There has been a recent surge in the popularity of and requirements for Low Smoke Zero Halogen (LSZH) cable. Uses have evolved from the origin of LSZH cables (old Mil-Spec for Shipboard cables) to the transportation and infrastructure sectors. The need for LSZH cables is based upon the physical characteristics. LSZH cables are flame retardant and most importantly do not generate toxic gas. Increasing regulations at the local, state and government levels regarding flame and smoke requirements has led to the usage of LSZH cables.
The hallmark of LSZH cables are excellent flame resistance, low smoke production and low toxicity in the event of a fire. Many of the compounds used to manufacture cables (PVC, FEP, and many more) contain a high concentration of halogens like chlorine and flourine. When burned, they created very toxic and corrosive gases that can damage or destroy organic or inorganic substances alike. Through engineering advancements, compounds have been created that have both excellent mechanical and electrical properties, as well as achieve the desired flammability and toxicity characteristics. LSZH has become more widely used since its original inception in the military, and later, transportation markets. Its traits make it applicable to uses in the utility market, computer and data centers, and highly populated buildings such as skyscrapers, hospitals, arenas, and hotels.
