12kV Metal Solid Insulated Switchgear

The 12kV metal solid insulated switchgear combines the advantages of indoor and solid insulation:

1. Fully insulated and sealed: All high-voltage live parts are covered by a solid insulation layer, which is not affected by dust, moisture, condensation, small animals, etc. It has high reliability.

2. Miniaturization and compactness: The dielectric constant of solid insulation materials is much higher than that of air, so the insulation distance between live parts can be significantly shortened under the same voltage level. Therefore, the equipment is very small in size, saving floor space, which is crucial for indoor distribution rooms with limited space.

3. Environmentally friendly: It completely eliminates SF₆ gas, eliminating the risk of greenhouse effect, and is the preferred equipment for green power grids.

4. High safety: Since the high-voltage components are fully insulated, even if the cabinet door is open, the operator will not directly touch the live parts, ensuring great personal safety.

5. Maintenance-free: The internal switches and other components are solidified in epoxy resin, without any need for lubricated moving parts, achieving lifelong maintenance-free, reducing operation and maintenance costs and workload.

6. Flexible installation: Small in size and light in weight, it is convenient for transportation, installation and arrangement indoors. The modular design also facilitates future expansion.

Where can this switchgear be used?

12kV metal solid insulated switchgears are widely used in power distribution areas that require safety, reliability and space-saving:

· Commercial buildings: Underground power distribution rooms of office buildings, shopping centers, and hotels.

·Residential areas: Central power distribution centers within the residential communities.

· Industrial enterprises: Workshop substations within factories.

· Public facilities: Power distribution systems of subway stations, airport terminals, hospitals, schools, etc.

· Data centers: In situations where high reliability of power supply and high space utilization rate are required.

· New energy field: Indoor step-up stations for photovoltaic/wind power projects.
