Cable for the fire alarm system fire-resistant Hastel Kablo J-Y(St)Y Lg 2х2х0,8 to buy in Kiev, reasonable price
Devices which log in the fire and security alarm system require professional installation in which high-quality expendables as J-Y(St)Y Lg will be applied. Otherwise degree of protection of the object, and also reliability the general of all equipment and its functioning will decrease.
For today's time the alarm system which can be fire or security can be even an obligatory component practically of each office, the room of a warehouse, the hall for trade, and also many houses and apartments.
And so, the most important element in such systems is the cable for the alarm system. Thus, it is possible to select some characteristics by which the cable for the alarm system is determined.
1. The cable for the alarm system has to be reliable. If the cable is interrupted, then it will not be rescued even by the most perfect system of the alarm system and the most thinly adjusted sensors and sensors. And characteristics of a cable will depend on where the cable is located. And if the cable is indoors, then the PVC cover as PVC a cable is necessary here. And if the cable is located on open space, then in this case it is necessary to use svetostabilizirovanny polyethylene and special, a cable which is strengthened. It is natural that isolation should not extend burning.
2. As a wire the multicore copper wire or couple twisted has to act.
3. In such cables there has to be a good capacity. For system of the alarm system security and fire or video surveillances, such cable which is capable to transfer data of wasps by speed not less, than 2 MB in a second is necessary.
