12kV environmental protection inflatable ring network cabinet

Back to superior

Product name: 12kV environmental protection inflatable ring network cabinet

product description

Environment-friendly inflatable ring network cabinet is based on the advanced production, manufacturing and inspection of the original SF6 gas insulated ring network cabinet. It is a new generation of high-tech, energy-saving, clean and environmentally friendly switch equipment developed by low-pressure N2 to completely replace SF6 gas. Changing the user's operation and maintenance habits can provide users with a new, intelligent, efficient and green experience.

Performance characteristics

The box adopts laser welding sealing technology and vacuum helium leak detection, which has strong environmental adaptability

Gas tank is filled with slightly positive pressure N2 to prevent moisture intrusion from affecting the gas tank insulation

Under the condition of zero gauge pressure, it can ensure the product's safe and reliable operation and high power supply quality.

No toxic and harmful substances to the human and environment are generated during the operation of the equipment

No need to recycle gas after product reaches its life cycle

The equipment adopts environmentally friendly insulation materials, and the recycling rate of materials reaches 90% -95%
