Zhong Hua Jiang 20 AWG 4-conductor double-shielded cable (20/4) brings together four twisted tinned stranded-copper conductors, PVC insulation, aluminum shielding, a tinned-copper shielding layer and an overall PVC jacket. The 5.7 ± 0.20 mm outer diameter supports compact cable routing in compatible machine-control, instrumentation and electronic-equipment assemblies.
Rated at 300 V and 80°C, this four-core cable is specified with conductor resistance of 36.7 Ω/km at 20°C. Its double-shielded construction can help limit electromagnetic interference (EMI) when shielding and equipment bonding are designed correctly. Typical selection scenarios include CNC controller I/O, sensors, actuator-control signals, instrumentation and other compatible internal equipment connections.
For wholesalers and OEM buyers, this 20/4 version is differentiated by its four insulated cores and its 5.7 mm nominal outside diameter. Confirm the finished jacket tolerance (±0.20 mm) with the mating connector, strain relief or cable gland before specifying a wiring harness.

The four insulated conductors provide a convenient configuration for machine circuits needing four separate connections, such as supply and return plus two control lines, or multiple low-voltage signals. The standard core colors are black, red, yellow and white; assignments should be defined by the machine wiring diagram rather than color alone.
An aluminum foil layer combined with tinned-copper shielding can help limit coupled electrical noise from nearby motors, drives, relays and switching equipment. Actual EMI performance depends on cable routing, termination, shield coverage, connectors and the installation environment; no fixed shielding attenuation is claimed for this cable.
Zhong Hua Jiang works with equipment builders, control-panel assemblers, importers and electrical-wire distributors. For a project quotation, identify the total cable quantity, preferred lengths, four-core pinout, circuit voltage and current, connector or gland needs, intended cable movement and destination-market documents required.

The figures above are the manufacturer-listed product specifications. Before placing an order, confirm working current, voltage drop, route length, termination type, cable movement and any destination-market compliance needs. The source lists insulation resistance as 10 MΩ/km at 20°C and dielectric testing as 2000V AC/min; request the test method and units for engineering approval.
A correct purchasing specification should separate the conductor gauge from the number of cores, screening structure and installation demands. Four 20 AWG conductors are not the same as two screened twisted pairs or a cable certified for continuous moving-chain service.

At the same conductor material and construction, 18 AWG has a larger conductor cross-section than 20 AWG and generally offers lower resistance over equal lengths, while 22 AWG is smaller and generally has higher resistance. The right choice depends on length, allowable voltage drop, current demand, termination hardware and available cable space.
This product has four insulated conductors, not four separately shielded pairs. For differential communications such as RS-485, CAN or Ethernet, verify required impedance, pair geometry, capacitance and protocol-specific installation conditions rather than selecting by conductor count alone.

| Oxidation Resistance | Low Eccentricity | High Conductivity | Insulation Resistance |
Tinned stranded copper provides an electrically conductive core with a tin coating that helps protect the copper surface against oxidation and supports solder termination. Relative to a larger 18 AWG conductor, 20 AWG generally occupies less space but has higher resistance per unit length; the correct gauge must be selected from circuit current, voltage drop and wiring conditions.

Tinned stranded copper combines practical conductivity with a protective surface coating and convenient solder termination. The comparative symbols above are illustrative; actual performance depends on conductor size, construction, environment and test conditions.
The aluminum foil and tinned-copper shielding surround the insulated cores to help reduce externally coupled electromagnetic noise. Double shielding is particularly relevant when low-level control circuits share a machine environment with motors or switching devices, but the result depends on the full cable-and-equipment installation.
Terminate the cable shield according to the machine, controller or drive manufacturer’s EMC and bonding guidance. Whether to bond at one or both ends depends on the system design and interference frequencies. The shield is an EMI-control feature, not a substitute for a dedicated protective-earth conductor.
Route signal or low-voltage control conductors with appropriate separation from high-noise motor power wiring. Maintain shield continuity through the connector or enclosure according to the equipment manufacturer’s recommendations, and avoid leaving long unshielded pigtails where EMC performance is critical.
The stated 300 V insulation rating does not establish a universal current-carrying capacity. Check current, conductor heating, cable length and voltage drop under the actual operating conditions. For moving machine axes, verify the minimum bend radius and whether a purpose-designed continuous-flex cable is required.

Potential applications include CNC controller I/O circuits, sensor and limit-switch connections, low-voltage machine control, test instruments, electronics assemblies, alarm or access-control circuits and compatible auxiliary connections. In each case, verify the signal protocol, current, installation rules and environmental exposure rather than assuming compatibility from conductor count alone.
For an OEM harness, retrofit or panel-building project, match the cable to the actual connector pinout, shield connection, bend conditions, cable-gland size and controller instructions. Where a motion axis requires continuous high-cycle flexing, choose a specifically qualified moving-chain cable instead of assuming all stranded cables are drag-chain rated.
Importers, electrical distributors and CNC equipment manufacturers can streamline quotation and incoming inspection by agreeing on both electrical requirements and commercial order details before production.

