tailieunhanh - The Effect of Moisture

This white paper will focus on issues related to moisture and its effects on UTP Plenum cabling solutions. For the purpose of argument we will be looking beyond standards and testing for issues that, quite frankly, should never happen under normal circumstances. However, as many of us who have been in the industry for a number of years realize, sometimes the unlikely becomes reality! | TrueNet AirES Technology The Effect of Moisture Ingress on AirES Cable This white paper will focus on issues related to moisture and its effects on UTP Plenum cabling solutions. For the purpose of argument we will be looking beyond standards and testing for issues that quite frankly should never happen under normal circumstances. However as many of us who have been in the industry for a number of years realize sometimes the unlikely becomes reality TrueNet AirES Technology The Effect of Moisture Ingress on AirES Cable The industry bodies have this to say about wet and dry locations BICSI TDM manual 9th edition Chapter 4 - Horizontal Distribution Systems Section 1 - Horizontal Pathway Systems final paragraph of page 4-5 which states Wet Locations Intrabuilding horizontal pathways shall be installed in dry locations that protect cables from moisture levels that are beyond the intended operating range of inside premises cables. For example slab-on-grade construction where pathways are installed underground or in concrete slabs that are in direct contact with soil . sand gravel etc. are considered to be wet locations. In the United States see the NEC Article 100 for definitions of damp dry and wet locations. NEC Article 100 - Definitions Locations Damp locations Partially protected locations under canopies marquees roofed open porches and like locations and interior locations subject to moderate degrees of moisture such as some basements some barns and some cold-storage warehouses. Dry Locations A location not normally subject to dampness or wetness. A location classified as dry may be temporarily subject to dampness or wetness as in the case of a building under construction. Wet Locations Installations underground or in concrete slabs or masonry in direct contact with the earth or other liquids such as vehicle washing areas and locations exposed to weather and unprotected. The above being said let s have some fun. The AirES cabling innovation incorporates air .
