CABLE TRANSIT SYSTEMS MCT Cable Transit Systems A A Transit System is a means to maintain the A integrity of a firewall, bulkhead or deck through which cables, pipes or other services pass through. The Transit System will seal against and exhibit resistance to : Explosion, Gas, Fire & Smoke, Radiation, EMC & UV Light, Water, Chemicals & Vermin. Total System Inspectability B The colour coded block system provides total inspectability of the transit installation even after installation has been completed. On each of the block faces, minimum & maximum diameters are clearly marked indicating specific sealing range of the block. B Tolerant Block Size Range C Tolerant & filler blocks are available in seven sizes from 3mm - 100mm. Special blocks for non-standard penetrations such as busbars, earthstraps etc also available. Tolerant blocks have five sealing faces that are displaced by the sealing process, resulting in a tolerance of up to 4mm for cable diameters. C Compression Systems Unique steel insert pins on both sides of the Transit System ensure the correct level of compression is applied to each installation ensuring max sealing levels are achieved. Transit Frames D Made of primed or painted mild steel, stainless steel or aluminium, frames are carefully welded and finished in the highest quality. Frames D can be cast within a concrete wall, cemented or bolted into a wall or welded or bolted to a metal bulkhead providing for a range of civil and marine applications. Frames available in single and multiple aperture combinations. EMC Transit Systems Electromagnetic compatibility is achieved by reducing the Electromagnetic Interference (EMI) to a level which in most applications will not disrupt the operations of electronics. A full range of EMC blocks are available. Blocks are coated on all surfaces with a highly conductive silver loaded spray providing excellent shielding ability and a layer of adhesive copper strip around the block aids conductivity. Testing has been carried out to measure Shielding effectiveness, Current Leakage and transient pulse conductivity. 22
