GRL knows that in modern electrical equipment, there is a strict demand for connection solutions with high current carrying capacity, excellent flexibility and long-lasting reliability. Therefore, we focus on providing high-performance stranded wire soft connections. With its unique multi-strand stranded structure, it is ideal for you to deal with vibration, thermal expansion and cold contraction, and complex spatial wiring challenges. GRL’s twisted wire soft connections are a powerful supplement to traditional cables and hard busbars, providing safe and efficient power transmission solutions for various high-current and highly flexible application scenarios.

Kinlaire’s stranded wire soft connections are made up of stranded strands or bundles of high-purity copper wire (or tin-plated copper wire), and the connectors are usually fixed at both ends by processes such as crimping, soldering or friction welding. This unique stranded structure gives the product unparalleled flexibility, excellent electrical conductivity and excellent mechanical strength, making it outstanding in industrial, power and new energy applications that need to withstand frequent vibrations, displacements or require compact bending radii.

Our twisted wire soft connections have the following distinctive characteristics:

Excellent flexibility and plasticity: It is made of stranded strands of thin copper wire. It has extremely high flexibility and can withstand frequent bending, torsion and vibration. This makes it ideal for complex wiring in tight spaces or connecting moving parts such as robotic arms and electric vehicle battery modules.

High current-carrying capacity and low resistance: High-purity oxygen-free copper wire is used and the stranding process is optimized to ensure extremely low resistance and efficient current transmission capabilities, minimizing energy loss and temperature rise at connection points.

Excellent heat dissipation performance: The multi-stranded structure increases the surface area of the conductor, which is conducive to rapid heat dissipation, improves the continuous current carrying capacity of the product, and extends the service life.

Excellent vibration and fatigue resistance: The flexible design can effectively absorb mechanical vibration and displacement stress during equipment operation, significantly reduce the risk of fatigue fracture at connection points, and improve the long-term reliability of the system.

Convenient installation and firm connection: Prefabricated or customizable connection terminals at both ends ensure convenience, efficiency and firmness of connection with equipment and simplify the on-site installation process.

Diversified customized services: GRL can provide customized stranded wire soft connection products with different cross-sectional areas, lengths, diameters, terminal types, surface treatments (such as tin plating, nickel plating) and insulating materials according to customers ‘specific needs.

The main differences lie in the structure and application focus:

kết nối mềm dây xoắn: Multiple strands of thin copper wire are twisted together in a spiral shape to form a circular or quasi-circular cross-section similar to a cable. it generally hasBetter flexibility, more uniform electrical conductivity, and performs better when subjected to torsional and bending stresses. Suitable for applications requiring higher currents, higher mechanical strength and more complex bending.
Dây bện kết nối mềm: It is made of flat weaving of multiple bundles of copper wire, usually in a flat strip shape. It is extremely flexible in the width direction and is suitable for your needsUltra-flat structure, larger cooling areaand the application of bending in a single plane.

When choosing, you need to consider:Current level required, installation space, flexibility requirements (especially in bending direction), vibration level, and cost budget。Đội ngũ kỹ sư của GRL có thể đưa ra lời khuyên chuyên nghiệp dựa trên nhu cầu dự án cụ thể của bạn.

GRL’s stranded wire soft connections are widely used, mainly including:

new energy field: Internal connections of electric vehicle battery packs, chargers, energy storage systems, wind turbines, solar inverters, etc.
rail transit: Electrical connections, grounding systems and parts of locomotives and subway vehicles that need to absorb vibration caused by vehicle movement.
Industrial automation and robots: Motion control components, robotic arms, flexible power transmission and signal connections on production lines.
power equipment: Flexible connection and grounding inside distribution cabinets, switchgear, transformers, generators, circuit breakers, and isolating switches.
data center: Flexible power connections inside the server cabinet and connection points that need to eliminate thermal expansion and cold contraction stresses.

GRL offers a variety of reliable terminal connection methods to meet different needs:

Crimping: The most common method is to tightly press the copper sleeve or custom terminal with the stranded wire through a special mold to form a strong mechanical and electrical connection. Cost-effective and quick installation.
Brazing: Use filler metal (such as solder) to connect the stranded wire to the terminal at high temperatures to form an extremely low-resistance, high-strength connection, suitable for applications with extremely high performance requirements.
Friction Welding: Friction heat is generated by rotation and pressure, which combines the stranded wire and the terminal material at the molecular level. The connection quality is high, there is no flux residue, and is environmentally friendly and efficient.

The method chosen depends on the specific current level, mechanical strength requirements, environmental conditions and cost considerations.

Selecting the appropriate cross-sectional area of the twisted wire soft connection requires comprehensive consideration of the following key factors:

dòng điện làm việc định mức: This is the main determining factor, ensuring that the soft connection can safely and continuously carry the maximum operating current, leaving a certain margin.
Giới hạn tăng nhiệt độ: Under the maximum current, the temperature rise of the soft connection should be controlled within the maximum allowable working temperature range to avoid overheating and damage.
nhiệt độ môi trường xung quanh: Nhiệt độ môi trường xung quanh cao hơn sẽ làm giảm khả năng mang dòng điện và yêu cầu tăng diện tích mặt cắt tương ứng.
Yêu cầu giảm điện áp: Trong một số ứng dụng nhạy cảm với hiện tượng sụt áp, cần chọn các sản phẩm có diện tích mặt cắt lớn hơn để giảm điện trở.
Installation space and bending radius: Ensure that the product with the selected cross-sectional area can adapt to the actual installation space and the required minimum bending radius.
