Cable tunnels are narrow tunnels for electric facilities of medium or high tension that supply infrastructures and critical facilities like electric plants, substations, central electrical grids, telecommunications, etc. 

Any alteration to these elements can result in cuts in the electrical service, security incidences, damage to other equipment, production stoppages and interruptions of all types in the economic and productive activities that depend on them.


It functions automatically, thus preventing damages or even the collapse of the installation in case of a fire.


Thanks to its performance mechanism, it blocks the liberation of heat that could affect materials, or could extend the fire to the tunnels, namely those alleys that are frequently used without the presence of security personnel or are difficult to access or register.
