What You'll Learn
Coiled cords have many applications
Coiled cords, also known as retractile or curly cords, have a wide range of applications due to their unique properties. They are designed to stretch and recover to their original length, offering added length during use and saving space when not in use. This makes them ideal for various applications where flexibility and space optimisation are crucial.
One of the key advantages of coiled cords is their flexibility. The spiral jacket, made from insulating materials like thermoset or thermoplastic resins, allows the cord to extend and retract while minimising stress on the wire. This flexibility is especially useful in applications where constant movement is involved, ensuring that the cord can move with the equipment without restricting its range of motion.
Coiled cords are also valued for their space-saving capabilities. Their self-retracting nature eliminates the need for manual winding, saving time and effort. The compact nature of coiled cords also helps prevent tangles, further enhancing their space-saving benefits. This makes them ideal for applications where space is limited or where cord management is a priority.
The insulating jacket of coiled cords provides another layer of protection for the wires within. It safeguards the wires from scratches, spills, and moisture. Additionally, the jacket can be made from heat-resistant materials, allowing the cords to be used safely in harsh environments with high temperatures. This feature makes coiled cords suitable for applications where exposure to extreme conditions is a concern.
Coiled cords also find applications in electronics, robotics, and medical arenas. They are used in communication devices, industrial equipment, and military applications. The ability to customise coiled cords in terms of size, shielding, and materials makes them adaptable to a diverse range of uses. For example, the use of a heat-resistant, flexible spiral jacket makes retractile cords safe for use in harsh environments, while the choice of insulating materials can provide protection from oil, solvents, and flames, making them suitable for military applications.

They are made of metal wires
Coiled cords, also known as retractile or curly cords, are made of metal wires. The wires are typically made of copper or aluminium. These metals are flexible and can be coiled without losing their durability. The metal wires are then encased in a spiral jacket, which is usually made from an insulating material like thermoset or thermoplastic resins such as PVC. This outer jacket is crucial as it helps protect the wires inside from moisture, scratches, and spills.
The metal wires within the coiled cord provide the necessary conductivity for electrical applications. Copper and aluminium are excellent conductors of electricity, making them ideal for this purpose. The conductivity of these metals ensures that electrical signals or power can be transmitted efficiently through the cord.
The coiled design of these cords offers several advantages. Firstly, it provides flexibility and stretchability. The coils allow for extension, giving additional length when needed. This feature is particularly useful when a power outlet is located far from the equipment. Secondly, the coiled design saves space. The compact nature of the coils means that the cord takes up less room when not fully extended.
Coiled cords come in various sizes, from short cords used in phone chargers to extra-thick cords for industrial and military applications. The size of the coiled cord is chosen based on its intended use. Customization options are also available, where the length, jacket, and conductor colours can be tailored to specific requirements.
The metal wires within coiled cords can be shielded to protect against electromagnetic interference (EMI). This shielding is important in certain applications where interference from other electrical power sources could be an issue. The shielding is created by adding one or more thin layers of metal or a braided mesh woven into the wires, acting as a barrier against electromagnetic energy.

They are encased in a spiral jacket
Coiled cords, also known as retractile or curly cords, consist of metal wires encased in a flexible, spiral jacket. The wires are usually made of copper or aluminium, while the spiral jacket is typically made from an insulating material like thermoset or thermoplastic resins such as PVC. This insulating jacket protects the wires from scratches and spills, and the material helps protect the wires inside from moisture.
The spiral jackets also allow the cords to stretch, providing additional length when needed. For example, if a power outlet is too far from your equipment, the stretchable coil cord can provide the necessary reach. This feature makes them space-saving and convenient.
Depending on their intended use, coiled cords can be customised with different connectors and components. They come in various sizes, from short cords used in phone chargers to extra-thick cords for industrial and military applications.
It is important to note that while the insulating jacket provides physical protection, it does not shield the wires from electromagnetic interference (EMI). If protection from EMI is required, shielded variants of coiled cords should be used. Shielding is made from cable metal, typically copper or aluminium wire, and it acts as a barrier against electromagnetic energy, minimising noise from other electrical power sources.

The jacket is made from insulating material
Coiled cords, also known as retractile or curly cords, are commonly seen in hospitals and homes. They are made of metal wires, usually copper or aluminium, encased in a flexible, spiral jacket. This jacket is made from an insulating material, such as thermoset or thermoplastic resins, with PVC being a common example. The insulating jacket serves as protection for the wires inside, shielding them from scratches, spills, and moisture.
The insulating material used in the jacket's construction plays a vital role in maintaining the integrity and functionality of the coiled cord. By selecting suitable insulating materials, such as thermoset or thermoplastic resins, the jacket can effectively safeguard the internal wires from various forms of damage. This protective barrier ensures that the coiled cord remains durable and reliable over time.
The jacket's insulating property is particularly important in providing scratch resistance. The jacket forms a protective layer around the delicate metal wires, preventing them from being scraped or damaged during regular use or when coming into contact with surrounding objects. This scratch resistance helps maintain the structural integrity of the coiled cord, ensuring that it remains functional and safe for its intended purposes.
Additionally, the insulating jacket helps protect the coiled cord from spills. Whether it's water, coffee, or any other liquid, the jacket's material is designed to repel or resist absorption, preventing the liquid from reaching the internal wires. This spill protection is essential in maintaining the electrical safety and functionality of the coiled cord, especially in environments where spills may occur, such as in kitchens or laboratories.
While the insulating jacket offers excellent protection against physical damage and moisture, it's important to note that it does not provide shielding against electromagnetic interference (EMI). If protection from EMI is required, shielded coiled cords are available, which utilise cable metal shielding, typically made of copper or aluminium wire, to minimise electromagnetic energy interference.
In conclusion, the insulating material of the jacket in a coiled cord is crucial for maintaining the cord's performance and longevity. By safeguarding against scratches, spills, and moisture, the jacket ensures that the internal wires remain intact and functional. However, for applications requiring EMI protection, shielded variants of coiled cords are necessary.
