What is the difference between rigid and flexible cable on Acti9 iC60, iSW, C120? Why they are of different size?

Flexible vs. Rigid Wires: The Key Differences.

Comparing Flexible vs. Rigid wire involves exploring the advantages and disadvantages of the two very different types of wire. A comparison narrows down the choices based on how the specific wire characteristics relate to their expected use and the project requirements. You must first determine your application’s requirements for weather resistance, flexibility, and resistance to splitting or severing. Then, choose the wire that most closely meets those needs.

The flexible and rigid cable is the preferred cable for iSW which accept both type of termination depends on users choice.

A flexible wire is a flexible wire, such as a multi-strand copper core wire, which has 20 to 30 sections on a 1.0 mm square section. It is used in places where frequent movement is required for excessive bending. It has strong oil, UV, water and abrasion resistance and is suitable for use in mobile and oily environments.

A rigid wire is a hard wire, such as a single-core copper wire or aluminum wire. It is not allowed to be excessively bent. It is often used for fixed laying. It has the advantage of easy to maintain shape and easy wiring. However, excessive bending or frequent bending is easy to break

Why there is size difference between flexible and Rigid copper wire

•Flexible vs. Rigid Wires wire current capacity.

Rigid wire is thicker, which means less surface area for dissipation. The thinner wires in stranded wire contain air gaps and greater surface area with the individual strands, translating to more dissipation. When choosing between rigid or flexible wire for wiring, the Rigid wire offers higher current capacity.
