Firestop Speed Sleeve: Many times, it is noted that to reduce the number of penetrations in a building for low voltage, medium voltage cables, designers tend to design circular cores in the building. These circular cores later are used for electrical cables to pass from one compartment to the other. This is why the industry has introduced multiple kinds of sleeve devices which can be simply installed with minimal training. These devices also come of greater advantage to a building owner because it can be repenetratable by simply opening it and passing the new cables. And the same way cables can be removed too. Please find below the picture of one of such devices. Innovation in Firestop Cable Transit Systems for Industries: It has been seen that industries often desire a Firestop system with much more capability than only providing Fire Resistance Rating. Some of the common demand from industries is that such Firestop systems shall protect the high voltage cables of larger diameter by protecting it individually. This is where architects and designers can refer to cable transit systems that can withstand up to certain blast pressure and protect the cables individually. Please find below the picture of one of such devices. 181
