The water spray systems should have isolation facilities so as to enable periodic testing, maintenance etc. Normally, all cut-off valves should be locked open. The high velocity water spray system for transformer protection operates on the same principle as a deluge system. The detectors mounted on a separate pipeline on detecting the fire releases the compressed air within the pipe, thereby operating the deluge valve. This allows the water to flow out through the projectors in the form of high velocity water spray and extinguishes the fire. Generally, a water motor operated gong (as in the case of sprinkler systems) sounds the fire alarm. Sometimes, additionally an electrical alarm may also be provided.
We offer best Design & Engineering of an integrated HVW spray system as per national/ international standard and guidelines. During designing we consider that adequate coverage of the entire transformer unit including the conservation tanks; the bushings and the bottom area shall cover by HVW spray system. Our designed system in accordance to international standards is an arrangement of Piping, Deluge & Automatic Value, Nozzle, Q.B. Detectors etc. to make an automatic or manually actuated fixed pipe system connected to a water supply to provide a specific water discharge and distribution over the protected surface of area.
