Product DescriptionHigh-Performance Sealed Conductor Splice (GL/GT Series)Precision-engineered for oil-filled cable systems, our splice utilizes vacuum-brazed bimetal interfaces and nano-sealing technology to achieve zero-leakage performance under 2.5MPa hydraulic pressure. The core employs oxygen-free copper (C10200) conductor sleeves with electro-deposited 10μm silver plating, maintaining contact resistance ≤1.5μΩ while preventing galvanic corrosion. The multi-layered sealant system combines fluorosilicone gaskets and graphite-reinforced EPDM for permanent compression set <5% at 150°C.SpecificationMaterial Science SpecificationComponentAdvanced Material & ProcessConductor SleeveOFHC C10200 + 10μm electro-silver plating (Ra≤0.8μm)Pressure BarrierHot-isostatic-pressed 6061-T6 Al alloy (0.2% offset yield ≥280MPa)Primary SealTriple-layered fluorosilicone (FVMQ) with PTFE reinforcementCorrosion ShieldElectroless Ni-P coating (85μm, porosity <0.15 p/cm2)Critical Performance ParametersHydraulic Integrity: Zero leakage @ 2.5MPa/30min (ISO 1402 pressure cycle tested)Electrical Stability: Δ% after 500 thermal cycles (-40℃?125℃)Mechanical Strength: Shear resistance ≥22kN (ASTM B831 compliant)Chemical Resistance: Withstands transformer oil/ester fluids @150℃ for 20,000hEngineering ApplicationsSubstation Risers: Prevents dielectric fluid leakage in vertical cable runsOffshore Wind Links: Salt fog resistance >3000h (ISO 9227 C5-M class)Desert Solar Farms: UV stability >15 years (ISO 4892-3 Xenon Arc)Industrial Corridors: Resists acid gas permeationTransformer Terminations: Maintains oil viscosity stability (±5% @100℃)Sealing Technology InnovationRadial Compression System: 16-segment alloy jaw with 0.01mm concentricity toleranceThermal Compensation: Coefficient-matched bimetal stack (ΔL/L ≤0.001%/K)Anti-Migration Design: Molecular-sieved absorption layer traps micro-bubblesInspectionWe 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.
