4. Design Advantages:  

  Gray Silicone:Resists tracking and erosion better than traditional porcelain.  

  Lightweight:Easier to handle and install compared to ceramic insulators.  

  Corrosion-Resistant Metal Fittings:Zinc-coated or stainless steel for durability.  


Typical Applications:

1. Overhead Distribution Lines (15kV Class):

 Used in **rural electrification, urban power networks, and industrial power lines where

pollution or salt fog is a concern.  

2. Railway Electrification Systems:  

 Suitable for catenary suspension in railway overhead lines due to its vibration

resistance and mechanical reliability.  

3. Renewable Energy Projects:  

 Commonly applied in solar farm grid connections and wind farm collector line where lightweight and pollution resistance are critical.  

4. Harsh Environments:  

 Coastal zones (salt fog)  

 Industrial areas (chemical pollution)  

 Desert regions (sand and dust)  

5. Temporary Power Installations:  

 Used in emergency power restoration due to quick installation and durability.  


Why Choose This Insulator?  

Longer service life than porcelain insulators.  

Maintenance-free performance due to silicone’s self-cleaning properties.  

Cost-effective over time with reduced replacement needs.
