Why is smoke cable low?
When burned, a low-smoke zero halogen cable emits a less optically dense smoke that releases at a lower rate. During a fire, a low-smoke cable is desirable because it reduces the amount and density of the smoke, which makes exiting a space easier for occupants as well as increases the safety of firefighting operations.
What is low smoke Cat 6 cable?
Cat6 Low Smoke patch cables, or LSZH or LS0H, are manufactured using Low Smoke Zero Halogen UTP stranded cable. Each cat6 low smoke cable is fully moulded and fitted with high quality RJ45 connectors.
Should I use low smoke cable?
The use of LSOH cables is not a requirement of BS 7671 in domestic or Non-domestic buildings at present. The use of these cables is often subject to specification requirements rather than regulation. Regulations, however, may soon require such cables when installed in escape routes in certain buildings.
What is the difference between LSZH and LSF?
LSF cable will emit toxic gases while LSZH will limit the emission of these (typically under 0.5% hydrogen chloride emission). The use of LSZH cables protects both people and limits the amount of equipment damage during a fire situation.
Is XLPE low smoke?
Low Smoke XLPE Armoured Cable SWA 3 Core 2.5mm 6943XLSZH In the event of a fire, this type of sheath will emit very low levels of smoke, and non-toxic levels of poisonous halogen gases (typically under 0.5% HCl emission). This type of sheathing is mainly recommended for use in highly populated enclosed public areas.
Where Should low smoke cable be used?
Because the purpose of LSZH cables is generally to minimise risk from the after-effects of an electrical fire like gas and smoke inhalation, they are generally used in large public spaces where there is a risk of fire.
Is NYMJ cable low smoke?
This range of cables have an oversheath made from a Low Smoke Zero Halogen (LSZH) materials, making them suitable for installation in buildings with a high concentration of people or valuable property, where improved fire characteristics are needed.
What is LSF material?
LSF (Low Smoke & Fume) Cables LSF cables are usually made up of a modified PVC compound which produces somewhat less HCL gas and smoke on burning than PVC. These cables are not recommended for public, large commercial buildings, near sensitive electronic equipment and where escape is limited in case of fire.
Is XLPE cable low smoke?
Low smoke zero halogen (hereafter referred to as LSZH but also called LSOH, LS0H, LSFH or OHLS) is a material classification that is common to cable and wire casings. There are several similar classifications such as low smoke and fume (LSF) and low smoke varieties of PVC and cross-linked polyethylene (XLPE).
What does NYM-J mean?
The NYM Cable is for fixed wiring, available as NYM-J (with green/yellow core) and NYM-O (without green/yellow – part numbers with an -O as a suffix). As with many fixed wiring cables, it has a Class 1 solid or Class 2 stranded copper conductor.
What is NYM-J cable?
NYM-J Cable is PVC insulated, PVC sheathed Grey 300/500 volt rated to BS EN 50265-2-1. NYM-J. NYMJ cable is commonly installed in industrial and home application. The cable is designed for dry, moist, or wet open areas i.e under plaster and in concrete.
What does LSF cable stand for?
Low Smoke & Fume
LSF (Low Smoke & Fume) Cables.
