Zhong Hua Jiang 18 AWG 4-Conductor Double-Shielded Cable (18/4) combines four twisted tinned stranded-copper conductors, individual PVC insulation, an aluminum shielding layer and a tinned-copper shielding layer under a PVC outer jacket. This construction is intended for compatible CNC machine controls, electronic instruments, automation cabinets and other equipment wiring where four insulated connections and electromagnetic interference management are required.
Published specifications for this 18/4 cable include 300V rated voltage, 80°C (176°F) rated temperature, 26.7 Ω/km conductor resistance at 20°C and a 6.5 ± 0.15mm overall jacket diameter. The four conductor colors are black, red, yellow and white. Confirm circuit current, cable routing, shield termination and equipment requirements before ordering; shielding alone does not establish suitability for VFD motor-output power.
Four insulated 18 AWG conductors provide distinct connection paths for compatible machine inputs, control signals, sensor supplies or auxiliary circuits. The black, red, yellow and white insulation helps technicians identify conductors, but actual assignments must follow the equipment wiring diagram. Four conductors do not automatically mean two individually twisted signal pairs.
Aluminum foil and tinned-copper shielding can reduce electromagnetic coupling from neighboring drives, switching power supplies and control equipment when installed and bonded correctly. Stranded tinned-copper cores also support solder termination and resistance to oxidation at exposed conductor surfaces. Shield effectiveness depends on the assembly, termination, routing and interference source.
For OEM harness assembly, industrial distributors, replacement wiring and wholesale procurement, share your required reel or cut length, total quantity, connector or cable-gland dimensions, electrical use, packaging requirements and destination country. Discuss model-specific documentation and any requested configuration changes before issuing an order.

The listed insulation resistance is 10 MΩ/km at 20°C and the dielectric-test entry is 2000 VAC/min. For technical approval, request the measurement method, units and acceptance criteria from the manufacturer. A 300V insulation rating does not establish the continuous conductor current permitted in a specific circuit or installation.
Request the 18AWG Four-Core Cable Data Sheet and Quote
For accurate selection, confirm the required cable length, conductor assignment, termination type, bend requirement, shielding termination and equipment electrical specifications before ordering. For continuously moving cable-carrier applications, verify whether a dedicated shielded chain cable is required.

The product data list four 18 AWG tinned stranded-copper conductors with a conductor resistance of 26.7 Ω/km at 20°C. Tin plating helps resist surface oxidation and improves solderability; it does not make copper more conductive than an equivalent unplated copper core. Evaluate cable losses with the published resistance, load current and installed cable length.

Conductor-material features are shown for comparison. Verify final cable selection using the manufacturer’s stated resistance, application requirements and supporting technical documentation rather than graphic indicators alone.
Tinned copper offers excellent conductivity, prolongs service life and is more suitable for soldering.
The cable incorporates an aluminum shielding layer and a tinned-copper shielding layer around the insulated conductors. Properly connected shielding can help reduce electromagnetic interference in control panels and equipment installed near motors, drives, relays and power converters. Shield performance depends on frequency, continuity, bonding and cable routing.
Terminate the cable shield according to the relevant CNC controller, VFD, instrument or machine manufacturer’s EMC recommendations. One-end versus both-end bonding is a system-level decision; the shield must not be substituted for a required protective-earth conductor. Keep sensitive signal cable appropriately separated from motor power wiring.

Applications to assess include CNC controller I/O connections, industrial automation panel wiring, electronic instruments, equipment-monitoring circuits, suitable stepper-drive control signals and auxiliary sensor power or feedback connections. The required circuit diagram determines how the four insulated conductors are allocated. Communication interfaces such as RS-485, CAN or differential encoders may require specified individual twisted pairs, impedance or capacitance not established by these published product details.
This general-purpose shielded control cable is not automatically a substitute for a rated motor-power cable, an inverter-to-spindle power cable, a safety-rated cable or a continuous-flex drag-chain cable. Check the actual working voltage and current, signal interface, cable movement, environment, insulation and installation standards before specifying the product.
Ask About Compatibility with Your Equipment
Match the number of cores, conductor resistance, operating current, voltage, electromagnetic environment and installation movement to the machine wiring diagram. This cable has four insulated conductors in one jacket, but its published construction does not establish two separately twisted pairs or a defined communication-cable impedance.
| Selection Item | Published Specification or Purchasing Check |
|---|---|
| Wire gauge and cores | Four twisted, tinned stranded-copper 18 AWG conductors with black, red, yellow and white insulation. |
| Electrical ratings | 300V, 80°C, 26.7 Ω/km at 20°C; verify allowable current and voltage drop for the installation. |
| Shielding | Aluminum plus tinned-copper shielding; confirm bonding, termination and EMI routing. |
| Jacket and cable entry | PVC overall jacket, 6.5 ± 0.15mm outside diameter; check gland sealing and strain relief. |
| Communications and signals | Check whether the interface requires independent twisted pairs, controlled impedance or other electrical properties. |
| Procurement requirements | Specify cut or reel lengths, overall quantity, packaging, documentation, connector requirements and destination market. |
At 20°C, the specified conductor resistance of 26.7 Ω/km is approximately 0.0267 Ω/m per conductor. For a two-conductor supply-and-return circuit, approximate loop resistance = 2 × one-way cable length (m) × 0.0267 Ω/m; multiply this value by current (A) to estimate the voltage drop. Allow for conductor temperature, connections and installation requirements. Do not infer a maximum safe current from voltage rating alone.
Send Your Four-Core Cable Requirements
| Cable Configuration | Structural Difference | When to Consider |
|---|---|---|
| 18 AWG 4-core (this model) | Four insulated 18 AWG conductors | When four compatible control or auxiliary connections are required. |
| 18 AWG 3-core | Three insulated 18 AWG conductors | When the circuit requires only three insulated connections. |
| 18 AWG 2-core | Two insulated 18 AWG conductors | For suitable two-connection control, feedback or auxiliary circuits. |
| 20 AWG 4-core | Four conductors of smaller nominal gauge | For compatible lower-current designs with different cable-entry and resistance considerations. |
| Shielded cable for drag chains | Specialized construction for repeated movement | When the cable follows an automated axis or cycles continuously in a carrier. |
The conductor count alone does not determine whether a cable is suitable for a particular encoder, differential bus, machine safety circuit or VFD output. Confirm manufacturer requirements and the individual cable drawing before treating variants as interchangeable.

