5 Things to Look for When Choosing Low Smoke Zero Halogen Cable

Check now

Low smoke zero halogen cable (LSZH) is fantastic regarding safety and the environment. These heat-proof wire cables are designed to minimize smoke and toxic gas when exposed to heat or flames. That means they're perfect for places like buildings, tunnels, and airplanes where smoke inhalation can be hazardous. LSZH cables also have zero halogen content, so they don't contain those nasty halogen-based compounds that can harm the environment. After knowing the fascination of LSZH cables, how can we find the perfect low smoke zero halogen cable?

Process Performance

Do you want a low-smoke zero-halogen cable that's a breeze to install? It should be easy to handle, flexible enough to pass through tight spaces, and tough enough to resist wear and tear. No one wants a cable that falls apart or gives him a headache during installation.

Electrical Performance

Don't forget about the electrical stuff! Ensure the low smoke zero halogen cable you choose meets your application&#;s voltage rating, current-carrying capacity, and impedance requirements and prevents you from any power hiccups or performance issues down the line.

Mechanical Performance

A perfect low smoke zero halogen cable should be tough. With good tensile strength and crush, and impact resistance, it can handle all the bending, twisting, and pulling without a sweat.

Flame Retardant Performance

Here's where LSZH cables shine. They're designed to resist flames and prevent the spread of fire. Thus, when choosing LSZH cables, you must ensure they have excellent flame-retardant properties, looking for cables that meet important fire safety standards like IEC .

Environmental Performance

LSZH cables are eco-friendly superheroes. They don't contain those nasty halogen-based compounds that harm the environment and have a lower carbon footprint than regular cables. If you're an Earth-conscious consumer, choose a low-smoke-zero halogen cable from a manufacturer committed to sustainability.

Low Smoke Zero Halogen (LSZH) cables, also commonly referred to as ZHLS, 0HLS or halogen-free flame retardant (HFFR) cables, are manufactured for use in applications where the smoke and toxic fumes associated with PE and PVC cables could be harmful to people or sensitive equipment during a fire.

A shift in safety regulations across Europe has led to LSZH cables becoming increasingly favoured for specific settings. Let's take a closer look at why this is happening, how these cables work and the standards you need to be aware of when selecting an LSZH cable for your project.

How do LSZH cables work?

In a fire, a cable&#;s outer sheathing will begin to combust. When exposed to a flame, cables made of PVC compounds will produce vast amounts of dense black smoke, toxic fumes and acid gases. In poorly ventilated or underground spaces where escape routes might be obstructed by smoke, these fumes can become fatal.

LSZH cables are made of a flame retardant outer covering, meaning that their primary decomposition product will absorb the energy from the flame, diluting the fire gases. This causes a charring which acts as a fire barrier, so less smoke and chemicals are released when the cable is burned.

Changes in legislation: when and where to install an LSZH cable

Prompted by several major fire disasters, developments in LSZH legislation have been in motion for many years. The official investigation into the Kings Cross Station fire of confirmed that the majority of the disaster&#;s 31 fatalities were a result of PVC-related toxic fumes. A similar outcome was determined of the Dusseldorf airport fire, in which 27 deaths occurred.

As a result of these incidents, the use of PVC cables has been restricted across several European countries. Ireland, for example, has made the use of LSZH cables mandatory, linking to the Construction Products Regulations (CPR). Meanwhile, countries such as Switzerland, The Netherlands, Germany and Greece have made LSZH a legal requirement in high-risk environments such as evacuation routes and/or high-rise buildings.

Whilst most cable types will now be available with LSZH sheathing, each installation must be considered on its own merits. In order to offer low smoke, zero halogen properties, the jacket of an LSZH cable uses a high percentage of flame retardant additives (fillers). This can impact properties such as flexibility, chemical and water resistance &#; so bear this in mind when weighing up the needs of your project.

Which standards should LSZH cable buyers look out for?

For a cable to be verified as LSZH, it must undergo a series of performance and compliance tests to ensure it meets European and international standards. Here are some of the key standards and testing procedures that cable buyers should seek to confirm their cables are in compliance with.

IEC/EN -1/2 specifies a smoke density test performed inside a 3-cubic metre chamber. While burning PVC has been found in testing to reduce light visibility to 10% (i.e, the thickness of the smoke obscures overall vision by 90%), certified low-smoke cables will have a minimum light transmittance of 60%. In the event of a fire in an enclosed space, this ensures that escape routes remain unobstructed and in reasonably clear view.

IEC/EN -1 stipulates that emissions of the highly toxic, acid gas hydrogen chloride (HCI) by LSZH cables must not exceed 0.5%. When PVC is burned, as much as 30% of emissions released can be HCl. To certify a cable as LSZH, a testing process sees 1g+/-0.005g of cable insulation material placed in a tube furnace and heated to 935ºC for 30 minutes. The gases produced are absorbed into a catch solution, which is then made up into a litre of liquid.

Following a similar process, IEC -2 measures the pH of the solution and tests its conductivity values. Low Smoke Zero Halogen materials are defined as having a pH no less than 4.3 and a conductivity not exceeding 10µS/mm.
