Final Thoughts
The choice between LSF, LSZH, and PVC for electrical wiring solutions depends on various factors, including the specific application, regulatory requirements, and budget constraints.
LSF and LSZH cables prioritize fire safety by minimizing smoke and toxic emissions, making them ideal for environments where human safety is a paramount concern.
