Low Smoke Zero Halogen Flame retardant Power Cable

Product Description
LSZH cable known as Low Smoke Zero Halogen cable / LFH (Limited Fire Hazard) cables are made of insulation materials that emit limited or low smoke and non toxic halogens when exposed to high temperature or fire. Low smoke cable and halogen free cables often used in hazardous environments and poorly ventilated areas.
Application
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 as fire-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.
Construction
Conductor | Solid, Stranded Copper or Aluminum |
Insulation | XLPE |
Amouring | 1)Non-armoued |
Sheath | LSOH material |
Characteristics
1)Rated voltage: 0.6/1kV
1)The temperature of laying cable is not lower than 0°C.
3) Max. continuous normal operating Temperature: 90°C
4) Max. permissible temperature at short circuit (5s. at longest): 250°C.
5) 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.
Safety features
Flame retardancy:The cable complies with the IEC 60332 standard. When a fire occurs, it can effectively prevent the spread of flames, avoid the expansion of fire, and ensure the safety of the power system.
Low smoke and halogen-free:The cable adopts low smoke and halogen-free materials, which complies with the IEC 60754 standard. It can reduce the release of toxic smoke in fires and greatly reduce the harm to personnel and equipment. It is especially suitable for crowded places.
Electrical safety:The cross-linked polyethylene (XLPE) insulation layer has excellent voltage breakdown resistance, which can effectively prevent electrical failures and ensure the safe operation of the power system.
Mechanical protection:The cable adopts steel belt armor, which provides it with excellent mechanical protection. Even in the case of external impact or extrusion, the cable can maintain a high stability to avoid power outages due to external damage.
Advantage:
LSZH cables, low smoke low halogen characteristics, when a fire occurs, slow the spread, low smoke density, high visibility, harmful gas emissions small, easy evacuation. Combustion gas is less corrosive, but also to avoid damage to equipment, low-halogen, halogen-free, which makes the cable materials greatly enhance the anti-aging and resistance to ultraviolet radiation and other properties, thus extending the life.
