What distinguishes LSZH cable from PVC cable?

What distinguishes LSZH cable from PVC cable?

When a PVC cable (made of polyvinyl chloride) burns, its jacket releases hazardous fumes, hydrochloric acid, and a lot of black smoke. The jacket of Low Smoke Zero Halogen (LSZH) cable is flame-resistant and does not release any harmful gases when it burns.

Where are LSZH cables used?

LSZH cables are often utilized in big public venues where there is a risk of fire since its main function is to reduce risk from the after-effects of an electrical fire, such as gas and smoke inhalation.

What distinguishes LSZH from halogen-free standards?

A halogen-free cable is usually composed of polypropylene, which doesn't release any hazardous gases or acids when it burns. The following terms are frequently used to describe cables meant to perform this kind of function: Low Smoke Zero Halogen, or LSZH.

Why should I use zero-halogen low-smoke cable?

A low-smoke zero halogen cable discharges smoke at a slower rate and with reduced optical density when it burns. A low-smoke cable is preferred during a fire because it lessens the quantity and density of smoke, making it simpler for people to escape a building and improving the safety of firefighting operations.

If my cable is halogen-free, how can I tell?

The skin burning method is used to identify low-smoke, halogen-free cables. Iron the low-smoke, halogen-free cable's insulating layer without any visible depression using a soldering iron. A significant depression indicates a flaw in the insulating layer's composition or application technique.

Are wires devoid of halogens required?

The current European Standard DIN EN 45545-2 establishes the specifications for rail car fire prevention. It stipulates that all wires have to be free of halogens, flame-retardant, self-extinguishing, and unable to spread fires.

When was the last time rubber cable was used?

The majority of household cables were tough rubber sheathed (TRS) until pvc-insulated cables gained popularity in the 1960s.

What benefits do rubber cables offer?

Rubber cables are particularly well-suited for use as trailing leads for portable electrical appliances, power tools, pumps, and generators in severe settings because to their exceptional resilience to abrasion and weathering. Rubber cables are also designed to offer superior resistance against various chemicals and lubricants.

Is rubber cord resistant to UV light?

The insulated rubber cable is ideal for a variety of outdoor settings because it is flexible, waterproof, UV-resistant, and able to withstand temperatures ranging from -20°C to 60°C.

What sets LSF and LSZH apart from one another?

Although LSF cables are a more affordable option than standard PVC cable, they can nevertheless release a significant amount of smoke and hazardous gas. LSZH is the highly advised choice in places with a high risk of fire or high population density.
