Selecting the ideal jacket material for a fire-resistant cable is critical for ensuring safety, performance, and compliance in any application. The three primary options—PVC, LSZH, and Teflon®—each offer distinct properties. PVC is a cost-effective, durable choice for general use; LSZH (Low Smoke Zero Halogen) is essential for enclosed public spaces where minimizing toxic smoke is paramount; and Teflon® provides unparalleled resistance to extreme temperatures and harsh chemicals, making it ideal for the most demanding industrial environments. Understanding their differences is the first step toward specifying a cable that guarantees operational integrity and protects both people and property.
