What Is Concentric Cable?

A concentric cable is a special type of low voltage power cable consisting of an insulated central conductor surrounded by one or more layers of helically arranged metallic conductors.

The concentric layer normally works as:

• Neutral conductor
• Earth conductor
• Protective grounding conductor

Compared with traditional single-core cables, concentric cables provide:

• Improved electrical safety
• Reduced installation complexity
• Better protection against electrical faults
• Cost-effective power connection solutions

Sitong Cable manufactures different types of concentric cables according to conductor material, voltage rating, and application requirements.
