Rack Busbars are designed for OCP ORv3 systems and high-density AI data centers, delivering high-current DC power distribution from 425A to 2900A. Featuring a laminated structure and blind-mate connections, they simplify installation, reduce cabling, and improve airflow. Custom designs are available for different rack configurations and power requirements.
Power Busbars are designed for OCP Power Shelves, BBU/CBU shelves, and rack-mounted PCS systems, delivering high-current, low-loss power distribution. Custom dimensions, copper thicknesses, configurations, and mounting options are tailored to specific equipment requirements, enabling precise integration into compact 1U layouts and high-density power systems.
As AI computing drives higher rack power density, OCP liquid-cooled racks provide efficient thermal management for high-power data centers. Direct liquid-cooled busbars further enhance heat dissipation at the busbar and shelf levels, enabling higher-current power distribution and supporting high-density rack architectures.
Custom copper busbar with epoxy powder-coated insulation features a thin dielectric layer with excellent heat dissipation, high dielectric strength, and strong resistance to high temperatures and electrical stress. Precision 3D forming and punching ensure accurate fit and easy integration into standardized assemblies. Designed for high-current applications, copper busbar offers reliable conductivity, good creep resistance, long service life, and low maintenance. Widely used in EV battery packs, energy storage systems (ESS), and power distribution systems for safe and efficient electrical connections.
Overmolded copper busbar, with PA66+GF30 engineering plastic overmolded directly onto the copper conductor in a single integrated process. The insulation layer is tightly bonded to the conductor, eliminating delamination or detachment risk. Features high mechanical strength, an operating temperature range of -40 °C to 120 °C (max. 150 °C), and excellent formability. Over 50% higher flexural strength than conventional designs ensures reliable electrical and mechanical stability under high-temperature and high-vibration conditions.
Battery busbars combine heat-resistant copper conductors with ceramic-based insulation to ensure dielectric strength, high-temperature endurance, and mechanical durability. Automated winding delivers uniform coverage and adhesion, enhancing thermal management and current-carrying reliability. Ideal for high-voltage EV battery pack interconnections.
Battery power copper bus bars are made of copper foil thickness from 0.1 to 1mm. They are produced by process of welding, stamping, plating, forming, insulation and so on. The plating can be tin and nickel. The insulation can be pvc dipping and PE heat shrink tubing. Because of it's feature of good conductivity, flexible, easy to install and space saving, flexible busbars are widely used in electric vehicle battery pack, new energy power distribution, UPS, Charging pile etc.

Flexible copper busbars are manufactured from multiple layers of thin electrolytic copper foil and feature precision machining, including surface polishing, edge rounding, precision punching, and deburring. Nickel strips are applied to enhance connection reliability and service life, while heat-shrink insulation provides electrical protection and resistance to mechanical damage and corrosion. Rounded edges help prevent damage to surrounding insulation during installation. Fully customisable to meet specific application requirements.
