Zhong Hua Jiang 20AWG 2-conductor shielded drag chain cable is designed for compatible CNC machine-control circuits, industrial sensors and automated equipment that require two insulated conductors in a flexible cable-carrier run. Twisted stranded tinned-copper conductors, PVC insulation, and a shielded cable construction help organize two-wire connections in space-constrained machinery.
The product specifications list a 300V voltage rating, an 80°C (176°F) temperature rating and a 6.4 ± 0.3mm outside diameter. Select the cable based on equipment wiring diagrams, operating current, installation length, ambient exposure and movement requirements.
Two stranded tinned-copper insulated conductors are arranged in a flexible shielded construction with PVC insulation and a PVC outer jacket. The published technical table also identifies cotton rope and cotton paper as internal filling. Confirm the exact shielding type and construction using a manufacturer-approved cross-section drawing.
For replacement wiring and OEM production, compare the conductor cross-section, two-core color identification, shield construction, jacket dimensions, connector or cable gland, minimum moving bend radius, and the equipment’s voltage and current requirements.

For CNC builders, machine-integrators and industrial distributors, this 20AWG two-core cable offers a candidate for compatible low-current machine-control connections, sensor circuits, switch wiring, and moving cable-carrier routes where shielded wiring is needed.
The cable shield may reduce coupled electromagnetic interference when correctly bonded and installed. Route sensitive sensor and controller leads separately from inverter motor-output power cables where the equipment design calls for separation. The shield is not a third insulated core or a substitute for protective earth.
When requesting a quotation, identify the 20AWG × 2 construction, black-and-white core identification, cable lengths, total quantity, circuit voltage and current, cable-chain movement, termination type and any requested technical or compliance documents.

| Oxidation Resistance | Low Eccentricity | High Conductivity | Insulation Resistant |
The product graphics refer to 15 million flex cycles. This advertising value does not establish service life in every cable carrier; request the actual test method, bend radius, travel distance and tested product reference before specifying flex life.
Select an approved cable-carrier bend radius from the exact cable construction and manufacturer documentation. The correct bend radius also depends on dynamic travel, acceleration, clearance, strain relief and operating environment.
The published outer diameter of 6.4 ± 0.3mm helps with cable gland, connector and drag-chain clearance selection. Confirm real production dimensions, jacket compatibility and minimum dynamic bend radius before making the final installation drawing.

The stranded tinned-copper conductors offer conductivity and practical solder termination while tin plating can improve oxidation resistance at exposed strand surfaces.
Flex performance depends on conductor construction, shield design, jacket composition, installation conditions and the application’s bending cycle.
For voltage-drop calculations, request the verified 20AWG conductor resistance and use the complete out-and-return conductor length for the actual circuit.
A correctly installed cable shield helps limit unwanted electrical noise coupling into nearby low-voltage control and sensor wiring.
Follow the controller and machine manufacturer’s guidance for shield termination, conductor routing, protective earthing and separation from VFD output leads.
Cable shielding is an electromagnetic-interference control measure, not a replacement for a required protective-earth conductor or machine safety connection.
The supplier’s promotional images mention 15 million flex cycles, but no test-bend radius or laboratory conditions are given in the main specification table. Qualification for a moving installation should use the operating stroke, speed, acceleration, strain relief and confirmed mechanical test conditions.
Discuss Drag-Chain Requirements
20AWG two-core shielded cable can be considered for suitable CNC control circuits, switching devices, sensors and automation wiring that use two conductor paths.
Typical application evaluations include CNC router limit or position switches, compatible sensor power or signal lines, and controller circuits routed through a moving drag chain. Confirm the actual pinout, load current, noise level and required safety protection.
Two 20AWG insulated wires do not automatically meet the needs of a differential bus, encoder cable, motor-output power circuit or a safety-rated stop system. Confirm pair structure, impedance, loading, grounding and relevant device requirements before substitution.
For bulk or OEM supply inquiries, provide the complete two-wire schematic, conductor colors, required length per assembly, order volume, connector type, drag-chain travel, environmental conditions, packaging and documentation needs.
Confirm whether the circuit requires two insulated conductors. Cable shielding is a separate construction element and must not be counted as another signal or protective-earth core.
For the same copper material and conductor length, the larger 18AWG cross-section ordinarily gives less resistance than 20AWG; 22AWG has the smaller cross-section. Confirm the diameter, shield construction, cable current limits and bending requirements of the specific options.
| Gauge and core count | Relative conductor size | Selection consideration |
| 22AWG × 2 | Smaller than 20AWG | Compact two-core control wiring when current and voltage drop permit |
| 20AWG × 2 | Intermediate size | Two-wire control or sensor circuits using the specified 20AWG construction |
| 18AWG × 2 | Larger than 20AWG | Potentially lower resistance if the approved cable dimensions and movement suit the machine |
The supplied 20AWG two-core cable table lists a 6.4 ± 0.3mm overall jacket diameter. Confirm cable entry dimensions, gland grip range, drag-chain clearance, minimum dynamic bend radius and strain-relief design using the manufacturer-approved cable drawing.
The two conductor colors are identified as black and white. These colors do not establish polarity, safety ground or sensor pin assignment without the device wiring schedule. Keep screen termination separate from the internal conductor identification.
For noise-sensitive sensor or controller connections, follow the machine supplier’s screening, bonding and cable-routing guidance. Verify the actual 20AWG resistance and total loop length before calculating voltage drop or using the cable for a load-bearing circuit.

