Cable Type Comparison

BVR Cable

Multi-core copper wire, soft construction for easy installation, lower mechanical strength. Ideal for applications with slight movement requirements.

BV Cable

Single-core copper wire, rigid construction providing high strength. Suitable for fixed installations with minimal movement.

Comparison between BV and BVR cable types

Wire Selection Guide
