LSZH (Low smoke zero halogens) may be a low-smoke and halogen-free material, which implies that it's no halogen (F, Cl, Br, I, At), no lead, cadmium, chromium, mercury and other environmental substances, and can not emit toxic smoke when burned (such as Hydrogen halide, CO, dioxide, etc.) characteristics.
PVC (polyvinyl chloride), also referred to as vinyl resin, maybe a "self-extinguishing" and "flammable" substance.
LSZH could be a low-smoke, halogen-free material, environmentally friendly, and has good flame retardant properties, but its mechanical properties are poor, and therefore, the price is dearer. PVC contains halogen (chlorine), which can produce harmful gas when burned, making it unsuitable for indoor use. But its mechanical properties are better, and it's still employed in some less demanding occasions, and therefore the price is comparatively low.
LSZH may be a halogen-free material, non-toxic, with good flame retardancy but poor mechanical properties. PVC may be a halogen-containing (chlorine) material, which is flammable and produces intense and harmful gases when burned, but it's better mechanical properties.
To Then, allow us to discuss when to use one in all them.
In modern installations, any of them can and are equally effective, so as a cable expert, you're chargeable for understanding your situation and which situation are the simplest solution for this job.OLINK CABLE has 20 years of wiring harness production experience and a mature team of research and development.
LSZH has low smoke and flame retardancy, but it's expensive, but if your equipment is also exposed to high temperatures, or they'll cause a fireplace and cause other losses, then LSZH is suitable. It actually refers to confined spaces, like ships, airplanes, cars, elevators, submarines, hospitals, etc. In these places, fast communication is the key, but more importantly, safety is the key, so you would like to plan beforehand when designing the network.
It is also important that only LSZH cable sheaths are accepted within Europe because of European safety regulations. Within us, both forms of cables are accepted.
To On the opposite hand, after you install cables in a well-ventilated environment, you'll be able to use PVC. You recognize or are most confident that heat won't accumulate during this environment, usually utilized in long horizontal wiring or vertical communication between floors. Still, always aware To good ventilation and avoiding heat, you'll save lives by becoming innovative.