Huajiang began with CNC spindle motor production in 2000 and expanded into CNC machines, VFDs, accessories and electrical cables. The Zhong Hua Jiang brand was established in 2018 for international markets.
It is a two-core cable with 20AWG twisted tinned-stranded copper conductors, PVC insulation, a PVC jacket and shielding for suitable low-voltage machine wiring.
The published specification lists 6.4 ± 0.3mm. Check the production drawing for connector entry, cable gland choice and drag-chain compartment sizing.
The supplied table identifies a 300V rating and a temperature rating of 80°C (176°F). Equipment circuit loading must still be assessed for the installation.
The published technical table lists 13.7 Ω/km at 20°C. Ask for a test report or corrected technical sheet identifying this specific 20AWG cable before relying on the value.
The published colors are black and white. Follow the approved wiring diagram to assign voltage, return, signal or any other circuit functions.
20AWG generally has a larger copper cross-section than 22AWG, giving lower electrical resistance at the same length. Verify each cable product’s actual specifications, jacket diameter and installation limits.
18AWG has a larger conductor than 20AWG. It may suit a different loading or voltage-drop requirement, but jacket size, movement and equipment compatibility must also be checked.
The cable is presented for moving cable-carrier use. Confirm permissible dynamic bending radius, stroke, travel speed and installation conditions for the exact model.
The published cable specifications do not state a model-specific minimum dynamic bend radius. Ask for a rated value instead of calculating one solely from outside diameter.
Promotional graphics cite 15 million cycles, but the test setup and model-specific conditions are not provided. Ask for the test report before using that number as a design requirement.
Stranded copper provides flexibility relative to a similarly sized solid conductor, while tin plating helps with solderability and oxidation resistance. Total cable performance still depends on the shield and jacket.
With correct installation and termination, shielding may reduce electromagnetic interference coupled into compatible machine-control signals. Effectiveness depends on the electrical environment and grounding arrangement.
No. Treat the signal cable screen separately from any protective-earth conductor required by the machine electrical safety design.
Do not assume this cable is suitable for a VFD motor-output circuit. Select a motor cable using the drive and motor current, voltage, EMC and earthing requirements.
It may be evaluated for suitable two-wire sensor and switch connections. Confirm voltage, load current, polarity, signal type, connector pinout and approved cable specifications.
Two conductors and general shielding do not establish transmission-line impedance or communications suitability. Check pair twisting, electrical properties and device-specific cabling rules.
The published specifications identify PVC jacket material but does not give verified oil, UV, chemical or water-resistance classifications. Request test data when environmental resistance is required.
The published product graphics mention UL and the materials table references RoHS. Ask for current documents that identify the exact ordered model and applicable standards.
