Wires and cables are essential components of power and information transmission systems, and low-smoke, zero-halogen (LSH) wires and cables have become a key type widely used in construction, communications, and other fields. These cables produce less smoke and hazardous gases in the event of a fire, making them crucial for personnel safety and equipment protection. The following is an introduction to the main categories of LSH wires and cables:
1. LSH Power Cables:
LSH power cables are primarily used for power transmission within buildings. They typically include the following types:
1. N2XH Cables: N2XH cables are a type of LSH power cable suitable for power distribution systems within buildings. These cables produce minimal smoke and hazardous gases in the event of a fire, helping to improve evacuation safety.
2. NHXH Cables: NHXH cables are another type of LSH power cable widely used for power transmission within buildings. They meet LSH standards, reducing fire risks.
2. LSH Communication Cables:
LSH wires and cables are also widely used in communication systems to ensure the safety of information transmission equipment in the event of a fire. The main types include:
1. LSZH Communication Cable: Low-smoke, zero-halogen communication cables are typically made from low-smoke, zero-halogen materials, such as low-smoke polyethylene (LSZH). They are widely used in data centers, office buildings, and other locations requiring data transmission.
2. FEP Communication Cable: Polytetrafluoroethylene (FEP) cable is a high-performance, low-smoke, zero-halogen cable suitable for high-temperature environments and specialized applications, such as aerospace.
3. Other Low-smoke, Zero-halogen Wire and Cable:
In addition, there are several specialized types of low-smoke, zero-halogen cables, including:
1. Low-smoke, zero-halogen optical fiber cables: These cables are commonly used in data centers and communication networks to ensure the safety of fiber-optic equipment in the event of a fire.
2. Low-smoke, zero-halogen control cables: These cables are suitable for control systems and automation equipment, ensuring control system reliability in the event of a fire.
Low-smoke, zero-halogen wire and cable are a critical cable type, primarily designed to reduce the generation of smoke and hazardous gases in fire situations, improving personnel safety and equipment protection.
