Low Smoke Zero Halogen Cross-linked Polyethylene (LSZH XLPE)

LSZH XLPE combines the excellent mechanical properties of cross-linked polyethylene with the environmental friendly properties of low-smoke, zero-halogen materials, offering significant advantages in cable production.

What is Low Smoke Zero Halogen Cross-linked Polyethylene/What is XLPE?

Low Smoke Zero Halogen Crosslinked Polyethylene (LSZH XLPE) is a polyethylene material modified by a crosslinking process and formulated without halogen elements. It combines the excellent electrical properties of polyethylene with the high heat resistance of a crosslinked structure and the environmentally friendly properties of low smoke and zero halogen. Low smoke zero halogen crosslinked polyethylene can not only work stably under high temperature environment, but also release minimal toxic gases in fire, reducing the environmental pollution and danger in case of fire.

1.Low smoke zero halogen

The most important feature of low smoke zero halogen cross-linked polyethylene is its low smoke release and halogen free characteristics. This material releases very little smoke when burning and does not release toxic halogen gases (such as hydrogen chloride). This makes it less vulnerable to people in a fire, providing a better chance of escape and reducing the hazards caused by fire.

2. Cross-linked structure

Cross-linked polyethylene (XLPE) is a polyethylene material formed through a cross-linking process that results in a tighter molecular chain structure, which significantly improves the material's heat resistance, compression resistance and mechanical strength. The cross-linking structure of low smoke zero halogen cross-linked polyethylene enables it to work stably in high temperature, humidity and harsh environments, which prolongs the service life of the cable.

3. Excellent flame retardant properties

Low-smoke zero-halogen cross-linked polyethylene can effectively inhibit the spread of flame and keep the release of smoke and toxic gases relatively low when in contact with fire. Its flame retardant properties comply with various international standards, such as UL94 V-0, etc., which can effectively reduce the risk of fire and ensure the safety of electrical systems under extreme conditions.

4. High Flame Retardancy

The cross-linked structure of cross-linked polyethylene gives it excellent heat resistance and enables it to withstand high-temperature working environments. This makes low smoke zero halogen cross-linked polyethylene cables suitable for power transmission in high temperature environments, and its excellent thermal aging performance ensures long-term use.

Low Smoke Zero Halogen Crosslinked Polyethylene (LSZH XLPE) Application Areas

LSZH XLPE is widely used in many fields, especially in places with high safety and environmental requirements. The following are the main application areas of LSZH XLPE:

1. Construction Cables

In the construction industry, especially in crowded places such as subways, commercial buildings and residential areas, low-smoke zero-halogen cross-linked polyethylene is widely used as insulation and sheath material for cables. Its low smoke, halogen free and flame retardant properties effectively reduce the risk in case of fire and provide a high level of safety. Reducing the release of toxic gases in case of fire is also an important advantage of low smoke zero halogen cross-linked polyethylene in building cables.

2.Railway Transportation System

Low smoke zero halogen cross-linked polyethylene is widely used in rail transportation systems, especially in systems such as subways and high-speed railroads. Railway transportation cables need to meet strict flame retardant and low smoke requirements, and low smoke zero halogen crosslinked polyethylene perfectly meets these requirements, providing reliable cable protection for the electrical equipment of the rail transportation system.

3. Data Centers And Computer Networks

In data centers and computer networks, cables need to have high safety and stability. Low-smoke zero-halogen cross-linked polyethylene cables are ideal for these environments due to their good electrical performance and flame retardant properties. It reduces the release of toxic gases in a fire and provides higher safety for data equipment.

4. Power And Communication Cables

Low smoke zero halogen cross-linked polyethylene is widely used for insulation and sheathing of power and communication cables. Its heat resistance and chemical resistance make it adaptable to various extreme environments, while its low smoke zero halogen and flame retardant properties make it effective in protecting equipment and personnel safety in case of fire.

5. New Energy Field

Low smoke zero halogen crosslinked polyethylene in the new energy industry, especially photovoltaic cables also have important applications. Its UV resistance, high temperature resistance and anti-aging properties enable it to work for a long time in outdoor environments, ensuring the stable operation of photovoltaic power generation systems.

Technical Advantages of Low Smoke Zero Halogen Crosslinked Polyethylene (LSZH XLPE)

LSZH XLPE has many technical advantages, especially in terms of safety, environmental protection and long-term performance. The following are its main technical advantages:

1. Excellent Safety Performance

Low-smoke zero-halogen cross-linked polyethylene cables release very little smoke in a fire and do not release harmful halogen gases, which greatly reduces the environmental pollution caused by fire and the harm to personnel. This makes low-smoke zero-halogen cross-linked polyethylene ideal for environments that require high safety and security.

2. Strong Heat Resistance And Aging Resistance

The cross-linked structure significantly improves the heat resistance of the material, enabling it to work for long periods of time in high-temperature environments. Low smoke zero halogen cross-linked polyethylene cables are also highly resistant to aging, resisting the effects of UV rays, ozone, and other environmental factors for a longer service life.

3. Excellent Electrical Performance

Low smoke zero halogen cross-linked polyethylene particles have excellent electrical insulation properties, which can effectively prevent current leakage and ensure the normal operation of the electrical system. This enables it to maintain stable performance in high frequency and complex electrical environments.

4. Strong Flame Retardant Properties

Low-smoke zero-halogen cross-linked polyethylene compounds can effectively prevent the spread of flames and low smoke concentration, in line with a number of international cable safety standards. Its excellent flame retardant properties make it effective in reducing the speed of fire spread in case of fire, providing a guarantee for safety.

5. Good Mechanical Properties

Low-smoke zero-halogen cross-linked polyethylene cable material not only has strong pressure and abrasion resistance, but also can effectively resist chemical corrosion and other mechanical damage. This makes it still able to maintain long-term stable performance in complex industrial environments.
