18 AWG 4-Conductor Shielded Drag Chain Cable
Zhong Hua Jiang 18AWG 4-conductor electrical chain shielded wire is a flexible multi-core cable for CNC routers, cable carriers, automated equipment, control circuits and machine interconnections. It combines four stranded, tinned-copper conductors with PVC insulation, a PVC outer jacket and electromagnetic shielding.
The cable is specified for 300V and 80°C service, with an 8.0 ± 0.25mm outer jacket diameter. Its shielded construction supports signal and control wiring installed near sources of electrical interference, subject to appropriate cable sizing, routing and shield termination.
Designed for OEM machine builders, equipment integrators and industrial cable distributors, the 18/4 cable is offered for systems requiring conductor identification, flexible installation and compatible drag-chain routing. The actual bending radius and service-life conditions should be confirmed for the motion profile of each machine.

Each 18AWG cable contains four twisted conductors made from tinned stranded copper, with PVC insulation and a PVC jacket. Cotton rope and cotton paper are listed as isolation or filling materials in the product specification. A shielding layer is included to help reduce the coupling of unwanted electromagnetic noise into connected control and signal circuits.
Tinned stranded copper conductors: provide electrical connectivity and support termination by appropriate connectors or soldering processes.
PVC insulation: keeps the four current-carrying conductors electrically separated.
Cable shielding: helps manage electromagnetic interference when terminated and grounded according to the machine manufacturer’s electrical design.
PVC outer jacket and internal filling: provide insulation and mechanical organization within the cable carrier.
For detailed material selection, ask for the current cross-sectional drawing, conductor stranding, shield coverage and approved installation parameters before incorporating the cable into a production machine.
This 18 gauge four-core shielded electrical cable is intended for machine wiring where shielded signal or control connections must pass through moving cable routes. Typical applications include limit-switch wiring, CNC auxiliary signals, sensors, actuator control lines and other electrical circuits within the cable rating.
The product is supplied as a shielded chain cable, rather than an automatically interchangeable replacement for every spindle power lead or high-current motor cable. Confirm permissible current, conductor assignment, electromagnetic compatibility and cable-carrier movement before specifying it for a VFD or motor application.
Importers and wholesale buyers can submit target lengths, annual demand, destination market and documentation requirements for a quotation. Existing product listings state an available length range of 5m to 5000m; confirm the quoted cut length and packing configuration for each order.

Tinned copper improves the conductor surface’s resistance to oxidation and can help make soldered terminations more consistent. The PVC insulation, adequate conductor spacing and appropriate cable assembly are also important for electrical performance.
Product information mentions a 15-million-cycle bending test claim. Before using this value as a design requirement, request the test report identifying bend radius, travel distance, movement speed, temperature and acceptance criteria. Actual cable life depends on the completed installation and operating environment.
Cable-carrier design should include suitable bend radius, adequate cable space, correct strain relief and separation from unsuitable high-power wiring where required.

The conductor illustrations compare tinned copper, bare copper and copper-clad aluminum. They are illustrative only: bare copper can also be soldered, and electrical performance depends on conductor cross-section, construction, plating, corrosion exposure and termination method. Request data rather than treating pictograms as laboratory test results.
A shielded cable can help reduce interference affecting CNC control systems, encoder-related circuits and industrial electronics. Proper shield termination and equipment grounding are essential; the shield itself does not replace a correctly sized protective-earth conductor.
Discuss Your Drag-Chain Wiring Application
The 18AWG four-core shielded chain cable can be considered for control and auxiliary electrical connections in CNC routers, engraving equipment, robotic assemblies, automation cabinets and moving cable carriers. Selection depends on conductor allocation, cable power rating, shielding requirements and dynamic motion conditions.
CNC router and engraving-machine auxiliary wiring, such as appropriate sensors, switches and control signals.
Cable-carrier connections on automated machinery, subject to approved dynamic bending specifications.
Shielded multi-core connections for control cabinets and electronic instruments.
Machine maintenance and OEM replacement cable where electrical and mechanical specifications match.
For continuous movement, confirm the required minimum bending radius and travel conditions. For any application carrying motor or VFD output power, verify whether this particular cable is approved for the installation rather than assuming suitability from the cable name alone.

The supplier’s published conductor-resistance value is 13.7 Ω/km at 20°C; request clarification of how this relates to the nominal 18AWG conductor size. Ask for the current datasheet and test method when resistance tolerance is a controlled procurement parameter.
Yes. A suitably designed and terminated shield can reduce electromagnetic interference coupling into a signal or control cable. Proper grounding, cable separation and termination practice remain important.
The product is offered as a flexible chain cable for moving installations. Confirm the required bending radius, travel length, speed, strain relief and verified dynamic-life conditions for the particular machine.
The product information mentions 15 million cycles, without complete test conditions. Request a corresponding test report and match those conditions to the intended installation before relying on that figure.
The available product information lists black, white, yellow, green and red despite specifying four cores. Confirm the exact four supplied colors and wiring identification with the supplier before placing an order.
The cable is marketed with UL-related wording, including a UL2464 reference. For project documentation, request the exact manufacturer UL file number and verify the relevant cable construction, printed markings and recognition or certification scope.
The supplier specification identifies its PVC insulation and jacket as “PVC (RoHS).” Buyers requiring documentary compliance should request a current model-specific declaration or material test report.
Do not assume suitability based only on shielding and the 300V listing. Confirm conductor current capacity, output-cable requirements, environmental ratings and the VFD or spindle manufacturer’s installation instructions.
Chain cable is intended for routes with repeated movement, where its bending characteristics matter in addition to its electrical properties. Ordinary shielded cable may be acceptable for fixed installations but should not be substituted in moving systems without checking approval.
No. Shield connection can form part of an electromagnetic compatibility strategy, but protective grounding must be designed separately in accordance with the equipment’s safety requirements.
The website lists a cable length range of 5m to 5000m. Supply length, cut tolerance, packaging and cable-reel details should be confirmed in the quotation for the specific order.
