Flexible Cable Types and Benefits:

When To Avoid Use of Flexible Cables

Just as there are many kinds of equipment and gadgets, there is also much kind of cables to charge

them. A cable has to not just meet equipment’s requirements; it must also suit the environment in

which it functions. This is why we have flat cables, battery cables, instrumentation cables and flexible

cables.

Flexible cables are used where we need a cable that can be moved around. These are cables that can

bend under an external force without any resultant damage to their physical integrity. Some cables

have higher flexibility than others. Flexible cable manufacturers supply to a wide array of industries

— from music to marine instruments in machines that are as diverse as crane, speakers and

conveyors! The rising automation has increased the demand for flexible cables, since most

automation solutions require cables that can cope with constant movement and have the capability to

stay intact for long.

construction broadly speaking there are two types

Construction

Broadly speaking there are two types of flexible cables: those with conductor stranding in layers, and

those with bundled or braided stranding.

Bundled or braided stranding:

Here the conductors are braided around a tension-proof centre. By avoiding layering and putting the

conductors in a tighter bundled construction, we create more uniform bend radius for each conductor.

At the point of the flex, the core moves from the inside towards the outside. This is a quick movement

and it guarantees that the compression and stretch of the cores is not confined to a single core. The

pressure is uniform, reducing the overall stress. The insulation is usually pressure filled, since the

intention is simply to keep the cores from unwinding. This makes the braided cables stiffer than

layered cable. But it has a longer flex life.

Stranding in layers:

Here the flexible cable manufacturer will have cores that are stranded in layers around a centre.

The cores are left in relatively long strands. The insulation is a simple extruded jacket. The

construction means that the pressure on the conductors is more unevenly distributed as the inner

radius compresses, but the outer radius is stretched. This gives the cable more flexibility as the inner

cores bend easily. But over time, the inner and outer cores get set in their stretching zones. Material

fatigue sets in and the cable gets deformed. So, even though it has higher flexibility, its flex life is

actually lower.

Why do we need flexible cables?

Finely stranded:

Flexible cables typically have fine stranding which gives them their flexibility.

Durable insulation:

A flexible cable must have a tough and durable insulation to withstand the constant bedding and

coiling. This also makes it suitable for all kind of environments. Most insulation jackets are able to

withstand the usual number of corrosives.

Variety of sizes:

These are available in all kind of sizes. This is mostly because flexible cable manufacturers have to

cater to a wide range of machine and implements. It means that whatever you requirements, you will

find a cable for it.

custom built many flexible cable manufacturers

Custom built:

Many flexible cable manufacturers will offer custom built cables to meet the unique requirements of

a particular instrument. IN many cases, the cables have to be used with specific connectors. Many

manufacturers will also offer custom built connector, giving you an entire range of custom built

construction.

Can pass flex tests?

Only a flexible cable can pass a flex test with flying colours. While many cables may withstand

bending for an initial installation, only flexible cables will have the flex life to sustain prolonged

movement.

Things to keep in mind when selecting with flexible cables:

Flexible cables require the right fittings, connectors. The selection must also take into account

the unique functioning, ampacity etc. All these factors must be calculated and considered

beforehand.

Each cable has its place. While flexible cables have multiple benefits, as listed below, rigid

cables have their own place and one must never mix the two. Do not use a flexible cable where

you need a permanent wiring. The cables, designed to have movement will be difficult to install

and stay installed!

A damaged or deformed cable is a fire hazard waiting to happen. Replace such cables, instead of

patching them up.

Flexible cable manufacturers today have a wide range of cables categorized by type and function.

Talk to your supplier to know more about what you need.
