SUNKEAN JAPAN's Aluminum Cable Solutions

In recent years, as the demand for renewable energy projects, especially solar power plants, has surged, the use of copper cables has faced challenges. Issues such as theft and rising copper prices have made aluminum cables an attractive alternative. Known for their lightweight and cost-effective properties, aluminum cables not only reduce material and transportation expenses but also ease the installation burden. Thus, the adoption of aluminum cables as a substitute for copper is rapidly expanding.

However, the differing physical and chemical properties of copper and aluminum present challenges in achieving stable connections. To overcome the risks of electrochemical corrosion and increased contact resistance due to oxide films, a comprehensive connection solution is essential.

1. SUNKEAN's Aluminum Cable Connection Solutions

To ensure a reliable connection between aluminum cables and devices, SUNKEAN provides two solutions that address the challenges of electrochemical corrosion:

1.1 SUNKEAN Aluminum Cable × SUNKEAN Bimetal Terminal

This solution employs friction welding technology to create a strong bond between aluminum conductors and copper terminals. The terminal surfaces are treated with tin plating, and a compound is used internally, providing both ease of installation and reliability.

1.2 SUNKEAN Aluminum Cable × Panduit Bimetal Terminal

The Panduit bimetal terminal features a hybrid structure combining copper and aluminum. Through friction welding technology, both materials are securely joined, allowing for direct attachment to copper breakers and terminal blocks. SUNKEAN collaborated with Panduit to conduct compatibility tests on SUNKEAN's aluminum cables with Panduit's bimetal terminals. Following thorough verification, SUNKEAN has issued a compatibility certification.

2. SUNKEAN's Linear Connection Solutions

Direct connections between copper and aluminum conductors are complex and typically require an intermediary connection tube. Therefore, strict installation requirements must be adhered to. SUNKEAN has partnered with TE Connectivity to implement a mechanical conductor connection tube.

Features of TE Mechanical Conductor Connection Tube

• - Compatibility: Suitable for both copper and aluminum conductors, allowing diverse connecting options.
• - Crimping Not Required: The torque-type bolt structure eliminates the need for crimping or compression tools, and standard impact wrenches or spanners can be used for installation.
• - Conformity with Standards: Complies with major standards including JCAA K1001 and JIS C2810.
• - International Standards Compliance: Passed IEC 61238-1 Class A tests and conforms to IEC 61238 and GB 9327 standards.

SUNKEAN provides two solution options adaptable to site environments and installation conditions:

2.1 SUNKEAN Aluminum Cable × TE Mechanical Conductor Connection Tube + Heat Shrink Tube

This method offers reliable insulation and waterproofing. The heat shrink tube tightly adheres to the connection point when heated, showcasing excellent sealing capabilities, making it highly weather-resistant for long-term outdoor use. However, this technique requires heating equipment to be utilized during the installation, emphasizing safety and environmental considerations at the work site.

2.2 SUNKEAN Aluminum Cable × TE Mechanical Conductor Connection Tube + GelWrap

GelWrap, a protective waterproofing material, comes in a half-split wrap type, eliminating the worry of forgetting to feed it in before connecting conductors. This method features fewer components and only requires the two-step process of connection and wrapping, making it easy to confirm when installation is complete. Furthermore, it does not require tools, and installation is possible even in environments lacking power supply.

Summary

The adoption of aluminum cables is becoming an inevitable trend in the renewable energy sector, driven by cost reduction and theft prevention. SUNKEAN offers a comprehensive solution that covers everything from the cables themselves to end-processing and copper-aluminum connections, ensuring safe and efficient options for its customers. Moving forward, SUNKEAN is committed to advancing technological innovations and contributing to the growth of the solar energy and renewable energy industries worldwide.
