The conductive electrode arm is a new type of cross arm made of copper steel composite plate or aluminum steel composite plate, with a rectangular cross-section shape and internal water cooling. The electrode arm eliminates many insulation links between the water-cooled conductive copper tube, 2 electrode voltage clamp, and cross arm, greatly simplifying the cross arm structure in ultra-high power electric arc furnaces.
Light weight, good stiffness, low impedance, and long service life.
One end of the conductive cross arm is supported on a column, and the other end is used to clamp the electrode, which has a lifting function. The lightweight of the conductive cross arm means that the driving power required for the electrode column to perform lifting and adjustment movements is relatively reduced, and so on.
The hollow section and double-layer copper steel composite plate are adopted to greatly reduce the Skin effect, reduce the impedance and improve the electric heating efficiency;
As parts of electric furnace, the hollow cross-section box structure and internal water-cooled channel greatly enhance the strength of the cross arm, which is conducive to adjusting electrode movement without causing vibration and is conducive to arc stability;
The weight is lighter than traditional steel tube type cross arms, with small inertia, which is conducive to frequent electrode lifting and adjustment.
