Custom Shaped Pure Copper Connecting Bar – Process & Quality Assurance Statement
Our custom shaped pure copper connecting bars are designed as flexible, high-performance alternatives to traditional braided links, offering superior conductivity and custom geometry for seamless integration in modern switchgear assemblies.
Key process features
Manufacturing combines precision forming with strict material control to ensure reliable electrical and mechanical performance:
●Material Preparation: High-purity copper bars are selected and cut to length, with composition verified for maximum conductivity.
●Hot/Cold Forming: Bars are heated where necessary and precisely bent, twisted, or pressed into the required custom shape using specialized tooling.
●Stress Relieving: Controlled annealing removes forming stresses while preserving conductivity and ductility.
●Surface Treatment: Optional tin plating or polishing applied for enhanced corrosion protection and contact performance.
●Hole Drilling & Finishing: Precision punching adds mounting holes; edges are deburred for safe handling.
●Dimensional Verification: Each piece is checked against customer drawings for exact fit.
●Protective Packaging: Bars are individually wrapped and securely packed to maintain shape and surface quality during shipping.
Quality control system
● Complete traceability from copper lot to finished shaped bar
● Test reports including conductivity, dimensional accuracy, and bend testing provided with every order
● Sample retention ≥3 years for third-party confirmation (SGS, BV, TÜV, etc.)
● 100% inspection of essential parameters:
• Chemical purity and conductivity (>100% IACS typical)
• Dimensional and shape accuracy (3D CMM; typical tolerance ±0.5mm)
• Mechanical properties (bend and tensile testing on samples)
• Surface quality and plating uniformity (where applicable)
• Visual inspection for defects or deformation
● Internal standards exceed ASTM B187 requirements. Typical C11000 shaped properties: Excellent current-carrying capacity, Superior flexibility without fatigue cracking, Proven reliability in dynamic switchgear environments.
● ISO 9001:2015 certified operations ensure every custom shaped pure copper connecting bar delivers the precise fit, conductivity, and durability your switchgear projects demand.
