Components of a SIC Multi-Cable Transit System
The cables pass through a frame which has been properly welded on a bulkhead or embedded on a wall or ceiling. Frames are supplied in standard sizes according to a modular system.
The empty spaces in between the inside of the frame and the cables are filled with insert blocks made from elastic material resistant to fire. Cables and insert blocks are placed in rows inside the frame according to their diameter. On this way, using spare blocks if necessary, the whole set is sealed.
In between each row of blocks it is advisable to insert an anchoring plate. This will keep the blocks in position and help the distribution of the pressure through the frame. Insert blocks are compressed by a press plate which assures the necessary tightness. The resulting empty space is filled with an end closure, also made of elastic material, which will complete the system.
