| Low smoke zero halogen cables provide a lot of great safety advantages, but there is a bit of an electrical and mechanical trade-off. In order to be low smoke zero halogen, the cable jacket must incorporate a high percentage of filler material. This increase in filler material could make the jacket less chemical and water resistant and could provide poorer mechanical and electrical properties than a non-LSZH counterpart. LSZH jackets are also more likely to experience jacket cracking during installation, so special lubricants may be necessary to avoid damage. This is especially true in cold environments. Because of the limited flexibility of LSZH, it is not recommended in robotic or continuous flex applications. As a result, LSZH cable is commonly chosen for applications where fire safety is more of a concern than the cable’s specific electrical and mechanical properties. Advances in compound materials and processing have decreased some of these issues. |
