Abstract

PURPOSE: To make the promotion of saving a labor required for the work, with a requirement eliminated for installation of the fire-extinguishing water tubing, by means of combining the pole, hollowly constructed, of a noise-proof tank with the fire-extinguishing water tubing, to which a fire-extinguishing nozzle is installed.
CONSTITUTION: A pole 5, likely as circular tube or angular duct, is formed into a hollow pattern, further installed to be used also for the fire-exringuishing water tubing, and to the pole 5 are installed many fire-extinguishing nozzles 6 facing an oil-filled transformer tank 2. And said pole 5, linked to each other, is connected to a water pump. The constitution, in which the pole of the noise-proof tank is constructed by a material of hollow pattern and utilized for the fire-extinguishing water tubing in such manner as said, completely eliminates a requirement of the fire-extinguishing water tubing, capable of remarkably saving a labor required for the work of fire-exringuishing device, as well as capable of simplifying the construction within the noise-proof tank.
