    1, 110kV (132kV) composite polymer insulator are designed to suit to 110kV (132kV) transmission line s and 110kV (132kV) 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 110kV (132kV) composite high tension insulators are designed with one corona ring.


    1, 110kV (132kV) overhead transmission power lines.

    2, 110kV (132kV) substations.

    Competitive Advantage:

    1, Very good anti-pollution performance, no need to wash the insulators after the installation in lines.

    2, Very convenient installation because of its light weight and one whole piece compared with glass insulators and ceramic insulators.

    3, Excellent hydrophobicity characteristics can help to void flashover and guarantee the insulators with very good electric performance.

    Competitive Advantages compared with ceramic insulators :

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

    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
    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.
