Flexible Cables: The Ultimate FAQ Guide

1. What is Flexible Cable?

Flexible cable is a cable whose manufacturing takes into account the physical stress and tight bending which is common in moving applications.

They are also known as continuous cables.

2. What are the Benefits of Flexible Cables?

The benefits of  marine flex cable include?

  • Reliability as they fit special parts of an electrical equipment.
  • They offer space effectiveness as they can fit as close to each other as possible
  • Their flexibility allows them to easily bend to fit a particular condition
  • They are relatively lightweight as they use fewer materials
  • They are fire retardant
  • They have a wide range of usage

3. Where can you use Flexible Cables?

You can use flexible cables in the following areas:

  • Pendants
  • Connecting portable appliances and lamps
  • Wiring fixtures
  • Elevator cables
  • Connecting portable signs
  • Connecting fixed equipment
  • Data processing cables
  • Temporary wiring
  • Wiring hoists and cranes
  • Preventing vibration or noise

4. Are there Disadvantages of Flexible Cable?

The disadvantages of flexible cable include:

  • It is relatively expensive when you compare it to other types of cables.
  • Flexible cables are less durable due to their applications. this increases the overall replacement cost of flexible cables.

5. Types of Flexible Cables are there?

There are two types of flexible cables depending on the arrangement of the conductors.

  • Stranding conductors in layers which is relatively cheaper
  • Stranding conductors in bundles which involves braiding the conductors on a tension-free center.

6. Which Material is Flexible Cable made of?

Flexible consists of the conductor material and insulation material.

The conductor material can be:

  • Copper material.

Copper is the best conductor material for flexible cable due to its high conductivity rate.

Due to its malleability, copper easily bends making it the best alternative to use in flexible cables.

Also, copper has a high heat resistance which eliminates overloading issues.

However, copper is limited as a conductor since it has a high probability of electromagnetic interference.

  • Optical fibre

It is an alternative conductor material as it is not affected by electromagnetic interference.

The insulating material can be:

  • PVC material

The advantage of PVC material as an insulation material is that it is a flame-retardant material.

It is a lightweight material which means it does not add weight on the overall flexible cable.

  • Fibreglass

Fibreglass is an excellent insulating material as it has minimal heat transfer capability.

It is also a non-flammable insulating material with a low R-value.

7. How does Unarmoured Cable compare to Flexible Cable?

Both unarmoured cable and flexible cable do not have the extra protection which is associated with the armoured cable.

The unarmoured cable can either be a flexible or straight cable.

The unarmoured cable is relatively expensive when you compare to flexible cables.

Flexible cables have a wide range of applications when you compare to unarmored cables

8. Armoured Cable vs. Flexible Cable; How do they Compare?

You can use armoured cables in locations that are subject to mechanical damage such as outside walls.

The extra protection in armoured cables gives it an edge over flexible cables in terms of application areas.

Flexible cables are relatively cheaper when you compare to armoured cables

9. Are there Standard Sizes for Flexible Cables?

No. there are no standard sizes for flexible cables.

The size of a flexible cable depends on your requirements.

We also customize flexible cables depending on your specifications.

10. How do you Test the Quality of Flexible Cables?

There are a number of tests that flexible cables have to go through to determine their quality. they include:

  • Continuing test measures the resistance of the flexible cable
  • Insulation test determines the resistance test of the insulation material
  • Phasing test which takes place on all live wires of the cable
  • Flexibility test analyzes flexibility level of the cables
  • Voltage test analyzes how much voltage the flexible cable can handle
  • Earth resistance test determines the resistance

11. Do Flexible Cables have a Number of Core Limits?


there is no limit as to the number of cores a flexible cable can have.

There are different flexible cables with different core numbers such as single, double and triple flexible core units.

12. What are the Characteristics of Flexible Cable?

The characteristics of flexible cables include:

  • Flexibility

The flexibility nature of these cables allows for their use in applications that have a high level of stress and minimum space.

  • Versatility

You can use flexible cables in a wide range of applications. this includes electronics, machines and automotive.

  • Wide range of operating temperature

Flexible cables offer a wide range of operating temperatures.

This allows for the use of these cables in applications with high heat requirements.

  • Heat resistance

Flexible cables have a high heat resistance rate when you compare to other cables.

It is this characteristic that suits them for their use in moving industrial applications

13. Flexible Cables come in how many Color Coding?

Flexible cable color coding

 Flexible cable color coding

There is a wide range of color coding for flexible cable depending on the region one is coming from.

However, most color coding in different regions takes into account yellow, red, green and black as their main colors.

14. Is there a difference between Flexible Cable and Flexible Cord?

A flexible cord refers to a flexible cable that cross-sectional of the conductor is less than 6mm square.

A flexible cable is a cable that can easily stretch or bend depending on the application’s needs.

Flexible cables usually contain conductors that have been insulated together to form one unit.

A flexible cord consists of different conductors each having separate insulation.

15. How does Flexible Cable compare to Non-flexible Cable?

Flexible cables are ideal for moving applications while non-flexible cables are suitable for fixed installation.

Flexible cables are usually stranded whereas non-flexible cables are solid core cables which are not stranded.

The manufacturing cost of a flexible cable is relatively higher when you compare to no-flexible cable.

Non-flexible cables are durable when you compare to flexible cables.
