LSZH Cables: Preventing Fires Before They Start

In contemporary society, with the acceleration of urbanization and the enhancement of people's awareness of safety and environmental protection, LSZH cables, as a new type of cable material, are gradually becoming the new favorite in the market. LSZH cables play an important role in fire prevention, truly achieving "preventing problems before they happen".

Definition of LSZH Cables

LSZH cables are composed of thermoplastic or thermosetting materials that emit low smoke when heated and do not contain halogens themselves. Most network cable jackets are made of polyethylene, polyvinyl chloride, or thermoplastic polyurethane. If ignited, chlorine-containing plastics will release toxic hydrogen chloride, which can produce hydrochloric acid when it meets water.

The Role of LSZH Cables

LSZH cables do not release hydrogen halides or other acids when ignited. These cables are often used in poorly ventilated environments such as airplanes, train compartments, or ships. They are also widely used in the railway industry because there are high voltage lines or signal lines for train location beneath railways. Using LSZH cables reduces the accumulation of toxic gases when lines are damaged due to fire or short circuit. In industries like railways or shipbuilding, a significant demand is to protect personnel and equipment from toxic, corrosive gases. In these scenarios, it is required to use LSZH materials on the outer layers of wires and cables.

Performance of LSZH Cables

LSZH cables also have high fire resistance, anti-aging properties, long lifespan, and good safety performance. Their insulation layer is made of special materials that not only have good flame retardant properties but also maintain integrity in a fire, effectively preventing the spread of fire. Additionally, LSZH cables have good corrosion resistance and stability, enabling them to maintain stable performance under various environmental conditions, thereby improving the safety and lifespan of the cables.

In the power, construction, transportation, and many other industries, LSZH cables have been widely applied. Especially in densely populated places with extremely high safety requirements such as subways, tunnels, and high-rise buildings, LSZH cables have become an indispensable part. As a LSZH cable manufacturer, JENUIN cable provides various types of LSZH cables with over 20 years of experience in designing, manufacturing, and selling environmental-friendly LSZH cables.
