Product Overview丨
V-12 Environmentally Friendly Gas-Insulated Metal-Enclosed Switchgear
Overview:
Sulfur hexafluoride (SF₆) circuit breakers, due to their use of high global warming potential (GWP) greenhouse gases, are being progressively replaced by eco-friendly alternatives, such as switchgear utilizing dry air or low-GWP gases like C4F7N. The design and functionality of the V-12 switchgear focus on environmental protection, safety, and efficiency, making it ideal for scenarios with strict environmental requirements.
Application Scenarios:
The V-12 eco-friendly gas-insulated switchgear is used as an incoming, outgoing, or tie-line unit in 12kV systems, typically installed in urban substations and switching stations to enable power distribution and control. Its fully sealed structure provides excellent protection against external corrosion, especially in coastal high-salinity or humid environments.
Advantages:
Replaces traditional SF₆-based equipment
Complies with the EU F-gas regulations and China’s Measures for the Environmental Management Registration of New Chemical Substances, both of which limit high-GWP gases
Reduces carbon emissions, supporting carbon neutrality goals
Safety Features:
The switchgear is equipped with five-interlock protections, preventing dangerous operations such as:
Incorrect breaker operation
Load operation of disconnectors
Grounding switch errors
Mechanical or electrical interlocks prevent unsafe actions, such as opening the cabinet door when the grounding switch is not engaged.
Operator-Friendly Design:
The cabinet features a visualized front door design, including a transparent window and built-in lighting. These allow operators to clearly view the breaker position and cable connection status, assisting in safe and accurate operation.
