Summary Can The Water Mist Of Rescue Equipment Extinguish Electrical Fires?

Can the water mist of rescue equipment extinguish electrical fires?
Water mist is a fixed fire extinguishing system that uses a special nozzle to decompose the water flow into small water droplets under the working pressure (usually the pressure of the nozzle is 10MPa). The droplet diameter sprayed by the nozzle is the water droplet with Dv0.50 less than 200μm or Dv0.99 less than 400μm, that is to say, 99% of the droplet diameter is less than 400μm, Rescue Equipment and 50% of the droplet diameter is less than 200μm.
Many friends are asking whether water mist can extinguish electrical fires? The editor here clearly tells you that the water mist fire extinguishing system can put out electrical fires, and there is no electrical conduction. Why is this?Rescue Equipment
Rescue Equipment.The diameter of the fine water mist sprayed under the special nozzle is very small and discontinuous. It can be suspended in the air for a long time. It takes a long time and a large number of droplets to complete the condensation of the water mist. After encountering fire, it will quickly vaporize, and it is difficult to form a conductive continuous water flow or surface water on the surface of the electrode. Therefore, the water mist fire extinguishing system has good electrical insulation performance and can effectively extinguish electrical fires.
