FAQ: LSZH vs PVC

The difference between LSZH and PVC cable coating often brings many questions.
Customers ask: why should I use LSZH or why should I choose for PVC?

Most of our customers choose PVC, because it is cheaper than LSZH cables.
You might think now: "So LSZH has already lost the competition", but there are some great advantages to LSZH cable coating!

What do the terms "LSZH" and "PVC" even mean?

LSZH means: Low Smoke Zero Halogen.
PVC means: Polyvinyl Chloride. PVC molecule model

What is the difference between the two?

The physical differences are very distinct. A polyvinyl cable feels very soft and is smooth, while an LSZH cable feels rough and is stiffer.
However the advantage of the LSZH cable comes with heat. When a PVC cable is set on fire, it emits chemical fumes and acids -which is not very healthy for your personnel-.
Whereas an LSZH cable does not emit these chemical substances.
This means that the LSZH cable meet the health and safety standards. Not every new building requires these health and safety standards though and the peformance of both cables remains the same.

So when do I use LSZH or PVC?

Both cables are excellent in performance, so it depends on the situation whether you choose LSZH or PVC.
If the health and safety demands fire proof cables, you need LSZH. If not, you are safe with PVC cables.
