3-Core TPU Coiled Power Cable

TPU spiral cable options | Compare TPU coiled cable applications

Quick answer: A custom 3-core TPU coiled power cable can support equipment that requires three conductors for power, grounding or an additional control path while maintaining a compact retractable form. Nexharn Connectivity develops the cable around the actual circuit, conductor size, coil dimensions, connector, movement, testing and packaging requirements. Voltage, current and safety suitability are confirmed for each construction and are not inferred from the number of cores.

3-Core TPU Coiled Power Cable Product Overview

Three-core constructions may be selected for line-neutral-ground arrangements in an appropriate system or for low-voltage power plus an additional signal or control path. These are different electrical uses and must not be treated as interchangeable. A buyer should provide a wiring diagram or clear pin assignment so the conductor colors, connector terminals and inspection method can be agreed before sampling.

Typical Applications

• Industrial equipment and movable machine controls
• Cleaning equipment and mobile workstations
• Power tools and workshop accessories
• Work lights and adjustable electrical equipment
• Devices requiring a grounding conductor or auxiliary control conductor

Customization Options

• Three-conductor color code and wire gauge
• Grounding or control-conductor identification
• Relaxed coil length, working extension and return force
• TPU jacket grade, hardness, color and markings
• Connector pin assignment and strain-relief design
• Label, packaging and destination-market documentation needs

Technical Specifications

Cable Structure and Construction Options

The construction can include three flexible stranded conductors with application-specific insulation, fillers or separator where needed, and a TPU outer jacket heat-set into a coil. The conductor lay, cable outside diameter and coil diameter influence flexibility and recovery. Connector exits should be oriented to reduce twisting, especially when the equipment moves repeatedly.

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 can provide a useful combination of flexibility, abrasion resistance and coil recovery for industrial handling. Selection still depends on oil exposure, cleaning chemicals, temperature, pulling frequency and surface requirements. Where grounding or mains-related use is involved, conductor identification, component suitability and required compliance documentation must be reviewed for the destination market.

Testing and Quality Control

Test requirements and acceptance criteria are confirmed before sampling. Production inspection follows the approved drawing, sample and order specification.

• Continuity, pinout and grounding-conductor verification
• Electrical tests agreed for the intended circuit
• Dimensional inspection of coil and straight tails
• Working-extension and rebound evaluation
• Connector retention and cable-exit inspection
• Packaging check to prevent coil deformation

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

Does three-core automatically mean the cable is suitable for AC mains power?

No. Suitability depends on conductor, insulation, jacket, connector, voltage, current and applicable market requirements. The complete construction must be reviewed.

Can one conductor be used for a control signal?

It may be possible, but the circuit, noise environment and electrical separation requirements must be provided. A shielded or different construction may be more appropriate.

Can conductor colors be customized?

Conductor identification can be reviewed according to the wiring diagram and applicable requirements. Custom jacket colors and external marking are also available for discussion.

How do you control coil recovery?

Coil diameter, pitch, cable OD, TPU formulation, heat-setting process and working extension all affect recovery. Samples should be approved using an agreed stretch-and-return method.

What should an RFQ include?

Include wiring diagram, voltage, current, grounding requirement, connector, conductor gauge, coil dimensions, movement, environment, quantity and packaging.

MOQ and Lead Time

MOQ is quoted after the conductor construction, TPU grade, connector, tooling, testing and packaging are reviewed. Sample and production lead times are estimated after the drawing revision, material availability, quantity and approval route are confirmed. Request written project terms; no fixed MOQ or delivery promise applies to every custom cable.

Testing and Custom-Option Resources

For project-specific test methods, equipment and acceptance records, review TPU cable testing and quality equipment. Use the RFQ, sample approval and packaging worksheets to describe custom conductor, connector, coil geometry, shielding, labels and pack options before quotation.
