In-Depth Guide: Low Smoke Halogen-Free Copper Core Cross-Linked Polyethylene Power Cables (LSZH Cable)

In-Depth Guide: Low Smoke Halogen-Free Copper Core Cross-Linked Polyethylene Power Cables (LSZH Cable)

The Low Smoke Halogen-Free (LSZH) Copper Core Cross-Linked Polyethylene (XLPE) Cable is a high-performance power cable designed for environments that demand both safety and reliability. This cable type offers flame retardancy, low smoke emission, and halogen-free materials, making it ideal for installation in high-risk areas such as subways, hospitals, high-rise buildings, and data centers. In this article, we’ll explore the key features, specifications, and applications of LSZH Power Cables, helping you understand why they are a top choice for critical infrastructure.

1. Key Features of Low Smoke Halogen-Free Copper Core Cross-Linked Polyethylene (XLPE) Cable

1.1 Low Smoke and Halogen-Free Design

The LSZH cable is specifically engineered to emit minimal smoke and no halogen gases during fire incidents. This is a crucial safety feature in enclosed spaces like underground railways, airports, hospitals, and other high-density buildings. The low smoke halogen-free material reduces the release of toxic gases, thus protecting both people and equipment in case of a fire.

1.2 Flame Retardant Properties

LSZH cables meet the flame retardant standards, ensuring that the cable itself does not contribute to the spread of fire. Even in the case of fire, the flame retardant power cable will limit fire propagation, enhancing the safety of buildings and infrastructure where fire risk is a concern.

1.3 Copper Core with Cross-Linked Polyethylene Insulation

The copper core ensures excellent electrical conductivity and reliable power transmission. The cross-linked polyethylene (XLPE) insulation provides high thermal stability and resistance to aging, ensuring that the cable can operate in environments with high temperatures (up to 90°C in normal conditions and up to 250°C in short-circuit scenarios).

1.4 Environmentally Friendly

As a halogen-free cable, the LSZH cable has minimal environmental impact during both manufacturing and use. It does not release harmful substances into the atmosphere, making it an eco-friendly choice for modern, sustainable buildings.

2. Technical Specifications of LSZH Copper Core XLPE Power Cables

The Low Smoke Halogen-Free Power Cable comes with a range of technical parameters designed to ensure its effectiveness and safety in various applications. Below are the key specifications:

· Rated Voltage: Available in multiple voltage ratings such as 750V, 0.6/1kV, 1.8/3kV, 6/10kV, 8.7/15kV, 12/20kV, and 26/35kV.

· Operating Temperature: The cable can operate at temperatures up to 90°C in normal conditions and up to 250°C during short circuit situations (for a maximum duration of 5 seconds).

· Fire Resistance: The cable complies with flame retardant and fire-resistant standards, ensuring it doesn’t contribute to fire escalation.

· Mechanical Strength: The cable is highly resistant to mechanical damage and is designed to endure harsh physical environments.

3. Applications of Low Smoke Halogen-Free Copper Core XLPE Cables

Due to its safety, reliability, and environmental benefits, the LSZH power cable is highly suitable for use in various high-risk environments. The cable’s features make it the perfect choice for:

3.1 Subways and Railways

In underground transportation systems like subways and railway stations, safety is paramount. LSZH power cables provide reliable electrical power while significantly reducing the risk of fire hazards. These cables are designed to keep the electrical system running even in emergency situations, ensuring both people’s safety and the continued operation of the transport network.

3.2 Airports

Airports are complex environments with high foot traffic and critical infrastructure. The low smoke halogen-free properties of LSZH cables make them ideal for use in terminals, hangars, control towers, and other facilities, ensuring electrical systems remain safe and operational under extreme conditions.

3.3 Hospitals

Hospitals require flame retardant power cables that can function under critical conditions. The LSZH copper core cables provide superior fire protection and reliable power supply to life-supporting systems, operating theaters, and intensive care units, ensuring the safety of both patients and staff.

3.4 High-Rise Buildings and Commercial Complexes

In modern, high-rise buildings, especially those with large numbers of occupants and sensitive equipment, the need for fire-resistant power cables is essential. LSZH cables provide a stable power supply while offering enhanced safety in case of fire, preventing electrical fires from spreading.

3.5 Data Centers

For data centers, where uptime and safety are crucial, LSZH power cables ensure that the electrical systems are both safe and efficient. These cables prevent fire hazards and minimize downtime during emergencies, providing a safe and reliable power source for critical IT infrastructure.

4. LSZH Cable Models and Specifications

The LSZH power cable comes in a range of models with different specifications, each suited to different applications. Here are some of the most common types:

· LSZH Cable (Basic Model): Suitable for general applications where minimal smoke emission and halogen-free properties are required.

· LSZH Cable with Steel Tape Armor (Model 23): This model is designed for environments that require additional mechanical protection, such as underground or industrial installations.

· LSZH Cable with Armored Design (Model 33, 43): These models are highly durable and suitable for harsh conditions, offering enhanced physical protection against external impacts.

5. Choosing the Right LSZH Power Cable for Your Application

When selecting an LSZH power cable, several factors must be considered to ensure the cable meets your specific needs:

· Voltage Rating: Ensure the cable’s voltage rating aligns with the requirements of your system (e.g., 0.6/1kV, 6/10kV).

· Environmental Conditions: Consider factors like temperature, humidity, and exposure to mechanical stresses when choosing the appropriate model.

· Safety Requirements: Depending on the fire risk and safety standards of your project, you may need additional features like steel tape armor or enhanced fire-resistant properties.
