Zhong Hua Jiang 20AWG 3-conductor shielded drag chain cable is designed for compatible CNC machine-control wiring, industrial sensor connections and automation equipment that require three individually insulated conductors routed through a moving cable carrier. The cable is described as having twisted stranded tinned-copper cores, PVC insulation, a PVC outer jacket and a shielded construction for managing electromagnetic interference.
The published technical specifications identify a 300V voltage rating, an 80°C (176°F) temperature rating and an overall jacket diameter of 6.9 ± 0.3mm. Evaluate conductor count, operating current, cable run length, machine wiring diagram, environmental exposure and drag-chain movement before selecting a cable.
The specified construction contains three insulated, twisted tinned-stranded copper conductors within a PVC-insulated, PVC-jacketed shielded cable. The technical table also lists cotton rope and cotton paper as internal filling. Obtain the model-specific section drawing to confirm the overall screen construction, termination method and internal arrangement.
For OEM integration or replacement wiring, compare the number and function of each insulated core, identification colors, shield arrangement, gland or connector fit, electrical rating, permitted moving bend radius and equipment mounting environment.

CNC builders, industrial automation integrators, repair operations and distributors can evaluate this 20AWG × 3 shielded cable for compatible three-wire sensor and control connections that must travel in a flexible cable carrier.
An appropriately installed overall screen can help reduce electromagnetic noise coupled into sensitive control wiring. Use the CNC controller and electrical drive manufacturer’s recommendations for shield bonding and separation from inverter output leads. Do not treat the overall shield as an additional insulated conductor or a protective-earth replacement.
A useful purchasing inquiry identifies the 20AWG × 3 model, required cable or reel lengths, estimated quantity, machinery or sensor type, installation method, expected chain movement, operating voltage/current and any required drawings, reports or declarations.

| Oxidation Resistance | Low Eccentricity | High Conductivity | Insulation Resistant |
The published promotional images mention 15 million flex cycles. Actual durability depends on the tested model, dynamic bend radius, cycle speed, travel distance and installation conditions. Request applicable test records before specifying this figure in a machine design.
For moving cable systems, check the cable manufacturer’s allowed dynamic bending radius, minimum installation clearance, travel speed and strain-relief guidance. Jacket diameter alone does not establish the approved minimum bending radius.
The specified 6.9 ± 0.3mm outside diameter is relevant to cable gland sealing, connector entry and cable-carrier filling. Confirm the model drawing and movement specifications before finalizing the machine bill of materials.

The tinned-copper strands are intended for reliable conductive connections and practical solder termination. Tin plating can improve oxidation resistance at exposed strand surfaces when compared with bare copper.
The service life of a moving cable depends on the complete conductor, shield, filler and jacket construction, as well as its cable-chain installation and operating conditions.
For circuit design and voltage-drop estimates, request verified conductor-resistance data for this exact 20AWG model and calculate the electrical path length according to the actual sensor or controller circuit.
A correctly terminated cable shield can help limit coupled electromagnetic interference from nearby motors, drives and switching devices.
Follow approved controller grounding and shield-termination instructions. Keep sensitive low-level control wiring separate from higher-noise VFD power output circuits where the equipment design specifies separation.
The shield is an electromagnetic-interference control measure. Any protective-earth conductor must satisfy the machine wiring design and applicable standards independently of the screen.
Dynamic service requires more than a nominal flex-cycle statement. Check the machine carrier bend radius, travel speed and distance, installation temperature, cable separation and termination method with the tested cable’s documentation.
Discuss Cable Carrier Installation Requirements
The three insulated cores may be considered for compatible three-wire industrial sensor circuits, CNC control wiring and switching connections that call for a screened moving cable.
Potential applications include compatible three-wire position sensors, controller signal connections and related automation circuits inside CNC routers or moving machinery. Verify each pin assignment, voltage, load current, signal compatibility and safety requirement.
Three-core construction does not automatically qualify a cable for an encoder, motion-control feedback bus, RS-485 network or VFD-to-spindle motor output. Check device cabling requirements, cable impedance where applicable, shield design, conductor ratings and approved grounding.
For wholesale or OEM orders, share the three-core wiring schedule, requested length and packaging, number of machine assemblies, planned drag-chain movement, termination details, installation environment and any model-specific compliance documentation required.
Choose conductor count according to the actual terminal diagram, not just the cable diameter. A three-core screened cable has three insulated conductors; the external screen is not a fourth insulated conductor.
All three constructions refer to the number of separately insulated conductors. A three-core version may suit certain sensor supply, signal and return connections, subject to the equipment pinout. Select the number of wires required by the device and any separate protective-earth requirement.
| Cable configuration | Number of insulated conductors | Typical selection question |
| 20AWG × 2 | Two | Does the circuit use only two conductor paths? |
| 20AWG × 3 | Three | Does the approved device diagram require three conductor paths? |
| 20AWG × 4 | Four | Does the circuit require a fourth individually insulated path? |
The published overall cable diameter is 6.9 ± 0.3mm. Check connector entries, cable gland clamping dimensions, drag-chain cable compartment clearance and the manufacturer-approved dynamic bend radius.
The listed core colors are black, white, and yellow/green. Confirm this configuration on the approved core identification drawing. Where yellow/green is reserved for protective earthing under applicable standards, do not assign it to another circuit function.
For noise-sensitive CNC sensors, follow controller guidance for cable screening and bonding. Separate screened control leads from motor-output wiring as required. Confirm that the product is suitable for the intended signal standard rather than assuming shielding alone ensures compatibility.

It is a shielded electrical cable with three twisted 20AWG insulated tinned-stranded copper conductors and PVC insulation and jacket for compatible machine wiring.
The manufacturer-published outer diameter is 6.9 ± 0.3mm. Check the technical drawing for gland entry and cable carrier clearance.
The published technical table states 300V and 80°C (176°F). The installation and load-current requirements must be checked separately.
The published product specification lists 40.1 Ω/km at 20°C. Obtain a test record or an approved cable datasheet for this model before using that value in electrical calculations.
Black, white and yellow/green are listed. Confirm whether yellow/green denotes a striped conductor and verify the final wiring schedule.
Do not reassign it where yellow/green is reserved for protective earth by applicable wiring standards. Use the approved machine wiring design and the manufacturer’s core identification.
A three-core cable contains three insulated conductor paths instead of two. Choose the number required by the sensor or controller terminal diagram.
When the connection diagram requires four separate paths, choose an approved four-core construction rather than trying to use the shield as another conductor.
It is marketed for drag-chain use, but the approved dynamic bend radius, carrier travel, movement speed and tested construction should be verified for the exact order.
A numerical dynamic bending radius is not specified in the published table. Request an installation limit supported by the manufacturer’s documentation.
The product illustrations display this flex-cycle figure without defining its test conditions. Request the relevant test record before treating the figure as an expected service life.
Stranding improves cable conductor flexibility versus solid wire, while the tin coating can help with exposed-surface oxidation and solder termination.
An appropriately installed and bonded screen can limit coupled noise. Shielding effectiveness depends on termination, routing and the machine electrical environment.
No. It is not an additional insulated core and cannot automatically replace a protective-earth conductor required by the equipment safety design.
