support: Pre-sales parameter interpretation, in-sales installation guidance, 24-hour after-sales response for faults and O&M consulting.
Core Performance Characteristics
Low dielectric loss, stable insulation resistance under HV, resistant to overvoltage. Higher pollution flashover voltage than ceramic insulators, maintaining performance in humid/polluted environments.
Tempered glass with strong flexural resistance; combined with high-strength hardware/adhesion, bears conductor weight, ice and wind loads, and resists breakage in extreme weather.
Smooth surface resists dirt (rain-cleanable); UV, temperature (-40℃~80℃) and corrosion resistant, adapting to salt spray, industrial pollution.
Glass breaks automatically when "zero-value" fault occurs, enabling visual identification and replacement without professional testing equipment.
Chemically stable glass + mature hardware anti-corrosion; 30+ year design life, longer than traditional insulators, reducing replacement costs.
Core Classification & Applications
● High-Voltage (HV): 10kV~110kV, compact structure for medium/short-distance transmission and distribution.
● Ultra-High-Voltage (UHV): 220kV~500kV, multi-piece series connection for long-distance, large-capacity transmission.
● Extra-High-Voltage (EHV): 750kV+, large sheds and high-strength structure for backbone power grids.
● Overhead Transmission Lines: Adapts to mountains, coastal areas, supporting AC/DC transmission.
● Substation Equipment: Insulating support for busbars, disconnectors, ensuring substation stability.
● Special Environments: Customized anti-corrosion, anti-pollution and anti-icing products for extreme conditions.
