HCC213-216 Fixed Contact for Trolley: Reliable Electrical Connection Component
2025-07-21
The HCC213-216 fixed contaCt is a critical component designed for trolley systems in electrical switchgear, providing stable electrical conduction between stationary and moving trolley units in medium-voltage power distribution equipment.
Core Design & Material
Constructed with high-conductivity copper alloy (electrolytic copper with silver plating oPtions), the contact features a precision-machined surface to ensure tight mating with trolley moving contacts. Its robust structural design includes a curved contact face that minimizes contact resistance while accommodating minor alignment variations during trolley insertion/extraction, reducing wear from repeated mechanical operations.
Performance & Durability
- Electrical Conductivity: Low contact resistance (≤50μΩ) ensures efficient current transmission, with rated current handling up to 630A, suitable for standard medium-voltage trolley applications.
- Arc Resistance: The silver-plated surface (optional) enhances resistance to arcing during connection/disconnection, extending service life under frequent operation.
- Mechanical Strength: Withstands 10,000+ insertion/extraction cycles without significant deformation, maintaining stable contact pressure (15-25N) for consistent conduction.
Application Scope
Specifically engineered for trolley-type switchgear in:
- Indoor medium-voltage (10kV-35kV) distribution cabinets
- Power distribution stations and industrial switchgear systems
- Renewable energy grid connection equipment
- Trolley-mounted circuit breaker or fuse units
Operational Advantages
- Easy Installation: Standardized dimensions (compatible with common trolley rails) simplify integration into existing switchgear assemblies.
- Low Maintenance: Corrosion-resistant plating and wear-resistant material reduce the need for periodic cleaning or replacement.
- Safety in Operation: Ensures reliable contact even during slight trolley vibrations, preventing intermittent conduction that could cause overheating or equipment failure.
