What is a diaper cable?

The diaper cable was made to meet the standards of fire safety set by modern building regulations for cables - electric and roads. The building of the building passes, the spaces usually above the ceiling drops where air can circulate. In most places, including the US, safety standards require that the cable be highly resistant to flame and when burning to emit a relatively low level of smoke and vapors. The diaper cable is commonly cloak in Teflon®, while the cable that is operated in vertical risers from the floor to the floor is produced for less strict specifications and is usually shaped in cheaper PVC.

In modern design, diapers are an integral part of the structure of the structure. Most American buildings are built with a standard height from floor to ceiling 8 feet (2.43 meters), but the actual height is usually 10 to 12 feet (3.05-3.66 meters), while the ceiling suspended under the actual ceiling created 8-foot ceiling. The space above the drip ceiling is a diaper. Critical components of the infBuilding rack, such as ventilation offers and return channels, plumbing and electricity and communication cables, are installed in diapers. In some cases, the elevated floor creates a plenum under it through which plum cables are operated; This is commonly found in rooms built primarily for housing computers.

Using a cable with a diaper rating is a problem especially in larger buildings, where thousands of feet (meters) of the cable are held in the diapers. Although there is no significant factor in building small residential structures, it justifies the cost of the cost of buying both types of cables and possibly used in a larger structure, such as the office tower or apartment building. Plenum cable with higher value can be used in risers, but the climbing cable may not be used in diaper. The cost of the cost, Tygh, justifies the Riser cable for vertical cable runs, while the intersections in each patRespects diaper cables for distributing power or signal to different places on each floor. It is necessary to pay attention to the risers' design and where they meet diaper to ensure that they do not accept the attributes of diapers, which requires a plunum cable.

growing concerns between fire safety experts is leaving the old cable inside the riser and diaper of the structure. Upgrading the infrastructure of the structure or IT systems of the tenant often requires new cabling. Replaced by the device is disconnected from the cabling and replaced, but the cable itself remains in Plums and risers. The concern is that an older cable made for outdated standards of fire resistance can be a threat of fire and smoke, even if it is no longer used.
