Coiled cables – also known as retractable cables, spiral cables or retractile cords – are engineered to extend and retract while maintaining reliable power or signal transmission. Their spring-like design allows them to stretch during use and return to a compact form when released, making them ideal for applications involving movement.
At Custom Designed Cables, we design and manufacture bespoke coiled cable solutions for industries where flexibility, durability and safety are essential. Used in medical equipment, military systems, vehicles and telescopic installations, high-quality coiled cables maintain performance without tangling, excess slack or mechanical strain.
If you require a custom coiled cable built to precise technical specifications, our team can help.
What is a coiled cable used for?
The primary purpose of a coiled cable is to provide flexible connectivity in environments with moving parts. Unlike straight cables, which can tangle or suffer damage under repeated motion, coiled designs expand and contract with the equipment.
This makes these cables particularly valuable in:
- Machinery with moving arms or joints
- Telescopic systems
- Medical devices requiring repositioning
- Vehicles and trailer interconnections
- Industrial production lines
Because the cable retracts automatically, it reduces clutter, improves safety and protects internal conductors from strain.
Key benefits of using a coiled cable
Retractable cables offer several practical advantages:
1. Exceptional flexibility
Depending on construction, a coiled cable can extend up to five times its original length. This flexibility allows continuous movement without conductor fatigue, making it suitable for dynamic applications.
2. Space-saving design
When released, the cable retracts into a compact spiral form. This is essential in restricted environments such as control panels, medical settings or complex machinery.
3. Reduced clutter and improved organisation
Unlike loose cables, coiled designs retract neatly, preventing tangling and trailing wires. This is especially important in fast-paced or safety-critical environments.
4. High durability
Professionally manufactured coiled designs withstand:
- Abrasion and repeated flex cycles
- UV exposure
- Chemical contact
- Moisture and environmental stress
Materials such as PVC, PUR, LSZH or Hytrel support reliable performance in demanding environments.
5. Enhanced safety
Because a coiled cable retracts rather than lying loose, it significantly reduces trip hazards. Its resistance to wear also lowers the risk of insulation failure or exposed conductors.
6. Time-saving
Automatic retraction removes the need for manual cable management, improving workflow efficiency in environments such as hospitals, manufacturing facilities and service vehicles.
7. Long-term reliability
Well-engineered coiled cables maintain electrical integrity after thousands of extension cycles. This reliability is critical in industries where downtime or equipment failure is not acceptable.
8. Versatility across industries
From medical imaging equipment to heavy-duty vehicle systems, designs can be customised for virtually any sector requiring controlled extension and retraction.
Common applications of coiled cable systems
Telescopic masts
One of the most common applications is telescopic masts. These structures extend vertically through sliding sections, requiring internal cabling that adjusts with movement.
Applications include:
- Surveillance and security systems
- Traffic enforcement vehicles
- Broadcasting and telecommunications
- Military communications
- Portable lighting towers
- Aircraft guidance systems
In each case, coiled cables ensure uninterrupted power or signal transmission during extension and retraction.
Medical machinery
Coiled designs are widely used in medical equipment such as:
- X-ray systems
- Defibrillators
- Pulse oximeters
In healthcare environments, reliability and hygiene are paramount. Medical-grade coiled cables must withstand repeated movement, sterilisation and cleaning chemicals while maintaining electrical performance. Its retracting design also reduces floor clutter, improving safety for both staff and patients.
Automotive and vehicles
The automotive sector relies heavily on coiled cables. Common uses include:
- Vehicle surveillance systems
- Assembly line equipment
- Electric vehicle charging equipment
- Trailer and articulated vehicle interconnections
In these applications, the coiled cable must endure vibration, environmental exposure and continuous mechanical stress. Custom conductor sizing and insulation materials ensure long-term durability in these environments.
Custom coiled cable manufacturing
Coiled cable performance depends on careful engineering. Key factors include conductor type, insulation material, coil diameter and retraction memory.
At Custom Designed Cables, we manufacture bespoke coiled cables tailored to your exact requirements, including:
- Extension lengths up to 30 metres
- Coil diameters from 5mm to 400mm
- Sheathing materials such as PVC, LSZH, PUR and Hytrel
- Custom jacket colours and printed branding
- Shielded or screened constructions for signal protection
Every coiled cable balances flexibility, tensile strength and electrical performance to ensure reliable operation across thousands of flex cycles.

Frequently asked questions
What is the difference between a coiled cable and a straight cable?
A coiled cable extends and retracts automatically, whereas a straight cable remains fixed in length. Coiled designs reduce strain, clutter and trip hazards in dynamic environments.
How long can a coiled cable extend?
Depending on design and materials, these cables can typically extend up to five times their retracted length. Custom designs can be manufactured for longer reach.
Are coiled cables suitable for outdoor use?
Yes. With the correct sheath materials, a coiled cable can be UV resistant, water resistant and chemically resistant, making it suitable for outdoor and industrial environments.r enquiry is, we can work with you on a solution within your deadlines and budget. Get in touch today for a quote!
