Copper Grounding Ferrules – Precision Impact Extruded Connectors for Electrical Grounding
Price: US$ 12.40/kilogram
We are one of the leading manufacturers and exporters of Copper Grounding Ferrules from India. With over three decades of experience in non-ferrous metal forming, we specialize in producing precision-engineered Copper components using advanced impact extrusion technology. Our Copper Grounding Ferrules are designed for high-integrity grounding connections in power, telecom, industrial, and utility-grade electrical systems.
These ferrules are manufactured from high-conductivity ETP Grade Copper (C11000) using a single-stroke impact extrusion process, which ensures seamless construction, consistent wall thickness, and optimal current-carrying capacity. Our products are widely used in substation grounding, lightning protection, and earthing systems where low-resistance and long-term corrosion resistance are essential.
Product Overview Copper Grounding Ferrules are solid, one-piece connectors with a cylindrical body, made for inserting and crimping stranded copper conductors. The seamless design eliminates joint weaknesses and minimizes electrical resistance. The outer surface can be plain or tinned to meet corrosion resistance or environmental requirements.
Material Grades and Standards
- Material: Electrolytic Tough Pitch Copper (ETP), UNS C11000
- Standards: ASTM B187, IEC 61238-1, UL 486A/B (on request), RoHS compliant
- Finish Options: Plain, Electro-Tinned (Lead-Free)
Manufacturing Process: Impact Extrusion Our Copper grounding ferrules are made using cold impact extrusion, where a solid Copper slug is placed in a die and struck with a high-force punch. This results in:
- Seamless, burr-free cylindrical shape
- Dense and uniform grain structure
- Excellent dimensional accuracy
- High mechanical strength with no porosity
Machinery Used
- High-tonnage impact extrusion presses
- Precision billet cutting machines
- Automatic trimming & deburring
- Electro-tinning bath (RoHS-compliant)
- Optical inspection and laser engraving systems
Typical Applications
- Grounding conductors in switchgear and substations
- Lightning protection systems
- Earth mats and grid systems
- Solar grounding installations
- OEM and prefabricated electrical panel assemblies
Product Features and Benefits
- Seamless Design: No weld lines or seams means superior conductivity and mechanical reliability
- Low Resistance: Designed for minimal voltage drop and efficient fault current dissipation
Shrouded 1/0 Copper Grounding Ferrule with Short Threads (1.5in.)
- Short 1.5in. threads versus standard 2.0in.
- For use with 1/0 grounding cable
- Shrouded ferrules overlap onto the grounding cable jacket for stress relief to the terminal
- Two crimps secure the ferrule against the bare strands and one crimp applies on the jacket
- The ferrules install simply with a hydraulic crimping tool
- Complete illustrated installation instructions come with the ferrules and include a table for the crimping die sizes to use
