Product Introduction
HDHC tinned copper busbar is an upgraded product of traditional copper busbars, which improves conductivity and mechanical strength through hard drawing technology. Combined with tin plating and integrated insulation design, it solves the performance bottleneck in high-power scenarios. It is a customized high current conductive component designed for high-end electrical scenarios such as new energy, electricity, and rail transit. It is made of high-purity hard copper as the substrate and is made through precision stamping, bending, and professional tin plating processes.
Product advantages
Ultimate electrical performance
HDHC tinned copper busbar resistance ≤ 0.00001 Ω, with extremely low resistance to minimize power loss, reduce voltage drop in the distribution system, and improve the overall operational efficiency of the electrical system. This stable low-resistance characteristic also effectively controls temperature rise during long-term high-current operation, extending service life and enhancing system safety.
Super strong mechanical performance
Busbar coating substrate has a hardness of 80~110HV and a tensile strength of 245-345MPa. It has high mechanical strength and can withstand mechanical stress and vibration in industrial environments. It is not easy to deform or crack, and is suitable for vibration scenarios such as new energy vehicles and rail transit.
Excellent environmental adaptability
The dual protection of tin plating layer and insulation layer enables the Tin plated copper busbar to have excellent corrosion resistance and oxidation resistance, and can operate stably for a long time in harsh environments such as humidity, acid and alkali, high and low temperatures (-45 ℃ to+150 ℃).
Customized process
Requirement Submission and Engineering Review
Upon the customer's submission of electrical parameters (voltage, current, environment), mechanical interface drawings, and certification requirements, our engineering team assesses the Busbar tinned copper's current-carrying capacity, temperature rise control, insulation coordination, and mold feasibility, then issues a technical proposal.
Free sample production
Once the technical solution is verified, we will offer 1-10 free samples (the exact quantity varies based on complexity). The Copper tinned busbar samples will adopt the same mold and process specifications as mass production. Every sample will undergo comprehensive performance testing covering resistance, insulation, and voltage withstand capabilities to ensure alignment with bulk product standards.
Customer testing and verification
We offer free samples (quantity based on project needs). The Tin plated copper bar adopts standardized mold and process specifications, ensuring stable performance. All samples undergo strict performance testing covering voltage withstand, current resistance, temperature control, etc., to meet international quality standards.
Batch Delivery
Once the customer approves and locks the mold, mass production commences. Standard orders ship in 7-10 days; for new stamping dies and tooling, sample lead time is 10-20 days. Rigorous quality checks are performed throughout production to guarantee consistent dimensions, plating thickness and performance for all units. Ensuring stable product quality.
