Low Smoke Zero Halogen Flame Retardant and Fire Resistant Power Cable

Low smoke halogen-free flame retardant cross-linked polyethylene insulation power cable is a new type of power cable with high safety, environmental protection and mechanical protection. Compared with ordinary cables, this cable has stronger resistance to compression, tension and mechanical damage, and is suitable for use in environments requiring high safety and high damage resistance.

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

High-rise buildings:In high-rise buildings, the use of low-smoke halogen-free flame-retardant cables can effectively reduce the generation of smoke and avoid the release of harmful gases, thus winning precious time for the evacuation of personnel.

Subways and transportation hubs:Transportation hubs such as subways, railway stations, and airports are crowded places. Low-smoke halogen-free flame-retardant cables can effectively curb the spread of flames in fires, reduce the release of toxic gases, and ensure the normal operation of the power system.

Hospitals and medical facilities:Low-smoke halogen-free flame-retardant cables can avoid secondary damage to patients and medical staff caused by toxic gases generated by cable combustion, and ensure the normal operation of medical equipment.

Large commercial buildings and shopping malls:The flame retardant and low-smoke properties of low-smoke halogen-free flame-retardant cables can not only effectively prevent the spread of fires, but also reduce the release of harmful smoke, providing sufficient evacuation time for people in shopping malls.

Industry and mining areas:Low-smoke halogen-free flame-retardant cables can effectively prevent fires caused by power equipment failures, especially in closed environments such as underground mining areas, effectively protecting the lives of miners.

Communications and data centers:Using low-smoke halogen-free flame-retardant cables can avoid fires or downtime problems caused by power cable failures and maintain long-term stable operation of equipment.

 

 

Construction

 Solid, Stranded Copper or Aluminum

Insulation

 XLPE

Amouring

1)Non-armoued
2)Steel tape armoured (STA)
3)Steel wire armoured(SWA)
Aluminum wire armoured(AWA)

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.
