Product DescriptionHigh-Conductivity Bolted Copper-Aluminum Equipment Line ClampEngineered for critical power connections, our bolted copper equipment clamps utilize oxygen-free C11000 copper (ASTM B187) with 99.99% conductivity (IACS 101%) for minimal energy loss. The cold-forged body achieves 240 MPa tensile strength through grain structure optimization, while micro-arc oxidation (MAO) coating provides >1,000h salt-spray resistance per ASTM B117. Precision-machined contact surfaces employ helical groove design to increase conductive area by 40% versus standard clamps.SpecificationSpecificationCore Innovation:Material Science: C11000 copper with tellurium doping (CuTe) enhances ductility while maintaining 58 MS/m conductivitySurface Engineering: 8-12μm tin-plated layer (per ASTM B545) prevents galvanic corrosion at bimetal junctionsStructural Integrity: Finite element analysis-optimized bolt pockets distribute clamping force within ±5% varianceApplicationsSubstation Busbars: Ultra-low contact resistance (<5μΩ) for GIS systemsRenewable Interconnection: Zero-creep performance under 10,000 thermal cycles (-40°C to 125°C)Coastal Power Networks: Self-healing oxide layer resHeavy-Current Junctions: 2,500A continuous rating at 85°C ambientSeismic Zones: Vibration damping via Belleville washer stacksKey ConfigurationsComponentTechnical SpecificationsConductor CoreC11000 ETP Copper (ASTM B187)Surface TreatmentElectrodeposited Tin Layer (8-12μm)Conductivity≥58 MS/m (20°C)Mechanical Strength240 MPa Tensile / 120 MPa ShearCorrosion Resistance>1,000h Neutral Salt Spray (ASTM B117)Thermal Stability-50°C to +150°C (ΔR<3%)Torque ToleranceM16 Bolts: 65±5 N·m (SAE J1919)Engineering DataElectro-Thermal Modeling: Current density distribution verified via COMSOL Multiphysics?Contact Physics: 0.15-0.25 GPa interfacial pressure for oxide penetrationFatigue Life: >30,000 mechanical cycles per IEC 61238-1 Annex BInspectionWe do inspection for each batch of goods before shipment Company ProfileWuhan Hwanai Metal Casting Co., Ltd Wuhan Hwanai Metal Casting Co., Ltd. specializes in the production and export of power line hardware, with over 20 years of experience in the industry.
