1. Flame Retardant

The characteristic of flame retardant cable is to delay the spread of flame along the cable so that the fire does not expand. Because of its low cost, it is a variety of cables widely used in fireproof cables. Whether it is a single cable or a bundled laying condition, when the cable is burned, the spread of the flame can be controlled within a certain range, so it can avoid the Major disasters caused by cable fire and prolonged combustion, thereby improving the fire protection level of cable lines.

2. Halogen-free low-smoke flame-retardant cable (LSOH)

The characteristics of halogen-free low-smoke cables are that they not only have excellent flame retardant properties, but also the materials that constitute the low-smoke halogen-free cables do not contain halogens, so they have low corrosiveness and toxicity when burning, and produce a very small amount of smoke, thereby reducing the risk to the human body. , damage to instruments and equipment, is conducive to timely rescue in the event of a fire. Although halogen-free low-smoke flame-retardant cables have excellent flame retardancy, corrosion resistance and low smoke concentration, their mechanical and electrical properties are slightly worse than ordinary cables.

3. Low halogen and low smoke flame retardant cable (LSF)

The hydrogen chloride emission and smoke concentration indicators of the low-halogen low-smoke flame-retardant cable are between those of the flame-retardant cable and the halogen-free low-smoke flame-retardant cable. The material of Low Halogen cable also contains halogen, but the content is lower. The characteristics of this cable are not only flame retardant properties, but also release less smoke and hydrogen chloride during combustion. This low-halogen low-smoke flame-retardant cable is generally made of polyvinyl chloride (PVC) as the base material, and then processed with high-efficiency flame retardant, HCL absorbent and smoke suppressant. Therefore, this flame retardant material significantly improves the combustion performance of common flame retardant polyvinyl chloride materials.

4. Fire Resistant

Fire-resistant cables can maintain normal operation for a certain period of time under the condition of flame combustion, and can maintain the integrity of the circuit (Circuit Integrity). When the fire-resistant and flame-retardant cable is burned, the amount of acid gas smoke is small, and the fire-resistant and flame-retardant performance is greatly improved, especially when it is burned, accompanied by water spray and mechanical shock and vibration, the cable can still maintain the complete operation of the line
