Grounding Switch Solutions for Safe Power Systems | Degatech Electric



Introduction
Grounding switches are vital components in medium- and high-voltage electrical systems, providing a safe path for residual or fault currents during maintenance and emergency isolation. They protect personnel, equipment, and the network from unexpected electrical hazards. Degatech Electric Co., Ltd. (https://chinadegatech.com/) offers a comprehensive line of grounding switches designed to meet the highest safety standards and operational requirements.

As electrical networks grow more complex, ensuring reliable grounding during maintenance or fault isolation becomes increasingly critical. Degatech grounding switches provide visible, mechanically secure grounding that enhances operational safety and system reliability.

What is a Grounding Switch?
A grounding switch, also known as an earthing switch, is an electrical device used to connect isolated parts of a system to the earth, safely dissipating residual electrical energy. It is typically used after isolating a section of the network, ensuring that no accidental voltage remains. Key components include:

  • Contacts: Heavy-duty contacts for secure grounding.

  • Insulation: Ensures safe operation during switching and in standby position.

  • Operating Mechanism: Manual or motorized actuators for controlled operation.

  • Interlocks: Prevent operation under unsafe conditions.

Degatech grounding switches can be integrated into switchgear panels, ring main units (RMUs), or used as standalone devices in substations.
