What is LSOH low smoke zero halogen tray cable?
LSOH or LHZH is used to name the cable that hardly emits smoke and no halogen in case of a fire. Previously it used to be flame retardant cables that had halogens and it was only the cables that were not flame retardant that had no halogens. So this product has brought about a lot of raised eyebrows because of its unique specifications.
What is the difference between PVC and LSOH cables?
PVC is more flexible and comes with a softer outer sheath. In case of a fire, PVC cable will burn and give off a heavy black smoke while LSIH cables will give out very little smoke. PVC cables can give out hydrochloric acid and other toxic gases too when it is exposed to fire.
Why are flame retardant cables dangerous if they have halogens?
Normally a cable that is resistant to fire will have halogens in the compound that will reduce the flammability of the cable. This will cause the cable to release toxic gases such as hydrogen chloride that will become hydrochloric acid when it comes in contact with water. So, that is where LSOH cables are preferred as they do not have any halogens in the compound that makes the cable flame retardant and therefore, no halogens released when exposed to fire.
Can I use LSOH cables in my house?
Yes, you can although most LSOH cables have been specially developed for use in industries working under hazardous conditions. Nevertheless, today you see just about anyone looking out for LSOH cables as they are considered safe for use especially in places where there is no proper ventilation. However, you might have problems with its flexibility as PVC cables can bend more than LSOH ones, but people prefer LSOH cables because they look better than PVC ones.
Are LSOH cables very expensive?
Well, they were expensive a few years ago, but not anymore as its demand in the market has increased. Many prefer to use LSOH these days and that has made cable industries and engineers interested in producing such cables at a lower cost. However, when you compare it to the cost of an equivalent PVC cable, then it will be more.
Can I expect any problems when using a LSOH tray cable?
When the cables are installed at high temperatures such as 500C or when exposed to high energy UV rays, you can expect to see a few cracks in the outer sheath. To combat the problem, the extruder can have a higher setting for temperature. Cracking can also occur when the installer uses excessive lubricant. The excess lubricant must be removed and not allowed to settle especially around joints.
