On the afternoon of May 9, 2025, the Intersolar 2025 was successfully concluded in Munich, Germany. During the exhibition, SUNKEAN's new Conversion Connector SK-TC made its global debut at booth A4.117. This new product and other products on display, such as fireproof, waterproof, and rodent-proof high-performance cables and conventional medium and low voltage cables, have jointly broken through the turbulent pattern of the international energy market and attracted much attention from upstream and downstream companies in the photovoltaic industry on site.

The new copper to aluminum conversion connector presented by SUNKEAN this time is based on the concept of "aluminum replacing copper". After more than a year of testing and research and development, it has fully utilized the advantages of aluminum materials such as low cost and light weight, and is committed to injecting new vitality into the long-term development of the photovoltaic industry. The development of aluminum materials in the fields of automobiles and electricity has a long history. For example, the aluminum wire high-voltage wiring harness of Tesla and the automotive wiring harness of Furukawa Electric aluminum alloy materials balance the overall conductivity, mechanical strength and flexibility.

As for the photovoltaic market, Japan has been facing a social problem in recent years, with a surge in cable thefts due to the high copper prices. SUNKEAN has taken the lead in responding by controlling the market development trend. As the world's first professional energy cable manufacturer to obtain the S-JET Japanese standard aluminum wire certification, it has accumulated rich practical experience in the direction of "aluminum replacing copper". The complete copper-aluminum connection solution including the copper-aluminum conversion connector launched this time is composed of three parts: copper conductor cable, aluminum conductor cable and copper to aluminum conversion connector, which overcomes many problems in copper-aluminum conversion, such as electrochemical corrosion, thermal expansion, creep reaction and crimping process.

SUNKEAN's copper to aluminum wiring harness has complete certifications, has passed TÜV Rheinland certification, and meets RoHS and Reach certification requirements. In addition, the newly upgraded welding process and interior cabin design can ensure that it avoids brittle fracture during actual use and achieves fast "blind plugging" within 30 seconds. In addition, the special matching aluminum terminal crimping tools and wrenches developed by SUNKEAN will also escort the ease of operation of the solution.

At the upcoming Shanghai SNEC in June, SUNKEAN will further enhance the copper to aluminum conversion connector and bring you a comprehensive analysis of the copper-aluminum conversion solution in the form of a press conference. We look forward to working with you to connect the world with faster and more efficient connection solutions and promote the development of green energy.
