Thanks to the use of water mist and its remote control, the firefighting robot is a safe extinguishing variant for transformer fires
When transformers or substations catch fire, extinguishing is always a very delicate and challenging task. Since water conducts electricity, water is not a suitable extinguishing agent and sometimes even prohibited. The device, for example, if exposed to a full water jet on live parts, could overturn the voltage and thus injure or even kill a firefighter.
The use of other extinguishing options such as carbon dioxide or metal fire powder is not without risk. Therefore, people have begun to look for further alternatives and recognize that water mist is very well suited.
Water mist consists of many small individual droplets that are not connected, which means they do not conduct electricity. The use of water mist in burning transformers or substations is therefore mostly harmless.
At EmiControls, we specialize in firefighting using water mist, better known as the development of highly effective and innovative firefighting turbines. The turbine is equipped with a nozzle ring, which atomizes water into fine aerosols. This water aerosol is distributed using propellers and reaches over 50 meters in the aerosolized state and 75 meters in the full jet.
