They are therefore often specified indoors, especially in public areas, and in other hazardous environments and poorly ventilated areas. This includes cars, aircraft, railway carriages and ships. LSZH sheathed cables are commonly used across tunnels and underground rail networks.
Does LSZH need cable?
When burned, a low-smoke zero halogen cable emits a less optically dense smoke that releases at a lower rate. During a fire, a low-smoke cable is desirable because it reduces the amount and density of the smoke, which makes exiting a space easier for occupants as well as increases the safety of firefighting operations.
Can LSZH cable be used outdoors?
AFL's Indoor/Outdoor Low Smoke Zero Halogen (LSZH) Breakout Cables are perfectly suited for rugged applications and installations requiring increased performance. These cables feature a durable IEC-compliant, zero halogen, UV and fungal resistant outer jacket.
Is LSZH better than PVC?
Judging from the physical appearance, the difference between LSZH and PVC cable is very distinct. A PVC cable feels soft and it is smooth, whereas an LSZH cable feels rough since they contain the flame retardant compound and it is stiffer. LSZH cables are more aesthetically appealing than PVC cables.
What material is LSZH?
Low-Smoke Zero-Halogen (LSZH or LSOH) is a type of plastic used in the wire and cable industry for cable jacketing. LSOH cable jacketing is custom compounded to produce minimal smoke and low toxicity when exposed to fire.
Is polypropylene a LSZH?
Low smoke zero halogen, or LSZH, refers to using compounds in the cable jacketing manufacturing process that are halogen free. Halogen free cable, on the other hand, is made up of a compound called polypropylene, which will not produce a toxic smoke during combustion.19 Mar 2008
What is LSZH wire?
LSZH cable/wire refers to cables where the cable jacketing and insulation is made with materials that produce low/limited smoke and non-toxic halogens when exposed to fire or high temperatures. There is also low smoke cable and zero halogen cable / halogen free cable.
Does LSZH contain PVC?
What's the difference between PVC and LSZH cables A PVC cable (made of polyvinyl chloride) has a jacket that gives off heavy black smoke, hydrochloric acid, and other toxic gases when it burns. Low Smoke Zero Halogen (LSZH) cable has a flame-resistant jacket that doesn't emit toxic fumes even if it burns.
What does LSZH stand for?
Low Smoke Zero Halogen
Which cables is fire retardant?
The definition of a fire-resistive or fire-rated cable is a cable that will continue to operate in the presence of a fire. This is commonly known as a circuit integrity (CI) cable and is 2-hour fire-rated. Mineral Insulated (MI) cable has provided this added protection for decades.
What are two types of fire resistant cables?
- Single Core Enhanced Circuit Integrity.
- Draka FT Fire Resistant Fibre Optic Armoured.
- Prysmian FP200 Gold Fire Alarm Cable.
- Draka FT Fire Resistant Fibre Optic Unarmoured.
- Draka FireTuf OFC-LT-NM Fire Resistant Loose Tube Fibre Optic Cable Non-Metallic Armoured.
