Cable Gland Shroud
คุณสมบัติสินค้า:
The Shrouds are made from high grade polyvinyl chloride. The shrouds are used to increase the protection against external chemical and environmental agents of cable glands, specially on cable entrance. The significative reduction of dirt or foreign substances on the cable gland will facilitate the future maintenance of cable glands.

Technical Information :
What is the difference between LSZH, LSF and PVC ?
PVC Shroud (made of polyvinyl chilrode) 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.
Acronyms for low smoke zero halogen / halogen free include LSZH, LSHF, LSOH & OHLS . All these terms are interchangeable.
LSZH shroud are increasingly recommended for use in public buildings for increased fire safety in comparison to traditional PVC (polyvinylchloride). LSZH is often confused with LSF (low smoke & fume) but they are really very different!!
PVC Shroud :
Standard PVC is made up of a significant number of halogens which when burnt produce toxic gases including hydrogen chloride (HCL). Hydrogen chloride is extremely dangerous and corrosive, capable of causing serious harm to people and equipment. It can even be compared to mustard gas which is used as a chemical weapon. Standard PVC can produce around 28% HCL emissions if burnt.
LSF Shroud :
The term LSF only indicates that the shroud offers reduced smoke emission fire propagation compared with standard PVC. There is no standard governing the HCL emissions of LSF cagle but it will often produce between 18-220. HCL emissions when burnt which is still extremely hazardous.
LSZH Shroud :
The term zero halogen (interchangeable with halogen free) guarantees that if burnt the shroud will produce less than 0.5% HCL (hydrogen chloride) emissions. The standard sheathing material is fairly tough & flexible with resistance to a wide range of oils & chemicals.
Confusion sometimes arises due to the number of different terms in use within the industry for LSZH and the similarity of these terms to LSF. To add to this some manufactures of shrouds that are actually LSZH describe and even print them as LSF.
Another common misunderstanding is that LSF or LSZH shroud is also flame retardant or fire resistant, this is not necessarily the case and should be established separately if required. The term "flame retardant" inducates a shorud that will inhibit or slow the spread of fire. The term "fire resistant" indicates a shroud that will continue to operate in the presence of a fire. There are several recognised standards for flame retardance and fire resistance in shroud.
