Suspension Composite Insulator

Key Features

• Superior Electrical Insulation: High dielectric strength and excellent hydrophobicity, effectively preventing leakage current and flashover, even in polluted, wet, or icing conditions. The self-cleaning surface reduces the risk of insulation failure and maintenance frequency.
• High Mechanical Strength: The FRP core provides strong tensile, bending, and torsion resistance, capable of withstanding the weight of conductors, wind loads, ice loads, and other external forces, ensuring stable suspension performance for long-term operation.
• Lightweight & Easy Installation: Significantly lighter than traditional porcelain suspension insulators, reducing the load on transmission towers and simplifying transportation, hoisting, and on-site installation, which greatly lowers construction and labor costs.
• Excellent Weather & Corrosion Resistance: Resistant to UV radiation, moisture, salt spray, chemical erosion, and extreme temperature changes (-40°C to +80°C), suitable for harsh outdoor environments such as coastal areas, deserts, and industrial zones.
• Anti-Pollution & Anti-Icing: The special silicone rubber housing has strong anti-pollution and anti-icing capabilities, effectively adapting to polluted power grids and cold regions, ensuring stable operation in harsh weather.
• Long Service Life: High-quality materials and advanced manufacturing processes ensure excellent aging resistance, with a service life of more than 30 years, minimizing maintenance costs and improving the overall reliability of the power system.

Application Scope

• High-voltage and ultra-high-voltage overhead transmission lines (110kV, 220kV, 500kV, 750kV, 1000kV)
• Medium-voltage overhead distribution lines (10kV, 20kV, 35kV)
• Substation outgoing lines and busbar suspension
• Railway electrification transmission lines
• Industrial and mining power transmission systems
• Coastal, desert, and high-pollution area power grids

Technical Advantages

• Compliant with international standards such as IEC 60815, IEC 61109, and GB/T 19519, ensuring product quality and interchangeability.
• Low electrical loss, stable insulation performance, and strong resistance to electrical breakdown, improving power transmission efficiency.
• No zero-value risk, easy to detect and maintain, reducing the workload of line inspection and maintenance.
• Compact structure, small volume, and strong adaptability to different tower types and installation environments.
• Environmentally friendly and recyclable materials, meeting green energy development requirements.
