Introduction of Electrical Control Cable

An Electrical Control Cable is a multi-conductor cable used to send control signals, measurement and regulation in automation systems. They are commonly used in transport, building, mining and industry applications.

Unlike power cables, control wires do not need the same sheathing and are usually insulated with conventional PVC. They are often color coded to indicate the positive and negative wires.

Power vs Control Cable

There are several differences between power and control cables, including voltage, conductor sizes and construction. Most power cables transfer a larger amount of electricity than control cables.

In addition, power cables use a variety of core structures and shielding measures to prevent electromagnetic interference. They also have a higher rated voltage of 0.6/1kV and above, while control cables are mainly 450/750V.

Aside from these differences, both types of cables are similar in construction and usage. Both are typically made from XLPE, PVC, PE, single and multi-conductor, sheathed or steel-wire armored, jackets and more.

In the field of process automation, there are three main types of control cable. They are CY, YY and SY cables. YY and CY control cables are regular unshielded cables, while SY control cables feature GSWB braid for mechanical protection.
