Electrical Railway Insulator
Electrical railway insulator is reliable structure, can’t damage the core rod, and take full advantage of the mechanical strength.
1.Size and technical data of electrical railway insulator
|Rated voltage(KV)||Rated mechanical tension load(KN)|
Min nominal creepage distance (mm)
|1min power frequency wet withstand voltage (kv)||Full wave lightning impulse withstand voltage(peak value)|
2.Feature of electrical railway insulator
1).The arcing corona ring well distributes the electric field along the insulator’s axe to prevent corona phenomenon and secure the electrical railway insulator from heavy damage in end fitting in case of flashover.
2).The unique end fitting sealing structure improves product sealing reliability.
3).We use hot dip Galvanizing steel fitting ,the thickness of the zinc more than 100 μm.
4).Our electrical railway insulator are packed in international standard packaging.
5).We have a final inspector manager to check the products on every detail and component to make sure it all meet the drawing.
