1.Application Scenarios
1. Electrical Distribution Systems
Used for busbar connections in distribution cabinets/switchgear or cable branch connections.
Serves as a grounding conductor (PE) via through-holes to connect grounding bars or equipment enclosures.
2. Mechanical Assembly
Acts as a conductive path or structural support in machinery (e.g., motors, gearboxes).
Through-hole design facilitates integration with bolts/rivets for unified assembly.
3. New Energy Sector
High-current cable connections in PV inverters, energy storage systems, or EV battery packs.
Flexible routing and protection for busbars in solar/wind energy applications.
4. Building Electrical Engineering
Cable management in indoor/outdoor cable trays for lighting and low-voltage systems.
Reliable grounding for emergency power circuits (e.g., fire alarm systems).
5. Railway Transportation
Cable harnessing and protection in train control cabinets or overhead contact line systems.
2.Core Features
1. Material & Conductivity
Made from high-purity electrolytic copper (≥99.9%, T2/T3 grade) with IACS 100% conductivity.
Surface treatments: Tin plating or antioxidation coating for enhanced durability and reduced contact resistance.
2. Structural Design
Through-Hole Configuration: Pre-configured standardized through-holes (e.g., M3–M10 threads) for bolt/rivet fixation.
Flexibility: Copper pipes can be bent without deformation, adapting to complex installation spaces.
3. Installation Flexibility
Supports multiple connection methods: crimping, welding, or bolted connections.
Compatibility with copper bars, cables, terminals, and other conductive components.
4. Protection & Safety
Optional insulation (e.g., PVC) for IP44/IP67 protection against dust/water.
Certified to international standards (UL/CUL, IEC).
