Frequently Asked Questions
How much cost savings can SUNKEAN’s copper-to-aluminum connection solution deliver?
Compared to a full-copper system, this solution reduces costs by up to 58%. In a 1 GW PV power plant project, the savings can exceed USD 2,750,000.
How is SUNKEAN's copper-to-aluminum conversion harness designed to ensure stability and safety?
The harness uses a "copper–aluminum–copper" structure: copper conductors on both ends with an aluminum conductor in the middle, plus a plastic connector housing. It supports high currents and allows quick on-site crimping at the aluminum end for simplified installation.
What welding process is used for the copper-to-aluminum joint, and how reliable is it?
The connection adopts friction welding (solid-state bonding), which operates at low temperatures to minimize thermal damage to the cable. Over 25 years, conductivity degradation is less than 0.5%. The tensile strength is verified through pull and impact testing.
How does the copper-to-aluminum connector maintain corrosion resistance in harsh environments?
The joint surface is protected by a three-layer gradient structure: diffusion layer, chemical nickel plating layer, and hot-dipped tin anti-oxidation layer. An electroplating hole design ensures uniform coating. In a 96-hour 5% salt spray test, no corrosion occurred in the contact area.
