High Voltage Railway Insulator
High voltage railway insulator with superior hydrophobicity/anti-water performance.
1.Technical data of high voltage railway insulator
Rated mechanical bending load
Min nominal creepage distance
1min power frequency wet withstand voltage (kV)
Full wave lightning impulse withstand voltage peak value (kV)
2.Materials of high voltage railway insulator
1.We use HTV silicone rubber which hydrophobicity can reach to HC1 level.
2.We use hot dip Galvanizing steel fitting ,the thickness of the zinc more than 100 μm.
3.We use ECR rod as the core which is high acid resistant. 7200Hr testing passed.
4.Good anti-vibration capability.
5.Good anti-moisture capability.
6.Electric corrosion resistance.
7.Excellent corona resistance.
