    Product name: SHGV
    Listing Date:2017-08-25

    Type SHGV vacuum on-load tap changer is of combined structure, applicable to SF6 gas insulation regulating transformers, comprising two major parts: diverter switch and tap selector. Tap changer is laid in the transformer gas tank by means of its head flange and the diverter switch is in a separate gas compartment. It can be used at neutral point of star-connection for three-phase; singe-phase for any selectable winding connection; a combination of three units of single-phase for any selectable winding connection and any position voltage regulating.
