Flexible Copper Braided Connectors
Products Description
In modern electrical system design, conductive connections are not merely about "conduction," but also involve structural adaptability, electrical stability, and long-term reliability. Flat copper braided wires are a key component developed in this context. By densely braiding multiple strands of fine copper wire, a connection structure is formed that combines flexibility and high conductivity, ensuring stable conductivity even under complex operating conditions.
Compared to traditional rigid copper busbars or single-strand wires, flexible copper braided connectors possess stronger dynamic adaptability, effectively absorbing mechanical displacement, thermal expansion, and vibration shocks during equipment operation.
Materials Science: The high purity of T2 oxygen-free copper is fundamental to its conductivity
Material Advantages: The entire product line uses T2-grade high-purity oxygen-free copper, with a copper content of ≥99.95%.
Surface Treatment Variety:
Bare Copper: Economical and efficient, suitable for general indoor environments.
Tinned Copper: Effectively inhibits oxidation of copper in high-temperature and humid environments, improves solderability, and withstands salt spray tests for 48-168 hours or more for Tinned Copper Braid Earthing Tape.
Silver Plated: Provides top-tier conductivity for specialized engineering applications requiring high-frequency communication or ultra-low impedance.
Application Advantages: Deeply Rooted in Four High-Barrier Industrial Sectors
New Energy Vehicle High-Voltage Systems
In the connection between the battery pack and the distribution unit (PDU) and motor controller (MCU), flat braided wire, with its extreme three-dimensional flexibility, perfectly adapts to the severe dynamic bumps of the chassis suspension system and is easy to insert and run within the narrow battery pack wiring channels.
Ultra-High Voltage and Transmission Equipment
As the grounding conductor of transformer bushings and GIS (Gas Insulated Substations), braided wire can effectively absorb the huge mechanical impact force generated during equipment switching operations, preventing porcelain bushing breakage.
Rail Transit and Heavy Engineering Machinery
Between locomotive traction motors and converters, there is long-term exposure to strong random vibration and dust erosion. The "fully enclosed sheath + internal tin-plated mesh" structure of braided wire exhibits extremely high environmental tolerance.
New Energy Storage and Inverter Systems
Flat Copper Braid Flexible is widely used in photovoltaic inverters and energy storage PCS compartments as a flexible bridge between modules. Its excellent heat dissipation and penetration effectively reduce the risk of thermal runaway of high-power devices.
Detailed Display
| Weaving Microstructure | Under a microscope, each copper wire is visible in a regular spiral interweaving pattern, with uniformly distributed contact nodes between the wires, and no loose strands or skipped wires. This precise weaving topology is the microscopic basis for the Braided Connectors' flexibility, conductivity uniformity, and structural stability. |
| Terminal Crimping Interface | The sectionalized terminal crimping area shows a dense cold-welded bond between the copper wire and the terminal board, with no visible gaps or oxide inclusions. The continuous metal flow lines in the crimping area indicate ideal plastic flow and metallurgical bonding under high pressure. |
| Flat Cross-Section Uniformity | The thickness deviation of the rolled flat strip is controlled within ±0.1 mm, and the edges in the width direction are neat and burr-free. The copper wires in each layer within the cross-section are tightly and orderly arranged, without local bulges or depressions, ensuring uniform surface pressure distribution during bolt tightening. |
| Platinum Integrity | The surface of the Braided Wire Flexible Copper after tin or nickel plating exhibits a uniform metallic luster, and the plating completely covers the surface of all exposed copper wires, including the recessed areas at the braiding intersections. Salt spray testing has verified that the coating can effectively protect the long-term reliability of the copper substrate in harsh environments. |
