Description:
1, 25kV composite railway insulators are widely used in electrified railways.
2, Dead end fittings are up to the requirements from the clients, usually we use ball, socket, tongue, clevis for tension insulators with forged steel or cast steel. The dimensions and coupling size can be exactly according to the specification requirements from the utilities.
3, The silicon rubber color of the insulators are also up to the requirements from the clients and all the silicon rubber materials past 5000 hours aging test silicon content test and hydrophobicity test.
4, ECR core rods are used in all the insulators, so we can guarantee a very good mechanical strength and anti-acid pollution performance for the insulators.
5, All our insulators were type tested and design tested in accordance with IEC61109, maximum RIV is 100µV when tested at 1MHz and10% over nominal line ground voltage for indicated system voltage.
Applications:
1, Used in electrified railways
Competitive Advantage:
Advantage No. One
| 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. |
Advantage No. Two
