Composite polymer pin insulator post insulator disc insulator ceramic insulator
| Product Name | Pin composite/polymer insulators | Application | Electrified railways |
| Insulator Color | Any color required by the client | Package | Paper tubes Cartons or wooden boxes |
| Suitable standards | IEC 61109/ANSI | Insulator Model | FQX-11kV-36kV |
| Material | Composite/polymer | Relevant Tests | All type tested and design tested |
Applications:
1, Used in distribution lines
Competitive Advantage:
| The advantages of polymer/composite insulators over ceramic/porcelain insulators | ||
| General comparison | ||
| Factor | Ceramic/porcelain insulators | Polymer/composite insulators |
| Weight | Heavy weight- For example 400kV - about 140kgs | 90% lighter than them but with same mechanical strength 400kV -- Around 15kgs |
| Fragility | Highly fragility to shock and vibration | No fragility to shock and vibration |
| Packing and transportation | Risky and very costly | Easy and economical |
| Installation | Risky expensive and more labor required | Very easy and economical |
| Handling | Difficult | Easy |
| Maintenance cost | Very expensive | Low |
| Vandalism | More susceptible | Highly resistant |
| Breakages and secondary damage | Highly fragile- 10-15% breakages are reported during transportation storage and installation | Flexible and therefore highly resistant to breakages |
| Technical comparison | ||
| Mechanical failure | Reduction in mechanical strength and separation during to pings getting eroded | Just with single piece, so no such kind of problem |
| Resistance to flashover and punctures | Low | High |
| Anti tracking and erosion resistance | Very low- poor tracking resistance | Excellent tracking resistance avoids erosion or tracking of the housing material |
| Dielectric strength | Lower than polymer | Excellent insulation performance |
| Contamination and pollution | Highly effected | Not effected and has much longer life |
| Hydrophobicity | No hydrophobicity, ceramic surface forms water films on the surface making easy path leading to more flashover | Very excellent hydrophobicity |
| Self cleaning quality | No, dirty sand salt snow etc are easily attracted | Yes, due to hydrophobicity recovery characteristics |
| Tension strength | Good | Better during crimping technology |
| Maintenance | Needs maintenance like cleaning washing and greasing | Not required at all |
| Safety | Are easy to explosion and breakages due to high fragile properties and stone throwing or gun shooting | Provide very high level of safety superior flexibility and strength. not easy to break due to stone throwing or gun shooting. |
