Description
Product Overview
The JN15-12 Indoor High-Voltage Earthing Switch is a core protection device designed specifically for AC 50/60Hz power systems with rated voltage up to 12kV. Its performance fully complies with the international standard IEC 129 . It can be seamlessly integrated with mainstream high-voltage switchgear from both domestic and international brands, serving as a critical component for ensuring maintenance safety in power systems.
During the maintenance of high-voltage equipment or lines, this switch quickly establishes a reliable earthing circuit to safely discharge residual charges and sudden fault currents to the ground. This fundamentally eliminates the risk of electric shock for maintenance personnel and prevents equipment damage caused by induced voltage or accidental re-energization. Its compact, modular design not only adapts to the installation requirements of different cabinet types, but also boasts excellent mechanical lifespan and electrical stability. It can withstand frequent operations and short-circuit impacts, providing long-term, stable earthing protection for scenarios such as distribution rooms, prefabricated substations, and industrial power distribution systems.
Core Features
- High Reliability Design: Epoxy resin insulation pillars provide excellent insulation performance and mechanical strength, enabling it to withstand frequent operations.
- Stable Earthing Performance: The copper conductive rod and flexible connection structure achieve low-impedance earthing, ensuring rapid discharge of fault currents.
- Strong Compatibility: Standardized installation interfaces allow seamless integration with mainstream domestic and international high-voltage switchgear brands.
- Comprehensive Safety Protection: Equipped with reliable open/close position indicators and an interlock mechanism to prevent misoperation.

Application Scenarios
- Earthing protection for 10kV/12kV indoor high-voltage switchgear
- Maintenance earthing for prefabricated substations and distribution rooms
- Earthing protection for industrial power distribution systems and new energy power stations
- Earthing circuit construction in power engineering renovation projects
Installation & Maintenance
- Installation Requirements: Must be installed vertically inside the switchgear. Ensure the earthing circuit is securely connected, with an earthing resistance ≤1Ω.
- Daily Maintenance: Regularly check the cleanliness of insulation pillars and the tightness of conductive contact points.
- Operation Notes: Opening and closing operations can only be performed after the equipment is de-energized. Confirm the line is voltage-free before operation.
