Abstract

PURPOSE:To prevent spread of fire of group cable, by ejecting water and carbon dioxide radially from the central portion of cable. CONSTITUTION:Holes 3 are made with predetermined interval through a pipe 2 burried in radially central portion of a group cable 1 comprising various types of cables C1-Cn. One end of the pipe 2 is coupled with a water storage tank 7 for supplying water to the pipe 2 and a carbon dioxide gas tank 8, while the other end thereof is sealed. A plurality of fire detectors 5 arranged with predetermined interval along the pipe 2 are connected with a controller. A signal detected through the fire detector 5 is transmitted to the controller 6 which outputs a control signal for operating the water storage tank 7 and the carbon dioxide gas tank 8. Fire of the group cable 1 can be prevented from spreading by ejecting water and carbon dioxide gas simultaneously through the holes 3 of the pipe 2.
