Description:
?
1, 110kV Composite Insulators used for high lands overhead transmission lines are welled designed to suit to the special environment in high lands like very strong UV rays and wind.
?
2, Dead end fittings are up to the requirements from the clients, usually we use ball, socket, tongue, clevis for suspension insulators with forged 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.
?
6, All the 110kV suspension or tension insulators are designed with one corona rings
?
?
Applications:
?
1, 110kV overhead transmission power lines in high lands.
?
2, 110kV substations high lands.

Competitive Advantages:
- - - -
? | ? | 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. |
