What is Lszh conduit?
Its proprietary formulation of thermoplastic polyurethane combines low smoke, flame retardation, and toxicity generation characteristics, virtually eliminating hydrogen chloride, hydrogen fluoride, and hydrogen bromide gases during a fire. …
Is LSZH flame retardant?
Low Smoke Zero Halogen (LSZH) cable has a flame-resistant jacket that doesn’t emit toxic fumes even if it burns. LSZH cables usually cost more than the equivalent PVC cable, and certain types are less flexible.
What does low halogen mean?
Within Intel, the term “low-halogen” is defined in Clause 4 of JEDEC JEP 709 and is used to identify solid state devices that contain low concentrations of bromine and chlorine from brominated and chlorinated flame retardants (BFRs, CFRs).
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.
Is LSHF the same as Lszh?
LSHF Cable – Low Smoke Halogen Free. LS0H Cable – Low Smoke 0 (zero) Halogen. LSZH – Low Smoke Zero Halogen.
What is low smoke wire?
Low smoke cable/wire, also called limited smoke cable, refers to cables where the cable jacketing and insulation is made with materials that produce no or only small amounts of smoke when exposed to fire or high temperatures. These low smoke cables are used when halogen considerations are minimal.
Why is halogen free important?
When a plastic containing halogens burns, these halogens are released from the jacket and get into the breathing air. The combination with water produces an acid that is toxic to humans. Halogen-free is therefore particularly important if the user has to pay particular attention to the danger posed by a potential fire.
What is low smoke and fume cable?
LSHF cables are made up of halogen free compounds that are good fire retardants but emit less than 0.5% hydrogen chloride gas and smoke when burnt. In case of fire these cables produce small amounts of light grey smoke and HCL gas which greatly increases the chances of escape from populated areas.
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.
