Flexible Copper Braided Electrical Connectors
Products Description
Flexible Copper Braided Electrical Connectors are constructed using high-purity copper wire-typically T2 grade or oxygen-free copper-which undergoes a precision braiding process to form the main conductive body. The two ends are subsequently connected to terminals via crimping, welding, or composite bonding processes, thereby creating a complete conductive assembly.
Its core structural features include:
A multi-strand braided filament structure that establishes a uniform conductive path;
A flexible and variable cross-section capable of accommodating different current ratings;
Customizable terminal configurations (including hole diameter, thickness, and plating);
Support for a choice between insulated sheathing or a bare copper structure.
This structural design not only optimises current distribution but also significantly enhances fatigue resistance.
Comprehensive Analysis of the Production Process
Copper Wire Refining and Annealing
Raw materials undergo multiple stages of continuous vacuum casting followed by multi-stage in-line annealing. This process eliminates internal stresses, ensuring the Copper power braid achieves optimal ductility.
01
High-Precision Braiding
Utilising imported CNC braiding machines, tension and braiding angles are monitored in real-time to ensure that the density deviation of each braided layer remains below 1%. The system supports single-layer, double-layer, and even multi-layer superimposed braiding configurations to meet diverse flexibility requirements.
02
Forming and Heat Treatment
Upon completion of braiding, a secondary low-temperature annealing process is performed to relieve work hardening. Simultaneously, specialised moulds are employed for precision shaping, guaranteeing that the Braided Tin Coated Copper Flexible Wire Connectors retains its original geometric accuracy throughout transportation and installation.
03
Terminal Processing
Three processing options are available: crimping, silver brazing, or friction welding. The welded joints undergo non-destructive X-ray inspection to ensure a 100% metallurgical bond at the interface, thereby eliminating any risk of cold joints or faulty connections.
04
Surface Treatment and Inspection
A closed-loop quality control system is established through the integration of fully automated plating lines, ultrasonic cleaning, and a salt spray testing laboratory. Every production batch undergoes rigorous verification of electrical performance, mechanical tensile strength, and bending fatigue life.
05
Superior Design Advantages: Centred on Engineering Pragmatism
Flexible Margin Design
Based on specific customer displacement requirements, we scientifically calculate braid density and length redundancy to ensure that the rated current-carrying capacity is maintained even under maximum deformation.
Customised Insulation Protection
We offer a choice of PVC heat-shrink tubing, silicone sleeving, or Teflon sheathing-solutions that not only feature high voltage withstand ratings but also possess excellent flame-retardant properties (UL94-V0 rated).
Compact Spatial Layout
For applications involving confined spaces within power distribution cabinets, we can design bent, stacked, or custom-shaped connection solutions to maximise space utilisation efficiency for Copper Stranded Flexible Connection.
Application Advantages: Covering Key Industrial Electrical Scenarios
| Power Transmission and Distribution | Flexible connections for the high- and low-voltage terminals of transformers; flexible transitions between busbars within switchgear; connections between circuit breakers and Braided Wire Flexible Copper; and grounding jumpers for gas-insulated switchgear. In these scenarios, flexible connections serve not only a conductive function but also act as a structural safeguard, ensuring the long-term, stable operation of the equipment. |
| Industrial Equipment | Rectifiers, electrolytic smelting equipment, industrial electric furnaces, welding equipment, and high-power frequency converters. These devices are characterised by extremely high current loads, significant heat generation, and frequent start-stop cycles. Thanks to their resistance to heat, vibration, and fatigue, braided flexible connectors perform exceptionally well under these demanding operating conditions. |
| New Energy and Transportation | Series and parallel connections between power battery modules; Flexible Copper Braided Busbar Connectors for energy storage systems; internal conductive bridges within photovoltaic inverters; and grounding systems for electric locomotives and subway trains. These applications impose particularly stringent requirements on connectors regarding vibration resistance, high-temperature tolerance, and long-term reliability. |
| Explosion-Proof and Special Environments | In underground coal mining equipment and explosion-proof chemical facilities, flexible connections eliminate the risk of friction-induced sparks-a potential hazard associated with rigid connections-making them an essential choice for ensuring safety and regulatory compliance. |
