Product Details
It prevents fatigue damage, strand breakage and cable failure at suspension points, ensuring safe and stable grid operation.
1. Durable Construction
Hot-dip galvanized ductile iron hammer heads + high-strength steel messenger cable provide excellent corrosion resistance and fatigue performance for long-term outdoor use.
Hot-dip galvanized ductile iron hammer heads + high-strength steel messenger cable provide excellent corrosion resistance and fatigue performance for long-term outdoor use.
2. Efficient Vibration Damping
Classic dual-weight design generates counter-vibration to absorb wind energy, effectively reducing line vibration amplitude and extending service life.
