Why Choose LSZH Compounds?

If you seek further insights, please visit SUNUA.

The industrial demand for Low Smoke Zero Halogen (LSZH) cables is on the rise. This heightened interest primarily stems from safety concerns related to both individuals and electronic devices during fires. Additionally, the growing emphasis on environmental conservation and increasing local and global standards have driven the necessity for LSZH cables.

This growing recognition of the adverse impacts of halogens when subjected to flames has culminated in the development of these specialized cable jackets.

Understanding LSZH

LSZH is an acronym for Low Smoke Zero Halogen, representing a category of insulation and jacket materials devoid of halogens. Terms such as LSOH, HFFR (Halogen Free Fire Retardant), and NHFR (Non Halogenated Fire Retardant) frequently appear as synonyms within this context.

Insight into Halogens

Halogens are elements known for their tendency to form unstable compounds because they lack one electron. Consequently, they are highly reactive and tend to bond with other elements to achieve stability. These elements can react with metals, resulting in salt formation; for instance, table salt is derived from the halogen chlorine combined with sodium. Furthermore, their reaction with water can yield acids, such as hydrocholoric acid, produced from hydrogen and chlorine.

Halogens in Flame Retardancy: A Necessity?

In some polymers, incorporating a halogen atom can enhance flame-resistant properties. A common example is Poly-Vinyl-Chloride (PVC), which contains chlorine that, upon combustion, is released to displace oxygen from the fire, thus suppressing the flames. Some flame-retardant variations of polyethylene also include bromine to aid in fire protection.

The Dangers of Halogens in Fires

When halogens combine with hydrogen, they produce harmful acids that can threaten both flora and fauna. Chlorine exemplifies a halogen whose properties are utilized under control to disinfect water, eliminating pathogens and bacteria. In earlier practices, iodine-based solutions served similar purposes.

Examining PVC

The combustion of PVC results in the release of chlorine, which can then combine with hydrogen to create corrosive acids. Such acidic byproducts pose serious health risks, potentially harming the respiratory systems and eyes of those escaping from a blaze. They can also damage undamaged equipment even months after an incident. Historical evidence indicates that devices several rooms or floors away from a minor fire may fail later because of damage inflicted by halogenated acids or residues.

Advantages of LSZH Cables

By using LSZH compounds, which lack halogens, these cables utilize the release of water or other harmless substances to extinguish flames. This trait makes them significantly safer for individuals and the environment.

Applications of LSZH Cables

LSZH cables can be employed similarly to conventional cables. However, they are especially advantageous in indoor or confined settings due to their reduced toxicity in fire scenarios. Thus, they are frequently utilized in tunnels, offices, data centers, and exchange sites.

Are LSZH Cables Compatible with Green Star Credits?

Absolutely! LSZH cables meet Green Star application standards. They represent the safest option for plenum spaces and other scenarios where smoke accumulation endangers individuals, as they do not release harmful toxins. In alignment with sustainable practices and minimizing environmental impacts, Madison Express expands its eco-friendly range with Low Smoke Zero Halogen cables provided by Garland.

What is LSZH (Low Smoke Zero Halogen)?

LSZH indicates a cable type crafted from materials that emit minimal smoke and forgo halogen emissions during combustion.

These cables are engineered to mitigate the release of toxic gases and halogenated substances, thus decreasing health and ecological risks during burning.
