Was sind die Vor- und Nachteile von raucharmen, halogenfreien Kabeln??

Ich weiß nicht, wann das Konzept des grünen Umweltschutzes tief in den Herzen der Menschen verankert ist, sei es aus Nahrungsmitteln oder dem täglichen Bedarf, Immer mehr Menschen entscheiden sich für umweltfreundliche Produkte. Even the decoration wire is no exception – low smoke halogen-free cable.

This type of cable has good environmental performance and high practical performance. Heute, ZMS cable editor will take you to understand the low smoke halogen-free cable.

Low-smoke halogen-free cable is a material classification of wire sheaths in the cable industry.

Low smoke represents the low concentration of smoke emitted when the sheath is heated. Halogen-free represents the non-release of halogen-containing gases during combustion. Low smoke halogen-free cable in the combustion will only produce a light water mist and does not release hydrogen chloride or other acids. And the maximum operating temperature is up to 150 ℃

Advantages of Low Smoke and Halogen-Free Cables

Halogen-Free

The use of green insulation layer, Mantel, and special oxygen barrier materials, not only has good electrical properties, physical and mechanical properties.

And to ensure that the product does not contain halogen, to solve the “secondary pollution” formed when it burns, and to avoid the traditional PVC wire burning toxic substances.

Low Smoke and Low Toxicity

A new type of special covering material that is non-polluting to the environment is used, and no toxic gas is generated during production, use, and combustion. And very little acid gas is emitted, reducing the harm to personnel and equipment.

It is very necessary to use raucharme, halogenfreie Kabel for the occasions where the personnel is concentrated in particular.

Environmental Friendliness

Insulation and sheath do not contain lead, Cadmium, and other heavy metals harmful to human beings. The use of cable and waste disposal will not cause pollution to the soil, or water, compared to traditional cable more environmentally friendly.

Low-smoke halogen-free cable is also known as environmentally friendly cable, so it is still very friendly to the environment.

High Flame Retardant

Environmental protection cable to ensure its high fire requirements of the building requirements. The cable is not easy to burn in case of fire and can stop the spread of flame and disaster after burning.

Especially in modern construction appear super high-rise buildings and modern material products, and when a fire occurs, increases the difficulty of rescue.

The use of a low-smoke halogen-free cable can increase rescue time and reduce the harm of harmful gases to humans.

LSZH cable disadvantages

The disadvantages of low-smoke halogen-free may be the price and the use of popular aspects.

Although low-smoke halogen-free cables are friendly to the environment, their raw materials and technology costs are more expensive than ordinary PVC-type cables.

And because ordinary PVC, polyethylene cable has excellent electrical conductivity, and mechanical. And some other excellent performance, low smoke halogen-free cable can not yet completely replace ordinary cable, so the use of popularity is not too widespread.

Momentan, low-smoke halogen-free cables are more and more widely used in high-rise buildings, Stationen, and subways. Airports, Krankenhäuser, large libraries, gymnasiums, Einfamilienhäuser, Hotels, Krankenhäuser, Bürogebäude, Schulen, Einkaufszentren, und andere überfüllte Orte. I believe that with the improvement of people’s awareness of fire prevention. Jinhaotai’s low-smoke halogen-free cables will be more and more used in our lives.

The difference between LSZH Cable and Flame-Retardant Cable

The difference is mainly in the cable outer sheath material.

Halogen-free low-smoke flame retardant cable insulation layer, Mantel, with better flame retardant properties, the cable smoke generation is also small, and less toxic.

The price of halogen-free, low-smoke flame retardant cable is higher.

1 Flame retardant cable is in the specified test conditions, the specimen is burned, after the withdrawal of the test fire source. The spread of flame only within the limits, the residual flame or residual burn in the limited time can be the self-extinguishing cable.

Its fundamental characteristic is that it is possible to be burned in case of fire and cannot operate. But the spread of fire can be stopped. Laienhaft ausgedrückt, the cable, in case of fire, can be limited to the local scope of combustion. Not to produce the spread of a variety of other equipment to preserve, to avoid causing greater damage.

2 Halogen-free low smoke flame retardant cable insulation, Mantel, Außenhülle. And auxiliary materials (tape and filling) are all or part of the halogen-free cross-linked polyethylene (XLPE) flame retardant materials, not only have better flame retardant properties. But no halogen acid gas is released when the cable burns.

The amount of smoke generated by the cable is also small. And the corrosive gas generated by the burning of the cable is also a compromise between the flame retardants of the cable and the reduction of the amount of halogen acid gas occurrence. And a low-halogen, low-smoke flame retardant cable has been developed. Its halogen content is about 1/3 of that of halogen-containing flame retardant cables. The amount of smoke generation is also close to the accepted “low smoke” level.

What are the models of halogen-free low-smoke cables?

Halogen-free low-smoke cables are commonly used in low-smoke halogen-free power cables and low-smoke halogen-free control cables. And low-smoke halogen-free home furnishing wires. Divided into two categories of low-smoke halogen-free flame retardant cables and low-smoke halogen-free flame retardant, feuerbeständige Kabel.

Low-smoke halogen-free cable use places

1 High-rise residential building in the open cable, a class of high-rise buildings, and important public places.

2 Large and medium-sized shopping malls, large transport buildings (Flughäfen, Stationen), and large and medium-sized stadiums.