Stepper motors are supplied for controlled motion in CNC machines, automation systems and related positioning applications.
Compliance and approval needs depend on the selected cable and its intended use. AWM Style 2464 is a wiring-material style designation, not independent evidence that this particular cable has UL recognition or listing. Request the corresponding manufacturer documentation, applicable certification records and RoHS declarations for the exact item ordered.
It is intended for compatible four-core electronic and machine-control connections, including CNC controller I/O, low-voltage sensors, switches, instrumentation and auxiliary equipment signals. Operating voltage, current, connectors and installation method must fit the specified cable.
20/4 means four insulated conductors, each sized 20 AWG. The supplied construction has four twisted tinned stranded-copper cores and aluminum plus tinned-copper shielding under an overall PVC jacket. It does not mean four twisted pairs.
The source lists 300 V and 80°C (176°F), conductor resistance of 36.7 Ω/km at 20°C, insulation resistance of 10 MΩ/km at 20°C and a dielectric-test entry of 2000V AC/min. Confirm test procedures and units with the manufacturer before approving the cable.
The aluminum layer and tinned-copper shield form conductive barriers that can help reduce coupling between electrical noise sources and the cable cores. Shield continuity, termination and equipment bonding determine practical performance.
Shield-bonding strategy depends on equipment instructions, frequencies of concern and the full EMC design. Follow the controller or drive manufacturer’s wiring guidance. Do not use the shield in place of a required protective-earth conductor.
Both options use 20 AWG conductors, but 20/4 contains four insulated cores and 20/3 contains three. Select four cores only when the wiring diagram calls for the fourth circuit conductor; confirm whether a separate protective-earth conductor is necessary.
It may suit approved control, sensor or feedback connections on compatible equipment. Its 300 V rating alone does not qualify it as a VFD output-power cable or motor feeder. For those circuits, use a cable explicitly approved by the drive and motor manufacturers.
A stranded conductor does not establish a continuous-flex rating. For cable carriers, verify minimum bend radius, flex-cycle rating, acceleration, travel and shielding durability; consider the dedicated shielded chain-cable range where necessary.
Length, reel packaging, labeling and other requirements can be discussed with the Zhong Hua Jiang sales team. Availability, minimum quantity, production lead time and final construction should be confirmed against the specific order.
Send the requested total quantity, cable lengths or reel size, equipment model, conductor pinout, voltage and current, intended application, cable movement, destination country and required documentation. Mention connector types and cable-gland dimensions if relevant.
Zhong Hua Jiang describes quality-control and pre-shipment inspection procedures for its product range. Buyers requiring documented acceptance criteria should specify the applicable tests, inspection reports and traceability requirements during quotation.
The specified PVC jacket outside diameter is 5.7 ± 0.20 mm. Use the tolerance range when choosing cable glands, connectors, strain relief or harness clamps.
The listed core colors are black, red, yellow and white. These colors support identification, but their electrical functions depend on the equipment wiring diagram and customer-approved pin assignment.
No. Voltage rating and current-carrying capacity are different specifications. Current selection also depends on 20 AWG conductor resistance, ambient temperature, bundling, cable length, termination and applicable installation standards.
Not necessarily. The supplier specifies four twisted conductors, but does not establish two individually twisted pairs, pair-by-pair shielding or communications-grade impedance. Check the required pairing and signal characteristics with the supplier.
Do not assume bus compatibility from four conductors and overall shielding alone. Confirm characteristic impedance, capacitance, twisting and termination needs against the device and protocol requirements.
This cable should not be selected as VFD output-power wiring without explicit manufacturer approval. VFD motor feeders may require a specially rated cable with defined insulation, grounding and shield construction.
Foil and copper shielding serve complementary interference-control roles. Foil can provide broad coverage, while conductive copper screening can support shield continuity and termination. Cable-specific effectiveness depends on construction and installation.
No. AWM Style 2464 describes a wiring-material style, while UL recognition or listing of a specific cable requires verifiable certification information. Ask for the applicable manufacturer and certification records for the product being purchased.
No. The shielding layers are used for interference control and should not replace the protective-earth conductor required by the electrical installation or equipment design.
Depending on the destination market and project, request the current specification sheet, approval or conformity documents for the exact model, relevant test details, and packaging or identification information needed for product traceability.
A numerical bend radius is not provided in the supplied specification. Contact the manufacturer to confirm the permissible bend radius and whether the intended installation requires a continuous-flex design.
Send the required cut or reel lengths, overall quantity, conductor assignment, termination requirements, labeling and packaging preferences. The manufacturer can then confirm options and commercial terms for your order.
