Low smoke zero halogen (LSZH or LSOH) is a material classification typically used for cable jacketing in the wire and cable industry.LSZH cablejacketing is composed of thermoplastic or thermoset compounds that emit limited smoke and no halogens when exposed to high sources of heat (ie. flame).

Most network cables are insulated with polyethylene, PVC or Thermoplastic Urethane (TPU) . In fires, a halogen-containing plastic material releases hydrogen chloride, a poisonous gas, which forms hydrochloric acid when it comes in contact with water. Designated Halogen-free cables, on the other hand, does not produce a dangerous gas/acid combination or toxic smoke when exposed to a flame. Low smoke zero halogen cable reduces the amount of toxic and corrosive gases emitted during combustion. These types of materials are typically used in poorly ventilated areas such as aircraft or rail cars. Low smoke zero halogen is becoming very popular and in some cases a requirement in instances where the protection of people and equipment from toxic and corrosive gasses is critical.

Fires on board vessels can produce toxic gases and heavy smoke. Our marine low smoke, zero halogen cable can minimize the effects from these dangers. Save lives, protect your equipment from damage, and meet specifications that require use of LSZH cable. This cable is a low-cost alternative to the military spec cable often used in commercial applications.

Low Smoke Zero Halogen (LSZH) cables or low smoke & fume (LSF) cables is used in applications such as Central Offices, Mass Transit Rail Systems, Nuclear Plants and Oil Refineries or in any other application where the protection of people and equipment from toxic and corrosive gasses is critical. Low Smoke Zero Halogen cable is often lighter, so overall cable network system weights can be reduced and the environmental impact of halogen free cabling can be lower if there are fewer toxic chemicals.

In summary, the LSZH cable has four ascendant performance, as follows:

Superior overall performance of the one: On environmental cracking phenomenon. Products in use when cracking occurred, seriously affect the service life of the cable. The environmental cracking phenomenon is a complex issue affected by many factors. Generally that is closely related to the causes and products processed LSZH sheath of residual stress, phase interface debonding and resin hardening and embrittlement.Fiber optic manufacturerIngellen supplies breaking elongation of greater than 200% and extraordinary aging properties to overcome this phenomenon provides a useful. Superior overall performance of the two: The outstanding thermal deformation properties the hold when heated smallest nature of the thermal deformation undoubtedly has its value in use. Under conditions of heat stress experiments show that up to 90 ° C or 100 ° C standard. Moreover, in the not pressed condition under the heat deformation properties are more prominent. Free Hanging conditions such as 120 ° C after 240 hours the same, while a large number of similar products mud off and was soon heat only 3-4 hours. Superior overall performance of the three: High flame retardant Low Yat smoke performance to meet IEC 1034 standard.

Superior overall performance of the four: Available for different user to select a wide range of rheological properties.
