Tin-plated grounding copper braided wire is a flexible conductive connection made by weaving multiple strands of thin copper wire in a warp and weft manner.
product Overview
Flexible copper braided wire is an indispensable flexible conductor in modern electrical connection and grounding systems. It is made of precision weaving of multiple strands of high-purity bare copper wire or tin-plated copper wire and has excellent flexibility, electrical conductivity and mechanical strength. andTin-plated grounded copper braided wireOn the basis of flexible copper braided wire, the copper wire is uniformly tinned, which greatly improves the oxidation resistance and corrosion resistance of the product, so that it can still maintain excellent conductivity in high-humidity, dusty or corrosive environments. Stability makes it an ideal grounding and flexible connection solution.
As a core component in the fields of electrical power, new energy, rail transit and industrial automation, tin-plated and grounded copper braided wire can effectively solve the connection rigidity caused by vibration, displacement, thermal expansion and cold contraction or installation errors during operation of equipment., ensuring efficient, safe and stable current transmission.
Core technologies: selected materials, precision weaving and excellent tin plating process
Our flexible copper braided wires, especially tin-plated and grounded products, bring together a number of advanced technologies designed to provide industry-leading performance and reliability:
- High-quality copper conductor: Using T2 or higher purity copper wire as raw material, and the copper content is usually above 99.9%, ensuring the low resistivity and high conductivity of the product. Copper’s excellent electrical conductivity is the cornerstone of efficient current transmission.
- Multi-strand precision braided structure: The product is made of multiple strands of fine copper wire (usually 0.05mm to 0.20mm) accurately woven according to specific rules (such as cross-weaving). This structure gives copper braided wire unparalleled flexibility, allowing it to easily bend, twist, and adapt to a variety of complex and dynamic installation environments. At the same time, the multi-stranded wire design also improves the uniformity of current distribution and heat dissipation efficiency.
- Advanced tin plating process: This is the core advantage of tin-plated grounded copper braided wire. Before or after braiding, uniformly electro-tinned the copper wire or braid. Tin layers have the following significant advantages:
- Super antioxidant property: Tin is not easy to oxidize in air and can form a stable passivation film, effectively protecting the copper inside from oxidation caused by air and moisture, thereby maintaining excellent electrical conductivity for a long time.
- Excellent corrosion resistance: Tin has good corrosion resistance to a variety of acid, alkali and salt spray environments, significantly extending the service life of the product under harsh working conditions such as humidity, chemical, and ocean.
- reducing contact resistance: Tin plating helps reduce the contact resistance of the connection terminal, ensures smoother flow of current and reduces heat generation and energy loss.
- Improve solderability: Tin-plated surfaces make it easier to solder for reliable connections to terminals or other components.
- Prevent electrochemical corrosion: In multi-metal contact grounding systems, tin plating reduces the potential difference between different metals and reduces the risk of electrochemical corrosion.
