Component Specifications

Definition
The Cathode Plate Clamp is a critical component in electrolytic cells used for metal refining, particularly in copper, zinc, and nickel production. It provides mechanical fixation and electrical connection between the cathode plate and the cathode bar, ensuring stable current distribution and preventing plate movement during electrolysis. The clamp must maintain consistent pressure across the contact surface while resisting corrosion from acidic electrolytes.
Working Principle
The clamp operates on mechanical compression principles, using spring-loaded or hydraulic mechanisms to apply uniform pressure between the cathode plate and cathode bar. This creates both a secure physical connection and a low-resistance electrical pathway for current flow from the busbar system through the cathode plate into the electrolyte solution.
Materials
High-grade copper alloys (C11000, C10100) or aluminum alloys with corrosion-resistant coatings; insulating components made from PTFE, ceramic, or high-density polyethylene; spring elements from stainless steel (316L)

  • Clamping Force 2-5 kN
  • Contact Pressure 15-25 MPa
  • Current Capacity 5000-15000 A
  • Corrosion Resistance pH 1-3 acidic environments
