“The Last Cable Standing”

Fire: a serious problem Fires have a high cost in terms of loss of human life and of damages to plants and

structures.

About a third of fires originate inside buildings.Research studies in this field state that the

most commonly identified cause of death from a fire accident is being overcome by gas or

smoke (Department for Communities and Local Government - formerly ODPM - Fire Statistics,

United Kingdom, 2005).

Other influential sources have demonstrated that for the last 50 years, the average time

from ignition of a fire to flashover has gone from 15 minutes to 3 minutes, thus seriously complicating the escape from fire. And this is

due only to the increase of plastics in home and buildings.

It has to be kept into consideration, then, that even the most sophisticated alarm systems or emergency systems can be useless if

their performances are compromised by the destruction of the cables because of the fire. This

is the reason why, over the last few years, the companies have strongly invested in design and

development of insulation material and of cables granting the best performances in case of fire, while reducing fumes and acid gases emission

and granting the circuit integrity even in case of fire.

Cavicel has been present for years onto the market with its own products and its own experience.

Bare copper braid forelectromagneticinterferenceorwhenthecableissubjecttomovements

Aluminium/polyester or copper/polyester tapes normally have a total thickness from 25 to 100 µm, according to standards and are wrapped with an overlap >125% to assure a full coverage even in case of bending.In continuous contact with metallic side there could be an earth tinned conductor, same cross section of the other cores, or a drain wire, normally tinned copper, 0.5 sqmm, stranded or solid, according to cable specifications.Copper braid normally has a coverage from 80% to 95%. This type of screen presents a lower electrical resistance, a very good protection also to electromagnetic noises and a higher mechanical resistance compared to aluminium/polyester tape. It is suitable for mobile applications.
