When should I specify LSZH over PVC for control cable insulation?

This is a critical safety consideration for the international market:

PVC (Polyvinyl Chloride): The industry standard for general industrial use. It is cost-effective, flexible, and resistant to many chemicals. However, it releases toxic halogens and thick smoke during a fire.

LSZH (Low Smoke Zero Halogen): Mandated for use in public buildings, data centers, and poorly ventilated areas. In the event of a fire, LSZH cables produce minimal smoke and no corrosive acid gases, protecting both human life and sensitive electronic equipment.
