GW4-40.5, GW4-40.5D Isolating Switch to unipolar type, with the three-link together into a three-pole unipolar conductive arm, the linkage of the isolating switch, the linkage rod from the left and right hand to the screw component, easy to adjust the three-phase synchronous, single-stage can also be used.
GW4-40.5 series isolation switch from the base, pillar insulator and conductive components, each pole has two ceramic columns were installed in both ends of the bearing pedestal base with cross-link connection, you can rotate the level. Knife made? ? By the copper conductive, the contact is that in the middle of two columns, pillars porcelain knife were fixed in the top.
