Product Introduction
Copper nickel plated fuse base serves as a highly reliable industrial-grade core component dedicated to NH series knife fuses. As a key part in low-voltage power distribution systems, it integrates three essential functions: electrical conduction, mechanical fixing, and fault isolation. Constructed with high-purity electrolytic copper as the main conductive body, its performance is further enhanced by professional nickel plating surface treatment. Well-suited for heavy-duty industrial applications and harsh operating environments, it works reliably with NH fuses to form a complete protection mechanism against overload and short circuits. It has become a preferred choice for global engineering procurement in industrial power distribution, new energy systems, heavy machinery, and other key fields.
Product advantages
Conductive Advantages
The purple copper material ensures extremely low resistance, significantly improving the efficiency of current transmission. This feature directly reduces the heat generation and energy loss caused by excessive resistance, effectively improving the overall energy efficiency of the electrical system and helping users reduce long-term operating costs.
01
Reliability advantages
The sturdy structural design enables the Copper nickel plated fuse base to adapt to harsh working conditions such as vibration and impact, ensuring stable operation in complex environments. A stable electrical connection ensures that the contact resistance remains at a low level for a long time, effectively reducing the risk of electrical accidents caused by fuse holder failures.
02
Maintenance Convenience Advantage
The simple opening and closing structure design of Fuse copper holders allows for easy installation and replacement of fuses without the need for additional tools. The upper cover is equipped with a clear identification area, which can quickly identify the rated parameters, thereby reducing maintenance costs and system downtime.
03
Advantages of Service Life
High quality copper material combined with nickel plating process endows Fuse copper bases with excellent corrosion resistance and wear resistance, significantly extending their service life. Reducing the frequency of replacement means that the total lifecycle cost can be reduced, and the mechanical lifespan of 5000 times fully meets the reliability requirements for long-term use.
04
Surface Treatment: Performance Enhancement of Nickel Plating Process
Super strong anti-corrosion and anti-oxidation
The nickel plating layer is dense and uniform, effectively isolating copper from contact with external moisture, salt spray, and corrosive environments, preventing copper oxidation, blackening, and rusting, greatly extending the service life of Fuse copper knife, especially suitable for complex working conditions such as new energy, petrochemicals, and outdoor environments.
Further reduce contact resistance
optimize the smoothness of the conductive contact surface of the coating, reduce contact resistance fluctuations, ensure more efficient current transmission, lower heat generation, and improve the electrical performance stability of Copper holders for knife type NH fuse links.
Enhanced wear resistance
The hardness of the nickel plating layer is much higher than that of pure copper, which can withstand the wear caused by frequent insertion and removal, opening and closing, ensuring that the mechanical life of the Copper holder for knife type fuses is ≥ 5000 opening and closing cycles, and can still maintain good contact under frequent maintenance scenarios.
The entire process of core production technology
Raw material selection and incoming inspection: High-purity copper is selected as the conductive material, combined with high-temperature resistant insulating ceramics/engineering plastics as the substrate. All raw materials undergo comprehensive testing for material, conductivity, insulation performance, etc. before entering the factory, and a traceability system is established to ensure the quality of Copper knife for NH fuse from the source.
Precision stamping forming: Using high-speed precision stamping equipment and customized molds, copper core components such as fuse clips, conductive seats, and contact blades are stamped and formed in one go. The size tolerance of the Copper knife set for NH fuse is strictly controlled, and 100% critical dimensions are detected to ensure precise fit with the fuse blade and eliminate the hidden danger of poor contact.
CNC bending forming: By using high-precision CNC equipment to achieve precise bending of copper parts, forming structures such as U-shaped clamps and contact springs, ensuring uniform clamping force and smooth opening and closing; After bending, stress relief treatment is carried out to avoid long-term deformation and ensure the mechanical life of the Copper knives for NH fuse meets the standard.
Fully automatic nickel plating process: Adopting a fully automatic continuous nickel plating production line, strictly controlling the entire electroplating process to ensure uniform coating and strong adhesion; After plating, salt spray and coating thickness testing are completed to form a dense anti-corrosion layer, improve the weather resistance and wear resistance of Red copper knife for NH fuse, and solve the pain points of bare copper oxidation.
Precise assembly of components: Accurately assemble nickel plated copper parts, ceramic bodies, insulation bases, fasteners and other components, and synchronously detect contact resistance (<50 μ Ω), insertion and extraction force, insulation withstand voltage, to ensure that the structure is firm, the contact is tight, and the electrical and mechanical performance meets both standards.
Comprehensive performance testing: The finished Copper nickel coated fuse base has undergone 100% inspection for appearance, size, contact resistance, voltage resistance, and other aspects. The mechanical lifespan has been verified through sampling (≥ 5000 opening and closing cycles), and environmental compliance tests such as RoHS and REACH have been completed. All non-conforming products have been removed to ensure delivery quality.
Cleaning, packaging, and storage: After ultrasonic cleaning to remove surface impurities from the Copper nickel plated fuse base, it is packaged in export grade moisture-proof and anti-collision packaging. After passing the inspection, it is stored and retained for testing reports, suitable for international logistics transportation, and easy for buyers to trace.
