Description
Product Introduction
The JN15-24/31.5 Indoor High-Voltage Grounding Switch is our latest-developed safety device, designed to meet the strict requirements of GB1985-2004 and IEC62271-102:2002 standards. It is engineered for 24kV, 50/60Hz three-phase AC indoor power systems.
This grounding switch provides a reliable earthing path for maintenance, discharging residual voltage and preventing accidental re-energization. With its 31.5kA short-circuit closing capability, it protects other switchgear components from damage during faults. It can be integrated with various high-voltage switchgear cabinets or used independently for grounding protection during equipment maintenance.
Core Advantages
- Globally Certified Compliance: Fully compliant with both GB and IEC international standards, ensuring seamless integration into global power projects and easy acceptance by overseas clients.
- Advanced Compact Design: Optimized for limited indoor spaces, with a streamlined structure that simplifies installation and reduces footprint.
- High Fault Resilience: Rated for 31.5kA short-circuit closing, providing robust protection for your switchgear during fault conditions.
- Wide Environmental Adaptability: Operates reliably in extreme temperatures from -25°C to +40°C, with seismic resistance up to 8 degrees, suitable for challenging indoor environments.
- Low Maintenance & Durability: Simple mechanical structure with high-quality components ensures long service life and minimal upkeep, reducing lifecycle costs.