This product is described with UL2464-style wiring construction and PVC (RoHS). A cable style reference or general document image does not by itself establish UL recognition or material compliance for the exact delivered model. For a technical purchase, request current product marking information, applicable certification records, declarations and required inspection results.
It is considered for compatible four-core CNC machine controls, automation cabinets, electronic instruments, sensor and monitoring circuits, and other low-voltage auxiliary wiring where reduced electromagnetic coupling is beneficial. Confirm the exact circuit requirements first.
It contains four insulated 18 AWG conductors, not four separate twisted pairs. The listed structure also includes aluminum and tinned-copper shielding inside a PVC jacket. Electrical functions are assigned by the equipment wiring diagram.
The published ratings are 300V and 80°C (176°F). Listed conductor resistance is 26.7 Ω/km at 20°C and the cable outside diameter is 6.5 ± 0.15mm. Verify the actual allowable conductor current and installation requirements.
The aluminum and tinned-copper layers can help reduce unwanted coupling of electromagnetic noise when properly terminated. Shield quality, continuity, routing, bonding and the source of interference affect the real-world result.
The answer depends on the machine controller, grounding configuration, shield termination and EMC design. Follow the equipment manufacturer’s instructions. Never use foil or braided shielding as a replacement for a required protective-earth conductor.
Both use 18 AWG conductors. The 18/3 version has three insulated conductors, whereas 18/4 provides four. Select the cable by the number of connections required; the extra conductor does not establish a dedicated protective earth without appropriate design and approval.
No continuous-flex rating is established in the supplied specifications. For repeated high-cycle motion, select a cable with confirmed cable-carrier construction, bend radius, movement speed, travel length and cycle-life suitability.
The listed supply-length range is 5m to 5,000m. Submit your required cut or reel lengths, order quantity, packaging and labeling needs to confirm available configurations before purchase.
Provide 18 AWG, four conductors, total order quantity, cut or reel length, voltage, current, signal or circuit function, connector and gland requirements, movement conditions, destination country and any required compliance documents.
Confirm the quality checks and any required inspection criteria with the supplier. Ask for the current cable specification sheet, model-specific test records and applicable conformity documentation needed for your order.
Black, red, yellow and white are listed for this model. The colors identify insulated conductors, but the electrical pinout must match your approved wiring diagram.
The listed overall jacket diameter is 6.5 ± 0.15mm. Confirm the tolerance against the selected connector, cable gland and strain relief before assembly.
Not automatically. Four insulated conductors are not necessarily assembled as two independent twisted pairs. For differential communication, confirm lay geometry, characteristic impedance, shielding and the interface specification.
Only if the actual construction meets the network’s requirements. The provided product details do not identify controlled impedance or an independent twisted-pair arrangement. Request the cable construction details before selection.
Do not assume it can. Inverter-to-motor output wiring may require a purpose-designed VFD cable, suitable insulation rating, grounding, shielding and EMC connections. This cable should be assessed against the specific application documentation.
It depends on circuit current, voltage drop, noise sensitivity, conductor allocation and installation rules. Check the machine diagram and consider separating signal and power paths when required.
The source specification states 26.7 Ω/km at 20°C per conductor. Calculate circuit losses using the total supply-and-return path and allow for actual temperature and connection losses.
18 AWG conductors are larger than 20 AWG conductors, and generally exhibit lower electrical resistance for comparable copper materials. The best selection also depends on current, space, connector entry, cable flexibility and the approved product construction.
The supplied construction refers to aluminum and tinned-copper shielding around the conductor group. It does not document four individual shields. Confirm the conductor layout if separately shielded circuits are required.
No. An AWM style describes a general construction category, not proof of recognition for every manufacturer or model. Request current product markings and the applicable certification record for the exact cable purchased.
The specification table lists 10 MΩ/km insulation resistance at 20°C and a dielectric test of 2000 VAC/min. The complete test method and criteria are not provided; obtain the current manufacturer data sheet before engineering approval.
The supplied information describes PVC insulation and jacket but does not establish IP protection, UV resistance, an oil rating or direct-burial suitability. Confirm environmental requirements with the supplier.
No. The shield serves an electromagnetic-compatibility function. Protective earth, where required, must be provided by an appropriate conductor and installation practice.
Provide required length per reel, total quantity, order destination, preferred packaging and labeling, target equipment, technical acceptance criteria and any needed compliance documentation.
