Characteristics and ordering specifications of conductive cross arm products

Product features:
1. The product adopts copper steel composite plate welding to form an electrode cross arm, where the copper layer is used for conductivity and the steel layer is used to support various mechanical forces.
2. There is a water interlayer inside the electrode arm frame, which is cooled by water and can withstand the burning of the electric furnace water flame.
3. The electrode clamping adopts a butterfly spring, which drives the clamp to hold the electrode tightly. It is released pneumatically or hydraulically, with a high clamping force and reliable electrode clamping.
4. The electrode clamp adopts chromium copper alloy or copper steel composite plate, and the internal water cooling has a long service life.

Used for steelmaking electric arc furnaces, ladle refining furnaces, ferroalloy refining furnaces, etc., with electrode diameters of ¥ 300mm - ¥ 600mm, current of 7.7KA-70KA, and a total of 9 specifications.
