Flexible Power Cable Types, Benefits and Features

Flexible power cables are cables that are designed to carry electrical power in environments where there is frequent movement or bending. 

 

These cables are commonly used in applications involving constant movement and flexing, such as power tools, welding equipment, and machinery.

 

An old telephone wire that used to twist and provide users with flexibility when pulled is the best example of flexible wire.  

Flexible power cables are typically made up of several layers of materials, each serving a specific purpose. 

Design

Flexible power cables are designed in such a way that they can bend and flex without damaging the cable or compromising electrical performance. 

 

A high strand count of conductors is typically used in the design, allowing the cable to bend and flex more easily. 

 

Furthermore, the insulation and outer jacket are typically designed to be highly flexible and long-lasting, allowing the cable to retain its flexibility even after repeated use.

 

Why choose flexible power cables?

 

Increased service life

A cable inside a cable carrier with a higher level of flexibility has a longer service life.

 

A standard cable can handle 50,000 cycles, whereas a flex cable can handle between one and three million cycles.

Manufacturing is simple 

Cables are typically less expensive because they are simple to manufacture. Stranding in layers will be a much easier process during copper flexible cable production.

 

These cables are designed in such a way that they can be distinguished from standard designs. 

 

These cables are also known as chain-suitable, high-flex, or continuous-flex cables. They are designed to handle the tight bending radius as well as the physical stress associated with it.

 

Much less expensive

Tight-stranded cable cores are left for many of the centre layers and are enclosed in a tube-shaped jacket. In the case of shielded cables, the cores are wrapped in foil or fleece.

Adequate Elasticity

The inner radius is compressed and the outer radius is stretched during the bending process. 

 

The flexible copper wire can function properly because the elasticity of the elements is sufficient.

 

Only when the material is fatigued will performance deformations occur. When the cores begin to move, their own zones of elasticity begin to form, which aid in stretching and compressing activities.

 

This activity will cause the core to rupture in a corkscrew shape.

 

There are two types of flexible copper wire available. They are stranded in layers of conductors and cables with bundled or braided conductors.

Each conductor has a uniform bend radius

Other construction techniques will be used when braiding conductors. Instead of layering, this technique will involve the conductors circling a tension-free centre.

 

Eliminating the multi-layers ensures a uniform radius of bend across each conductor.

 

The cores' path will move quickly from inside to outside from one end to the other. The single core never stretches at the outside bends and never compresses near the inside bends.

 

Efficiency of Space

The cables are designed in such a way that they will fit together tightly wherever they are required. As a result, the cables may use the unoccupied space. Because there is no dead space available, the overall cost of laying down the cables will be reduced.

Dependability

These cables are designed to meet specific requirements for fulfillment and are completely reliable in terms of operation. The materials used also uphold the standards and efficiently perform any specific settings.

Extremely light in weight

When you use flex cables, the weight of the wire is reduced. To perform efficiently, these cables may use minimal materials. 

 

Several Uses

The cables are used in both residential and industrial settings. Flexible multicore cable is ideal for use in electrically powered machines like refrigerators, air conditioners, and motors.

 

These wires are much more flexible and offer the best protection all year. Even under extreme stress, they do not begin to heal and continue to work efficiently.

 

Flexibility and Strength

The tensile load is shared equally by insulators and conductors, and flexible electrical wire has a high 

strength. 

 

Uses of flexible power cable

 

Flexible power cables are used in a variety of applications that require flexible, long-lasting, and dependable power transmission. Some common applications for flexible power cables include:

 

Flexible power cables are frequently used in industrial machinery like conveyor systems, robots, and automated manufacturing equipment. The cables are designed to withstand the constant motion and vibration that occurs during operation and are used to transmit power to the machinery.

 

Flexible power cables are frequently used with portable power tools such as drills, saws, and grinders. The cables are lightweight and flexible, making them easy to maneuver and use in confined spaces.

 

It also used with construction equipment such as cranes, excavators, and trenchers.

 

Things to keep in mind when choosing a flexible power cable

Here are some more details on the factors to consider when choosing flexible power cables for a specific application:

 

Voltage rating

A cable's voltage rating is the maximum voltage that it can safely handle without breaking down or posing a hazard.

 

The manufacturer usually specifies this rating, which is usually printed on the cable.

 

It is critical to select a cable with a voltage rating that matches the voltage of the electrical system with which it will be used.

 

Using a cable with a lower voltage rating than the system voltage can cause the cable to overheat, potentially resulting in a fire or an electrical shock.

Current rating

A cable's current rating is the maximum amount of electrical current that it can safely carry.

 

The manufacturer typically specifies this rating, which is usually printed on the cable. It is critical to select a cable with a current rating that matches the application's current demands.

 

Using a cable with a lower current rating than the application requires can cause the cable to overheat, potentially resulting in a fire or electrical shock.

 

Environmental conditions

When choosing a flexible power cable, it is critical to consider the environment in which the cable will be used.

 

Cables that are resistant to water, sunlight, and temperature fluctuations may be required for outdoor applications.

 

Cables with chemical-resistant insulation and outer jacket materials may be required in corrosive environments.

 

Cables with special insulation materials that can withstand high temperatures may be required in high-temperature environments.

 

Flexibility requirements

When choosing a flexible power cable, consider the flexibility of the cable.

 

The cable must be flexible enough to accommodate the application's movement and bending without damaging the cable or compromising its electrical performance.

 

The cable's design, including the number of conductor strands and the materials used for insulation and the outer jacket, can influence its flexibility.

 

Safety standards

To ensure that a flexible power cable is safe for use in the intended application, it must meet relevant safety standards. Underwriters Laboratories (UL) and Canadian Standards Association (CSA) standards ensure that the cable has been tested and meets specific safety requirements. 

 

Choosing a cable that meets these specifications can help ensure that it is safe to use in the intended application.

 

Installation and maintenance

Proper installation and maintenance of flexible power cables are critical to ensuring their safe and dependable operation. 

 

The cable should be installed according to the manufacturer's instructions and kept safe from physical damage and excessive heat or moisture. The cable can be inspected and maintained on a regular basis.
