The product uses sulfur hexafluoride gas with good insulation performance as the insulating extinguishing medium, which greatly reduces the volume of the substation. The charged part is closed with a metal shell, which is not affected by the external environment, and is shielded from electromagnetic and static electricity, with low noise, strong anti-radio interference ability and excellent anti-seismic performance. Suitable for areas with harsh environmental conditions.
