Tension Composite Insulator
We product various types of tension composite insulator include pin insulator has good damping,creep resistance,fatigue resistance,fracture resistance ,high temperature resistance,stress corrosion resistance etc.
1.Technical data of tension composite insulator
Rated mechanical tension load
Min nominal creepage distance
1min power frequency wet withstand voltage (kV)
Full wave lightning impulse withstand voltage peak value (kV)
The silicone rubber sheds adopt overall injection pressure process, so solve the reliability of composite insulators problem of the interface electrical breakdown. The core and the metal fittings using the most advanced technology, high strength, good looks, small size, light weight, corrosion-resistant galvanized fittings, the product structure, reliable, does not damage the mandrel, give full play to its mechanical strength. Silicone rubber sheds with good hydrophobic properties, the overall structure ensures that the insulation does not get wet, no preventive insulation monitoring tests, no cleaning, reducing routine maintenance.
l Light weight (65-80% less than ceramic insulator).
l Silicon rubber sheds provide perfect hydrophobic performance, good resistance to ageing, tracking and erosion.
l Stable behaviour at extreme climatic conditions.
l Long term surface hydrophobicity.
l Suitable for polluted environment, salty atmospheres etc.
