The 11KV Silicone Rubber Suspension Insulator (model FXB-11-70CT-330mm) is a medium-voltage component designed for overhead power transmission and distribution lines. It combines reliable electrical insulation with robust mechanical support, featuring a 70kN specified mechanical load (SML) and 330mm creepage distance—ideal for harsh environments. The insulator uses high-grade room-temperature vulcanized (RTV) silicone rubber housing and galvanized steel end fittings, ensuring resistance to UV radiation, ozone, and chemical degradation. Key parameters include a rated voltage of 11KV, lightning impulse withstand voltage of 105KV, and power frequency withstand voltage of 55KV, making it compatible with global 11KV distribution networks.
• Housing: RTV silicone rubber with hydrophobic properties, preventing water film formation and reducing contamination adhesion.
• Core: Fiberglass-reinforced epoxy resin rod (hidden) delivers exceptional tensile strength, supporting the 70kN mechanical load.
• End Fittings: Hot-dip galvanized steel (clevis & tongue design) resists corrosion, ensuring long-term mechanical stability.
Three gray, disc-shaped sheds with precise spacing maximize the 330mm creepage distance, preventing surface tracking. The design also enhances pollution performance by disrupting conductive contaminant buildup and promoting water runoff during rain.
At ~60% lighter than traditional porcelain/glass insulators, it reduces tower load and eases installation. The silicone housing is shatterproof, eliminating risks of fragment injury or line outages from accidental impact.
Hydrophobic silicone minimizes contamination adhesion, eliminating the need for regular washing—cutting maintenance costs and downtime.
For 11KV overhead networks, the insulator provides mechanical support for conductors while insulating against ground potential. Its 70kN strength withstands conductor tension, wind sway, and ice loading, ensuring line reliability in rural or urban areas.
In coastal regions, the 330mm creepage distance resists salt spray deposits that cause insulation failure. In industrial areas, it blocks chemical vapors and dust from compromising performance, reducing line faults.
Within substations, the insulator connects overhead lines to transformers or switchgear, maintaining electrical isolation while withstanding mechanical stress from conductor weight. Its compact design fits into dense substation layouts.
• Standard Compliance: Meets IEC standards for insulators (IEC 60383) and mechanical testing (IEC 61467). Each unit undergoes routine test load (RTL) checks at 35kN to verify mechanical integrity.
• Installation Tools: Compatible with standard clevis-tongue mounting hardware, no specialized tools required.
• Environmental Testing: Validated for UV aging (5,000V per IEC 62217) and salt fog resistance (1,000hr per IEC 60507), ensuring performance in extreme conditions.
• Lifecycle Support: 20-year service life guarantee with periodic performance audits.
• Vandalism Recovery: Replacement parts for damaged end fittings or sheds, minimizing line downtime.
• On-Site Training: Training sessions for installation teams on proper handling and mounting techniques.
