Low smoke zero Halogen cable used in public and government buildings and where there is sensitive electronic equipment (i.e. Hospitals, Supermarkets, Airports, Control Rooms & Computer Suites) these cables are designed for increased safety in the case of a fire:Reduction in hazardous fumes which can cause injury when inhaled; Reduction in corrosive chemicals which can cause damage to electronics; Most cables used in installations have been insulated with PVC or similar materials.XLPE Insulated halogen-free low smoke cable may prevent human from being suffocated by toxic gas generated from accidental burning of wire and cable.Such asfire-resistant flame-retardant cable, do not catch fire easily and do not spread the fire or give off toxic gas when on fire.They are suitable for using in the circumstance with fairly strict flame retardant and environmental protection requirement,such as high-rise buildings,hospitals,subways and shopping malls.
Property: 1) The temperature of laying cable is not lower than 0oC. 2) Max. continuous normal operating Temperature: 90oC 3) Max. permissible temperature at short circuit (5s. at longest): 250oC. 4) Permissible bending radius: Single core: ≥20(d+D)±5%. Three-core:≥15(d+D)±5% (D is the actual overall diameter of cable, and d is the actual overall diameter of conductor).
LSZH Cables intended to fulfil this type of function are often labelled as one of the following: LSZH - Low Smoke Zero Halogen LSOH - Low Smoke Zero Halogen LSF - Low Smoke and Fume OHLS - Zero Halogen Low Smoke Both LSZH and LSF are used to limit smoke, fumes and halogen given off in fire conditions.
