Difference Between Power Cables & Control Cables

Cables are of various types and varieties, with each cable designed to perform a specific function. The performance and durability of cables depend on the quality of its raw materials. Each individual cable has a distinguished construction, which differentiates it from others.

Power and control cables are often confused for one another, but there are certain elements of each cable that set them apart.

Control cables as their name suggests, send signals to control the functioning of equipment. This type of cable allows distribution of data or signals that have low voltage. They are designed specifically for automation controls, with a copper conductor that is enveloped in galvanised steel braid.

One similarity the two cables have is the variety of cables available in their product range. Control cables have a number of specifically designed cables suited to various automation and computer applications. They are generally twisted in pairs and possess a balanced shielding that reduces interference.

Power cables on the other hand transfer both high energy and low energy from the source to the equipment. They are specifically designed to best suit active and neutral environments and bear a thick outer sheath compared to ordinary control cables. The external sheath of power cables, coupled with its great strength and protection enables the cables to transfer high volume of energy without any tension or strain.

Power cables in comparison to control cables, have a unique colour code system that distinguishes the high voltage carriers from their low voltage counterparts. Control cables on the other hand offer superior resistance to interference, making them the ideal cable for sending low voltage signals.
