Product Introduction
Copper busbar conductive beams, also known as electrolytic cell conductive beams or anode and cathode conductive beams, are core conductive components in electrolysis systems that integrate high current transmission, electrode suspension, and structural load-bearing. They are divided into two main series: pure copper conductive beams and titanium-clad copper composite conductive beams, which are suitable for dry, low-corrosion environments and highly corrosive electrolyte conditions, respectively.
Pure copper conductive beams are made from high-purity T2 electrolytic copper, exhibiting excellent conductivity and high mechanical strength. Titanium-clad copper composite conductive beams utilize a highly conductive copper core and a corrosion-resistant pure titanium outer layer, manufactured through explosive bonding and hot-rolling diffusion processes to achieve metallurgical-grade atomic bonding. Installed on top or inside electrolytic cells, these products directly contact corrosive acid mist and electrolyte splashes. Unlike traditional pure copper beams, which suffer from rapid corrosion and frequent replacement, and steel-copper composite beams, which suffer from high resistance and energy consumption, these beams offer stable resistance and uniform current distribution under long-term high-current operation, significantly extending service life and ensuring stable electrolytic production. They are widely used in industrial applications such as hydrometallurgical electrowinning, chlor-alkali electrolysis, electrolytic copper foil production, and alkaline water electrolysis for hydrogen production.

Product Features and Applications
Product Advantages
Dual-series selection covers all working conditions : Two major product series are available: pure copper and titanium-clad copper composite. The pure copper version is cost-effective and has the best conductivity, making it suitable for dry and non-corrosive top power distribution scenarios. The titanium-clad copper composite version has strong corrosion resistance and an ultra-long lifespan, making it suitable for highly corrosive tank scenarios with electrolyte splashing and acid mist. The selection can be made flexibly according to the project conditions.
Large cross-section and high current carrying capacity, uniform current distribution: Supports customization of large cross-sections up to 300×120mm. A single beam can carry tens of thousands of amperes of current, which is suitable for the load requirements of large electrolytic cells and high-capacity electrowinning production lines. The beam has a uniform cross-section and dense material, and the current is evenly distributed along the length of the beam, which ensures the consistency of current in each electrode plate and improves the quality of electrolytic products.
FHigh rigidity structural design with excellent load-bearing capacity: solid rectangular structure or reinforced I-shaped structure, which has both high conductivity and high bending rigidity. All anode and cathode plates can be directly suspended under large span installation without the need for additional intermediate support structure, simplifying the internal design of electrolytic cell, reducing the cost of supporting installation and auxiliary materials, and avoiding current shunting loss caused by support components.
Metallurgical-grade composite interface, stable long-term operation: The composite model adopts explosive bonding + hot rolling diffusion process to achieve atomic-level metallurgical bonding of titanium and copper. The interface has no gaps and no additional contact resistance. Under high current carrying conditions, the pressure is reduced and the temperature rise is small. There is no delamination and the resistance does not increase during long-term operation. The overall energy saving effect is significant, effectively reducing the electricity cost of electrolytic production.
Full titanium layer sealed protection, better cost throughout the entire life cycle: The composite working area is fully covered with titanium layer, and the weld seam is sealed with titanium material, which completely isolates the corrosive media from contact with the copper core. The corrosion resistance is more than 10 times that of traditional pure copper beams. It greatly reduces the frequency of downtime for replacement, grinding and maintenance, improves the continuous operation capability of the electrolysis production line, and has significant advantages in comprehensive cost throughout the entire life cycle.
Application Areas
Hydrometallurgical industry: Electrode plates are directly suspended from the conductive beams of the anode and cathode of the electrowinning and electrolytic refining cells for non-ferrous metals such as copper, zinc, nickel, and cobalt.
Chlor-alkali chemical industry: ion-exchange membrane caustic soda electrolytic cells, sodium hypochlorite generator anode conductive beams, resistant to chlorine corrosion and suitable for continuous operation with high current.
In the electrolytic copper foil industry: the anode conductive beam and cathode roller conductive support beam of the foil production unit ensure uniform and stable current and improve the consistency of copper foil thickness.
Electrolysis of water for hydrogen production industry: Anode and cathode conductive beams and high-current busbars for alkaline electrolysis of water for hydrogen production cells, suitable for high-load conditions in green hydrogen projects.
Electroplating and PCB industries: Conductive beams and busbar beams on the hangers of large electroplating production lines ensure uniform plating on workpieces.
Environmental water treatment industry: Electrocatalytic oxidation wastewater treatment, conductive beams for heavy metal recovery electrolysis devices.
Production line upgrade and transformation: replacing severely corroded pure copper beams and poorly conductive steel-copper composite beams, achieving cost reduction and efficiency improvement without modifying the main equipment.

Professional Consultation Q&A
Q1: How should one choose between a pure copper conductive beam and a titanium-clad copper composite conductive beam?
A1: The selection is mainly based on the corrosion intensity of the operating conditions: For dry, non-corrosive applications such as top-mounted power distribution in tanks and indoor busbars, pure copper conductive beams are preferred due to their superior conductivity and lower cost. For highly corrosive applications involving installation inside tanks, contact with splashing electrolytes, and pervasive acid mist, titanium-clad copper composite conductive beams are preferred due to their strong corrosion resistance, long service life, and superior overall cost. We can provide targeted selection advice based on your specific site conditions.
Q2: Can the electrode mounting positions on the conductive beam be customized according to our tank spacing?
A2: Absolutely. We support precise customization of electrode mounting hole spacing, lug structure, and positioning slots, perfectly matching the existing electrode plate spacing and hanging method of electrolytic cells. The finished product can be directly installed and hung on the electrode plates without the need for on-site secondary drilling, ensuring installation accuracy and reliable conductive contact.
Q3: Will surface oxidation of the conductive beam affect its conductivity after long-term use?
A3: Oxidation on the surface of pure copper beams can cause a slight increase in contact resistance, which can be restored by periodically polishing the contact surface. The titanium oxide film on titanium-clad copper composite beams is dense and stable, and will not continue to thicken, thus having no impact on conductivity. Our products are designed with sufficient conductivity margin, ensuring stable and reliable performance during normal use.
