Low smoke zero halogen cable, also known as LSZH, LSOH, LS0H, LSFH, and OHLS, belongs to the category of wire sheathing materials. It is made of halogen-free thermoplastic or thermosetting materials, and produces low smoke and does not release toxic gases such as hydrogen chloride when burning.

Many customers search through numerous suppliers, only to return to us in the end. Why? Because in the LSZH (Low Smoke Halogen-Free) field, cheap options are everywhere, but truly reliable products that give engineers, supervisors, and owners peace of mind are rare.

When buying LSZH cables, the three biggest fears are:

• Black smoke upon welding, exceeding halogen limits upon testing: Despite being advertised as halogen-free, halogen content exceeds limits during acceptance, or smoke density is so high you can’t see your hand in front of your face, causing the entire project to fail acceptance. This not only results in financial losses but also damages your reputation.
• Cracking with bending, breaking easily with pulling: Many manufacturers use incorrect material ratios, making cables brittle like cookies in winter and sticky like putty in summer. Workers complain during installation, and later maintenance becomes a nightmare.
• Delivery time is always a mystery: When you’re chasing delivery, you’re the boss; after payment, they become the boss. Project deadlines are dragged out, and you have to bear the penalties for late delivery yourself.
