5. About custom Lszh cable

As mencioned above, CE LiHH is an cavo di controllo made of halogen free material, so it belongs to LSZH cable.

Low smoke zero halogen or low smoke free of halogen is a material classification typically used for cable jacketing in the wire and cable industry. LSZH cable jacketing is composed of thermoplastic or thermoset compounds that emit limited smoke and no halogen when exposed to high sources of heat.

 

6.Description of LSZH cable

Low smoke zero halogen cable(lszh cable) considerably reduces the amount of toxic and corrosive gas emitted during combustion. When burned, a low-smoke zero halogen cable emits a less optically dense smoke that releases at a lower rate. During a fire, a low-smoke cable is desirable because it reduces the amount and density of the smoke, which makes exiting a space easier for occupants as well as increases the safety of firefighting operations. This type of material is typically used in poorly ventilated areas such as aircraft, rail carriages, tanks, subsea and offshore installations, submarines or ships. It is also used extensively in the rail industry, wherever high voltage or track signal wires must be run into and through tunnel systems. The nuclear industry is another area where LSZH cables have been and will be used in the future. Major cable manufacturers have been producing LSZH cables for nuclear facilities since the early 1990s. Construction of new nuclear plants will almost certainly involve extensive use of LSZH cable. This will reduce the chance of toxic gases accumulating in those areas where personnel are working and the lack of corrosive gases where there are computer controlled systems will reduce the possibility of wires being damaged by fire resulting in a short circuit fault.

Several fires, such as the King’s Cross fire in London that killed 31 people in London’s underground in 1987, increased the awareness of the contribution that wire and cable jacketing makes in a fire. As a result, there has been an increased use of LSZH cables. With an increase in the amount of cable found in residential, commercial and industrial applications in recent years, there is a greater fuel load in the event of a fire and LSZH systems have a major role to play in protecting the public.

7. How to make a custom lszh cable?

To create a custom LSZH cable, the cable manufacturer will typically work with the customer to understand their specific requirements, including the intended application, the environment in which the cable will be used, and any regulatory requirements that must be met. The manufacturer will then design a cable that meets these requirements and provide a quote for the custom cable.

The cable itself may be constructed using a variety of materials, including copper or fiber optic strands for the conductive portion of the cable, and LSZH materials for the jacket and insulation. LSZH materials are typically made from thermoplastic polymers that are low in smoke and free from halogens, which are chemicals that can be hazardous to health when burned.

Overall, the process of creating a custom LSZH cable involves careful planning, design, and testing to ensure that the cable meets the customer’s needs and performs reliably in its intended environment.

8.LSZHcables and PVC cables

The European market is demanding that cables used in LANs, WANs, etc. meet LSZH specification. The IEC 60332-1 governs the Flame Retardant Grade specifications in reference to LSZH cables.

Reduction of dangerous/poisonous gases

Essentially, the compound used in manufacturing cables meeting the above specification reduces the amount of dangerous/poisonous gases in case of fire. The main difference in specifications between IEC 60332-1 versus UL® 1581, UL 1666 and UL 910 is that the cable under the IEC spec can continue to burn while still emitting very low gases. The UL specs demand that the flame be extinguished, but it can still emit dangerous/poisonous gases.

IEC specification

Today virtually all medium and large installations in Europe must meet the IEC specification. Many public authorities are already demanding that new installations must meet IEC 60332-3 which is a more demanding flammability specification for LSZH. IEC 61034 for smoke emission is part of all Black Box LSZH bulk cables.

What’s the difference between PVC and LSZH cables

Physically, PVC and LSZH are very different. PVC patchcords are very soft; LSZH patchcords are more rigid because they contain the flame retardant compound, and they are aesthetically more pleasing

A PVC cable (made of polyvinyl chloride) has a jacket that gives off heavy black smoke, hydrochloric acid, and other toxic gases when it burns. Low Smoke Zero Halogen (LSZH) cable has a flame-resistant jacket that doesn’t emit toxic fumes even if it burns.

LSZH more expensive and less flexible

LSZH cables usually cost more than the equivalent PVC cable, and certain types are less flexible. LSZH cable does have some restrictions. According to CENELEC standards EN50167, 50168, 50169, screened cables must be halogen free. However, no similar regulation yet applies to unscreened cables.

Where do you run the cable?
Whether you choose a riser (PVC), plenum or LSZH jacket depends on where you’re going to run the cable.

PVC cable is commonly used for horizontal runs from the wiring centre. You can use it for vertical runs between the floors – but only if the building features a contained ventilation system running through the duct work.

LSZH cable is used between floors in a building. It has a special flame-retardant coating.
