Description:


1, ±500kV DC suspension tension insulators are widely used in overhead transmission lines and substations.


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 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.


6, All the ±500kV DC suspension or tension insulators are designed with two corona rings.


Applications:


1, ±500kV DC EHV overhead transmission power lines.

2, ±500kV DC EHV substations


Competitive Advantage:


The advantages of polymer/composite insulators over ceramic/porcelain insulators
General comparison
FactorCeramic/porcelain insulatorsPolymer/composite insulators
Weight

Heavy weight- For example

400kV - about 140kgs

90% lighter than them but with same mechanical strength

400kV -- Around 15kgs

FragilityHighly fragility to shock and vibrationNo fragility to shock and vibration
Packing and transportationRisky and very costlyEasy and economical
InstallationRisky expensive and more labor requiredVery easy and economical
HandlingDifficultEasy
Maintenance costVery expensiveLow
VandalismMore susceptibleHighly resistant
Breakages and secondary damageHighly fragile- 10-15% breakages are reported during transportation storage and installationFlexible and therefore highly resistant to breakages
Technical comparison
Mechanical failureReduction in mechanical strength and separation during to pings getting erodedJust with single piece, so no such kind of problem
Resistance to flashover and puncturesLowHigh
Anti tracking and erosion resistanceVery low- poor tracking resistanceExcellent tracking resistance avoids erosion or tracking of the housing material
Dielectric strengthLower than polymerExcellent insulation performance
Contamination and pollutionHighly effectedNot effected and has much longer life
HydrophobicityNo hydrophobicity, ceramic surface forms water films on the surface making easy path leading to more flashoverVery excellent hydrophobicity
Self cleaning qualityNo, dirty sand salt snow etc are easily attractedYes, due to hydrophobicity recovery characteristics
Tension strengthGoodBetter during crimping technology
MaintenanceNeeds maintenance like cleaning washing and greasingNot required at all
SafetyAre easy to explosion and breakages due to high fragile properties and stone throwing or gun shootingProvide very high level of safety superior flexibility and strength. not easy to break due to stone throwing or gun shooting.
