As a professional manufacturer with extensive experience in electrical safety equipment, Jinhua Dika Electrical Equipment Co., Ltd. proudly presents our ASTA Certified 24kV Remote-Operated Earthing Switch. This switch is engineered to provide reliable and safe circuit isolation in high-voltage applications, ensuring operational safety and system integrity. Our commitment to quality, backed by a robust management system, allows us to deliver products that meet the stringent demands of global markets, from North America to Southeast Asia.
The core value of this earthing switch lies in its remote operation capability and ASTA certification, which guarantee performance under specified conditions. It is designed for personnel safety during maintenance, testing, or fault conditions by securely connecting the circuit to earth, thereby discharging any residual voltage. This critical function prevents accidental electrocution and equipment damage.
Key Features & Technical Specifications:
- ASTA Certification: Independently verified performance ensuring reliability and compliance with industry standards for earthing switches.
- Remote Operation: Allows safe switching from a control room or remote location, minimizing exposure to live parts for operators.
- High Voltage Rating: Rated for 24kV systems, suitable for a wide range of substation and industrial power distribution applications.
- Robust Construction: Built with durable materials and designed for long-term outdoor or indoor installation, resistant to environmental factors.
- Clear Position Indication: Features a visual indicator (often mechanical flag or colored display) to clearly show "Open" or "Earthed" status, enhancing safety.
- Lockout Facility: Provides a means to physically lock the switch in the earthed position to prevent unauthorized or accidental operation during work.
- Flexible Control Options: Can be integrated with local push-button controls or integrated into SCADA/remote monitoring systems for centralized operation.
- Easy Installation & Maintenance: Designed for straightforward mounting on panels or structures, with accessible parts for inspection.
