What are the advantages of Lzsh cable?

In case of fire,The advantage of LZSH cable comes into play.LSZH cables do not produce large amounts of smoke and other toxic gases. They are called “environmentally friendly cables”. LSZH cables are typically used in applications where cable fire resistance requirements are high, such as the petrochemical industry, closed sites or dense populations. It is closely related to the cable in working life. Cable quality needs to be improved. There are strict requirements for the fire resistance and low smoke of the cable.

Presentation of the LSZH Cable

LSZH means low smoke, zero-halogen, is a non-halogen and flame-retardant material. Non-halogen means the cable material does not contain fluorine elements, chlorine, bromine and iodine, which can produce toxic substances during combustion. Compliance with ecological environmental protection requirements during production, use and disposal.

PVC cable has flame resistance, but the material contains halogen. When burning, it will produce a lot of soot and toxic gases, which will cause damage to the human respiratory system and the environment. Generally, XLPE material is chosen for the insulation layer, the sheath and outer sheath of the câble LSZH. It has stronger flame resistance. At the same time, it will produce very little soot and gas during the combustion process.

Advantages of Câble LSZH

LSZH cables have many advantages over traditional cables.

  1. High flame resistance, not easy to burn in case of fire. And after burning, you can control the fire within the local range to stop the spread of fire and avoid secondary injuries.
  2. Does not contain halogen, producing a small amount of toxic gas and acid gas when burning, avoiding damage to personnel and equipment during combustion.
  3. The light transmission is greater than 60%, the smoke is thin when burning, which is good for people evacuation and fire fighting work.
  4. The tension resistance is greater than the wire of PVC general: the tension resistance of general PVC wire is greater than 1,05 Kgf/mm2, and the tensile strength of the low-smoke halogen-free wire is greater than 1,2 Kgf/mm2.
  5. It has good thermal resistance (-30℃-105℃) and good sweetness (hardness is 80-90).
  6. The light transmission is greater than 40%, the smoke is thin when burning, which is good for personnel evacuation and fire extinguishing work.
  7. Green environmental protection equipment, has good waterproof and anti-uv ability, extend the lifespan.

Application

LSZH cables are generally used in schools, shopping centers, Hospitals, residential buildings, the underground, tunnels and other fire-prone and densely populated locations, with high demands for safety.

In the event of a fire in a tunnel or dense cable metro line, there is a significant risk. We all know that a fire produces flames and smoke, but it’s the smoke that’s the most dangerous part. In the tunnels, where ventilation is limited, smoke can quickly cover the entire tunnel, reducing visibility or obscuring escape routes, creating a significant risk. Using LSZH cables can avoid this problem, reduce smoke buildup and fire expansion, help protect staff from smoke, toxic gases.

LSZH cable is also widely used in the military. There are a variety of precision instruments and electronic equipment in aircraft, the tanks. And the space is more confined, it can effectively improve safety and protect personnel equipment.

  1. The sheath or protective layer material of ordinary cable contains halogen, which releases toxic gases and corrosive gases during combustion, what harms the physical health of people. Rescuers must wear gas masks for rescue. LSZH cables do not contain halogen and do not produce toxic gases during combustion, which guarantees the safety of personnel.
  2. LSZH cable has very good flame resistance, and can effectively organize the spread of fire in the event of combustion, which makes it easier to control the fire. Ordinary cables do not have flame retardant material. When burning, the flame diverges along the cable line, which expands the range of combustion.
  3. The common cable burning process will produce a large amount of soot, environmental pollution along with continuously collected soot will block the road to prevent rescuers from launching operations. However, combustion of LSZH cable produces only a small amount of soot and can reach low smoke levels.
  4. LSZH cable is suitable for places that require high environmental protection, narrow space and dense staff. Ordinary cables are more used in emptier areas.

Conclusions

LSZH cable has the advantage of being flame retardant and producing little smoke., which enables safe power transmission while meeting environmental requirements. And with the upgrade of technology, previous deficiencies in electrical properties and physical characteristics have been strengthened, compared to other flame retardant cables have better flexibility and bend radius. The price is more expensive compared to ordinary cable, but with increasing market demand for environmental cable, the tracking price will gradually decrease.
