PVC is commonly used in cable insulation and wire jacketing to regulate cable current and create a safe exterior that does not provide its own risk. External PVC layers on electric lines and cables are required for electrical safety and reliability. The added protection they give shields conductors from dirt, moisture, and corrosion, allowing electric wires to last longer without creating a severe health or safety risk.

When it comes to electrical safety, PVC is renowned to be self-extinguishing in the event of a fire or overheating. While PVC can catch fire from a variety of causes, it contains self-extinguishing qualities that make it fire resistant. All sources of fire will be extinguished by the material, and it will not continue to burn. The material is also difficult to ignite, which means it won’t catch fire readily in the event of overheating.
