Key Benefits of LSZH Bulk Wires
Low Smoke Emission: When exposed to fire, LSZH bulk wires produce significantly lower levels of smoke compared to PVC bulk wires. This reduces the risk of smoke inhalation and improves visibility in emergency situations.
Minimal Toxic Fumes: LSZH bulk wire emits minimal amounts of toxic fumes when subjected to fire, enhancing the safety of occupants in the vicinity.
Absence of Acid Gases: Unlike PVC, which release acid gases when burning, LSZH bulk wires do not emit acid gases.
Halogen-Free Composition: LSZH bulk wires are halogen-free, meaning they do not contain chlorine, fluorine, bromine, or iodine compounds. This makes them safer for human health and the environment.
These LSZH products provide greater safety compared to their polyvinyl chloride power (PVC) counterparts.

Frequently Asked Question
Unlike LSZH bulk wire, LSF bulk wires are manufactured using PVC compounds. If they are labelled as low-smoke and fume, it is due to the manufacturer modifying the compound with various additives to reduce (not eliminate) smoke and HCl emissions. However, where low smoke zero halogen bulk wires are subject to strict standards, there are no standards governing LSF bulk wires.
LSZH cables are eco-friendlier, emitting fewer pollutants during both their use and disposal. PVC cables, by contrast, release chlorine gas when burned, contributing to dioxin production and environmental harm.
