Suspension Disc Insulators: Reliable Guardians for High-Voltage Transmission
Structure: Cement-bonded assembly of iron cap, toughened glass, and steel foot. Compact cylindrical head design ensures high mechanical integrity. Self-Detection: Shatters automatically upon failure (0.02%-0.04% annual rate), enabling helicopter inspection and cutting manual checks by 90%.
Lightning Resilience: Arc-damaged surface self-restores to smooth glass. Tempered stress layer maintains strength even under vibration. Weather Resistance: Maintains original performance after 30 years. Rain self-cleans surfaces in humid climates.
Anti-Pollution Insulators: Ultimate Solution for Contaminated Areas
Innovation: Optimized shed profile increases creepage distance by 25% (e.g. 400mm for U70BP/146H).
Performance Data: 45kV wet withstand voltage (+12.5% vs standard)
40% higher pollution flashover voltage in salt/industrial zones
Applications: Coastal substations, chemical zones, and high-pollution industrial corridors.
Aerodynamic Insulators: Conquering High-Wind Challenges
Engineering Breakthrough:
- 380mm diameter reduces wind load by 35%
- Lightweight head maintains 100kN strength
Value Proposition:
1. 60% fewer wind-induced failures in gusty areas
2. Ultra-low corona loss (0.5dB) for 500kV+ lines
Ideal for: Mountain passes, river crossings, and UHV transmission projects.
