TPU spiral cable options | Compare TPU coiled cable applications
Quick answer: A custom 2-core TPU coiled power cable provides a compact, extendable connection for low-voltage equipment that moves during use. Nexharn Connectivity reviews conductor size, current requirement, retracted and extended length, connector design, TPU hardness, strain relief, testing and packaging before sampling. The final electrical rating and construction are confirmed according to the application rather than assumed from conductor count alone.

2-Core TPU Coiled Power Cable Product Overview
Two conductors are commonly used for positive and negative power paths in low-voltage DC equipment. The cable must still be engineered around real current, voltage, voltage-drop, movement and connector requirements. Coil geometry affects conductor stress, usable extension and return force, so a quotation should define both the relaxed dimensions and the normal working range.
Typical Applications
- Handheld equipment and industrial terminals
- Small power tools and portable work lights
- Vehicle accessories and low-voltage DC devices
- Charging docks and movable control units
- Compact equipment that needs an extendable power lead
Customization Options
- Conductor size and stranded copper construction
- Retracted length, working extension and coil outer diameter
- Straight tail length at each cable end
- Connector, open-end or overmolded termination options
- TPU jacket hardness, color and surface finish
- Logo, label, unit packing and export carton requirements

Cable Structure and Construction Options
Construction may use fine-stranded copper conductors, insulation selected for the electrical requirement, optional fillers, and a TPU outer jacket formed into a controlled coil. Connector ends may use molded strain relief or assembled protection depending on the termination. Conductor gauge, insulation system and jacket dimensions are selected after the equipment load and movement are reviewed.
Tradeoffs should be reviewed rather than hidden. Increasing conductor size or adding shielding may increase cable diameter and weight. A tighter coil can increase stress, while a longer extension can affect voltage drop, return force and service life. Nexharn confirms the proposed construction and sample acceptance plan before mass production.
Why TPU for This Application
TPU is considered when the cable is frequently handled, stretched or exposed to abrasion. Its flexibility and surface durability can be useful for portable equipment, but material grade and hardness must match the environment. A softer jacket may improve handling while a firmer formulation may support stronger rebound. Sampling is used to balance flexibility, coil memory and connector stress.
Testing and Quality Control
Test requirements and acceptance criteria are confirmed before sampling. Production inspection follows the approved drawing, sample and order specification.
- Continuity and polarity confirmation
- Conductor resistance or voltage-drop review when required
- Dimensional check for relaxed length, extension and tail lengths
- Stretch and rebound evaluation using agreed acceptance criteria
- Connector retention and strain-relief inspection
- Visual, label and packaging inspection before shipment
Information Required for Quotation
For an efficient engineering review, send the target application, wiring or pinout, electrical requirement, natural coil length, normal working extension, coil outside diameter, straight tail lengths, connector details, working environment, estimated quantity, packaging and destination market. A drawing is helpful but not mandatory; equipment photos, an existing sample or a dimensioned sketch can be used to begin discussion.

Buyer FAQ
Is every two-core coiled cable suitable for the same current?
No. Current capacity depends on conductor size, conductor construction, cable length, insulation, bundling, connector rating and operating conditions. The target load must be provided before quotation.
Can the connector and both straight tails be customized?
Yes. Connector type, orientation, molding, open ends and the straight length on each side can be reviewed during specification confirmation.
How should extended length be specified?
Provide the relaxed coil length, normal working distance and maximum expected extension. Designing only around a theoretical maximum can create excessive pulling force or poor recovery.
Can Nexharn match a sample cable?
A physical sample, clear photos or a dimensional drawing can be used as a starting point. Electrical and material requirements still need to be confirmed before approval.
What information is needed for a quote?
Share application, voltage and current, conductor gauge if known, relaxed and extended lengths, coil diameter, connector, quantity, testing and packaging needs.
